Frequently Asked Questions (FAQ) UNI-T UT331+ Temperature Humidity Meter

Q1: What does the UNI-T UT331+ Temperature Humidity Meter measure?

The UT331+ measures four parameters: ambient temperature (°C or °F), relative humidity (% RH), dew point temperature, and wet bulb temperature. All four values appear simultaneously on the LCD display, giving you a complete picture of your indoor climate at a glance.

Q2: How accurate is the UT331+ for humidity measurement?

The UT331+ achieves ±3% RH accuracy within the 40%–70% RH range at 25°C, and ±5% RH outside that range. For temperature, it delivers ±1°C (±1.8°F) accuracy across its full range, making it suitable for professional applications like pharmaceutical storage and server room monitoring.

Q3: Can I use the UT331+ in a warehouse or cold storage room?

Yes. The UT331+ operates in environments from 0°C to 50°C with humidity up to 80% RH. For cold storage rooms below 0°C, keep the device near the room entrance or use it as a spot-checker rather than a continuous monitor, since the operating range starts at 0°C.

Q4: Does the UT331+ record data over time?

The UT331+ stores MAX and MIN values recorded since the last reset. It does not feature continuous data logging to a PC or memory card. If you need continuous data logging, consider the UNI-T UT352BT or UT171A models available at AstZBD.

Q5: What batteries does the UT331+ use, and how long do they last?

The meter runs on 3 × AAA (1.5V) batteries, which UNI-T includes in the box. With normal use and auto power-off enabled, batteries last approximately 300 hours. The device shows a low-battery indicator when replacement is necessary.

Q6: Is the UT331+ suitable for a baby nursery or bedroom?

Absolutely. Many parents use the UT331+ to maintain a comfortable temperature of 20–22°C and humidity between 40%–60% in nurseries and bedrooms. The alarm function notifies you when readings move outside your set comfort range, so you can act quickly.

Q7: Does AstZBD provide warranty support for the UT331+?

Yes. AstZBD provides the full 1-year UNI-T manufacturer warranty on every UT331+ sold. If the device develops a fault under normal use within 12 months, contact AstZBD support and we will arrange repair or replacement at no extra cost to you.
