Cable Tester Price in Bangladesh 2026 – Buy Genuine Lutron CB-933 Cable Identifier

The Cable Tester Price in Bangladesh reflects a specialized diagnostic instrument, and astzbd.com stocks the genuine Lutron CB-933, a Taiwan-manufactured cable identifier built to trace and identify individual cores in multi-way cables. If you’ve been comparing a basic RJ45 network tester against something built for real cable tracing work, the CB-933 stands out by identifying up to 16 individual cores within a single cable — a capability most consumer-grade testers simply don’t offer.

Cable Tester Overview – Diagnose Wiring Faults Instantly

A cable tester lets you verify wiring integrity without physically cutting into a cable or guessing which core connects where. The Lutron CB-933 goes further than basic continuity checkers by pairing a 17-alligator transmitter with a dedicated receiver unit, letting a technician identify and trace up to 16 cores from one end of a cable to the other — essential when working with unlabeled multi-way cables in communication, heating, or water supply installation systems.

How Does a Cable Tester Work?

Transmitter-Receiver Core Identification

At one end of the cable, the transmitter connects to each core using its 16 numbered channel leads plus a common reference lead, while the receiver at the other end confirms which core corresponds to which channel — solving the exact problem of untangling unmarked wiring bundles.

LED Display Readout

A two-digit seven-segment LED display on the receiver clearly shows which channel number is active, removing guesswork when identifying cores across a long or complex cable run.

Wide Application Beyond Networking

Because the CB-933 works on any multi-core cable rather than just network cabling, it also connects to metal heating systems and water supply installation systems for the same core-identification purpose.

Lutron CB-933 Key Features

17-Alligator Transmitter, 2-Alligator Receiver

The transmitter’s 16 numbered channel clips plus a common reference clip let you test extensive multi-way cables in a single setup, while the receiver’s 2 clips keep the far-end connection simple.

Identifies Up to 16 Cores in Multi-Way Cable

This is the CB-933’s core strength — tracing which wire goes where across a bundle of up to 16 individual conductors, a task that would otherwise require painstaking manual continuity checks one wire at a time.

High-Impact ABS Plastic Housing

Both the transmitter and receiver use durable ABS plastic casing, built to handle repeated field use during cable maintenance and installation checks.

Clear LED Readout for Easy Operation

Two red LED lamps on the transmitter and a two-digit LED display on the receiver make results easy to read even in typical field lighting conditions.

Battery-Powered for Field Portability

Running on standard 9V alkaline batteries (transmitter and receiver each use one), the CB-933 works anywhere without needing mains power, making it genuinely portable for site visits.

Why a Proper Cable Tester Saves Time on Network & Wiring Installation

Tracing wires in an unlabeled multi-way cable by manual continuity checking, one core at a time, can turn a quick installation job into hours of tedious work. The CB-933’s transmitter-receiver design identifies all 16 cores from a single setup, cutting diagnostic time dramatically compared to basic single-wire testers — which is exactly why the Cable Tester Price in Bangladesh for a proper identification tool is a worthwhile investment for anyone doing regular cable installation or maintenance work.

Basic Continuity Tester vs Lutron CB-933 Core Identifier – Which One to Buy?

If you only need to confirm a single network cable isn’t broken, a basic RJ45 continuity tester covers that. For tracing and identifying individual cores within a larger, unlabeled multi-way cable bundle, the CB-933’s transmitter-receiver system is purpose-built for exactly that job.

What Affects the Price (Core Capacity, Build Quality, Certification)

A cable tester’s core-identification capacity is the biggest price factor — a unit that traces 16 individual cores with a dedicated transmitter-receiver pair costs more to manufacture than a basic single-wire continuity checker. ISO-9001, CE, and IEC1010 certification also reflect verified build quality and safety compliance that unbranded alternatives often lack documentation for.

Why Buy Genuine Lutron Cable Testers from astzbd.com

astzbd.com stocks the genuine Lutron CB-933 with full manufacturer specifications and certification, protecting you from unverified imports that may not deliver the same core-identification accuracy or safety compliance.

Who Should Buy the Lutron CB-933 Cable Tester?

Network Installers & IT Technicians

Identifying which core connects where within multi-way cable bundles speeds up structured cabling installation and troubleshooting significantly.

Electricians & Building Wiring Contractors

The CB-933’s applicability to heating and water supply installation wiring, not just communication cables, makes it a versatile tool for broader electrical contracting work.

Telecom Field Engineers

Tracing individual cores in unlabeled communication cable bundles is a routine but critical task in telecom infrastructure maintenance.

Facility Maintenance Teams

Ongoing building maintenance often involves diagnosing which wire in a bundle serves which function — exactly the problem the CB-933 is designed to solve.

How to Use the Lutron CB-933 – Testing Guide

1. At one end of the cable, connect the transmitter’s numbered leads (CH1 to CH16) to each core under test
2. Connect the transmitter’s “COM” reference lead to a core you can positively identify
3. At the far end, connect the receiver’s leads to the cores you want to identify
4. Read the receiver’s LED display to see which channel number corresponds to that core
5. Repeat across all cores in the bundle to complete a full cable map
6. Record your findings before disconnecting to avoid re-testing

Cable Tester Maintenance & Care Tips

Replace the 9V batteries in both the transmitter and receiver when the LED display dims or becomes inconsistent, store both units in their case to protect the ABS housing from impact damage, and inspect the alligator clips periodically for corrosion or loose connections that could affect reading accuracy. Keep the cable resistance within the rated 25KΩ maximum for reliable results.

Cable Tester FAQ

What is the Lutron CB-933 cable tester used for?

It identifies and traces up to 16 individual cores in multi-way cables, commonly used for communication cable maintenance and also applicable to heating and water supply installation wiring.

How many cores can the CB-933 identify at once?
