Ammeter Price in Bangladesh 2026 – Buy Genuine Analog & Digital Ammeters
The Ammeter price in Bangladesh starts from ৳4,000 at astzbd.com, with genuine Taiwan-made analog AC and DC bench meters covering everything from educational lab work to industrial panel monitoring. An ammeter looks simple on the surface, but connecting the wrong type or mismatching the measuring range to your circuit can either damage the instrument or give you a reading you can’t trust — so getting the specification right matters more than most first-time buyers expect.
Ammeter Overview – Accurate Current Measurement for Lab, Industrial & Educational Use
An ammeter measures the flow of electric current through a circuit, connected in series so the current passes directly through the meter itself. Whether you’re running a physics lab session at a university, monitoring current on an industrial control panel, or troubleshooting a DC circuit at your workbench, the Ammeter price in Bangladesh reflects a tool built for precision that most electrical work simply can’t skip.
How Does an Ammeter Work?
Moving-Coil Mechanism (Analog)
Inside an analog ammeter, a coil suspended in a magnetic field rotates proportionally to the current passing through it, driving a pointer across the dial face.
Magnetic Field, Pole Pieces & Pointer Deflection
Permanent magnetic steel and pole pieces create a consistent magnetic field, and as current flows through the coil, the resulting force deflects the pointer to indicate the measured value.
Digital Sensor, Shunt Resistor & Display Conversion
Digital ammeters use a shunt resistor to convert current into a measurable voltage, which internal circuitry then processes and displays as a direct numeric readout.
Series Connection Principle in a Circuit
An ammeter must be wired in series with the circuit under test, since current has to flow directly through the meter for an accurate reading — connecting it incorrectly is one of the most common causes of meter damage.
Types of Ammeters We Offer
Analog/Moving-Coil Ammeter
The SEW ED-305 Analog AC Ammeter, priced at ৳4,500, uses the classic moving-coil design trusted in labs and panels across Bangladesh for decades.
Digital Ammeter
While our current stock focuses on proven analog bench meters, digital ammeters offer instant numeric readouts for applications where fast, precise readings matter more than dial-style visualization.
AC Ammeter vs DC Ammeter
The Analog AC Ammeter ED-205 (AC50/500mA/5A) handles alternating current circuits, while the Analog DC Ammeter ED-205 (DC50/500mA/5A) is built specifically for direct current applications — using the wrong type for your circuit gives inaccurate or unstable readings.
Panel-Mount Ammeter
The Analog AC Ammeter Bench Meter ED-205 (AC50/5A 100V) is designed for permanent panel installation, giving continuous current visibility on control boards and equipment enclosures.
Portable/Handheld Ammeter
For fieldwork and mobile troubleshooting, portable ammeters or multimeters with current-measuring modes offer flexibility that fixed panel meters can’t match.
Clamp-Type Ammeter (Non-Contact Measurement)
A clamp-type ammeter measures current without breaking the circuit, clamping around a live wire instead — useful for quick checks where interrupting a running system isn’t practical.
Key Features & Technical Parameters to Check
Measuring Range (mA to A)
Match the range to your actual application — the SEW ED-305 covers 25/100/1000mA, suited for lower-current lab and testing work, while the ED-205 models handle up to 5A for broader industrial use.
Accuracy Class (Class 1.0, 1.5, 2.5)
A lower accuracy class number means tighter precision, which matters more for lab measurement and quality control than for basic panel monitoring.
Dial Angle, Display Type & Readability
Most analog bench meters use a dial angled around 40 degrees for comfortable reading, whether mounted on a panel or placed on a workbench.
Damping Time & Response Speed
A shorter damping time means the pointer settles faster after a current change, which is useful when you’re taking repeated readings across a session.
Sensitivity (mV Rating)
Sensitivity determines how small a current change the meter can detect and display, directly affecting measurement precision.
Magnetic Screening Grade
Proper magnetic screening protects the meter from external magnetic interference, keeping readings stable even near other electrical equipment.
Terminal Configuration & Wiring
Correct terminal identification and wiring polarity, especially on DC models, prevents reverse-current damage during setup.
Operating Temperature & Humidity Tolerance
Meters rated for standard ambient conditions (roughly 23°C with moderate humidity) perform reliably in typical lab and workshop environments across Bangladesh.

Why Correct Current Measurement Matters in Every Circuit
An overloaded or misread current can burn out components, trip breakers unexpectedly, or mask a developing fault before it becomes a serious failure. This is exactly why the Ammeter price in Bangladesh for a genuine, properly rated instrument is worth paying over an unverified alternative — a few thousand taka spent on an accurate meter protects equipment worth far more.
Analog vs Digital Ammeter – Which One to Buy?
| Feature | Analog Ammeter | Digital Ammeter |
|---|---|---|
| Readability | Dial and pointer, requires practice | Instant numeric display |
| Accuracy | Reliable, no battery dependency | Reliable, but battery-reliant |
| Response Time | Slightly slower (damping) | Near-instant |
| Price Range (BD) | ৳4,000 – ৳4,500 | Comparable or higher |
| Best For | Panel monitoring, lab teaching | Quick precise readouts |
For panel installations and educational demonstrations where students need to see needle movement in real time, an analog ammeter like the ED-205 series remains the standard choice. For fast, exact numeric readings, a digital option is worth considering.
AC Ammeter vs DC Ammeter – Which One Fits Your Application?
| Feature | AC Ammeter | DC Ammeter |
|---|---|---|
| Circuit Type | Alternating current | Direct current |
| Measurement Method | Responds to changing current direction | Fixed polarity, direct reading |
| Typical Use Case | Power panels, mains monitoring | Battery circuits, DC lab experiments |
Using an AC ammeter on a DC circuit, or vice versa, gives an unreliable reading or no reading at all — always confirm your circuit type before ordering.

How to Use an Ammeter – Quick Setup Guide
Zero-Point Calibration Before Use
Check and adjust the pointer to zero before taking any measurement, since even a small starting offset skews every reading that follows.
Correct Series Connection in the Circuit
Break the circuit at the point you want to measure and connect the ammeter in series, making sure polarity is correct on DC models.
Reading the Dial or Digital Display
Read the value directly from the dial position or digital display once the pointer or number has stabilized.
Avoiding Overload Damage
Estimate the expected current beforehand and select a range above that value to prevent overloading and damaging the meter.
Ammeter Maintenance & Precautions
Avoid bumping or vibrating the meter, especially analog models with sensitive internal coils, and never attempt to dismantle the unit yourself. Keep it clean and away from corrosive gases or strong external magnetic fields, and store it within the manufacturer’s recommended temperature and humidity range to protect long-term accuracy.
Common Mistakes to Avoid When Using an Ammeter
Connecting an ammeter in parallel instead of series is one of the most frequent and damaging mistakes, since it creates a near short-circuit path through the low-resistance meter. Skipping the zero-point check before use, ignoring polarity on DC models, and selecting too low a range for the expected current are other common errors that either damage the instrument or produce unreliable readings.
Ammeter FAQ
What is the difference between an ammeter and a multimeter?
An ammeter is dedicated to measuring current only, while a multimeter combines current, voltage, and resistance measurement in a single instrument.
How do I connect an ammeter correctly in a circuit?
The ammeter must be connected in series, meaning you break the circuit at the measurement point and route the current directly through the meter.
What accuracy class is best for lab use?
For educational and general lab work, an accuracy class of 1.5 to 2.5 is typically sufficient, while precision industrial applications may require tighter tolerances.
Can an ammeter be damaged by overload?
Yes, connecting an ammeter to a current higher than its rated range can damage the internal coil or circuitry, so always estimate current beforehand.
What’s the difference between AC and DC ammeters?
An AC ammeter measures alternating current that changes direction periodically, while a DC ammeter is built for the constant, one-directional current found in battery-powered circuits.
Why must an ammeter have low internal resistance?
Low internal resistance ensures the meter doesn’t significantly alter the current it’s measuring, keeping the reading close to the circuit’s true value.
Can a digital ammeter measure both AC and DC current?
Some digital models support both AC and DC measurement modes, but this depends on the specific meter’s design, so always check the specification before use.
