Professional HVAC monitoring
The TM-182 is a handheld temperature and humidity meter built for HVAC inspection. It displays both values simultaneously on a dual LCD with real-time data, dew-point and wet-bulb calculations, and an audible alarm function. Electricians and facility technicians use it to verify environmental conditions on site.
Simple setup with USB logging
Power the meter with a 9 V battery or a 9 V/300 mA AC adapter, then connect the USB PC interface to transfer up to 30000 data sets. A low-battery indicator and overload display warn of power issues before readings drift. The only common snag is forgetting that the battery is not included in the box.
Steady readings over long sessions
Sampling once per second, the unit maintains 0.8 °C accuracy from 0 °C to 40 °C and 3.0 %RH accuracy between 20 %RH and 80 %RH. Auto power-off preserves the supply during idle periods, while the back light keeps the display legible in dim plant rooms. Accuracy widens to 2.0 °C outside the core temperature band.

Questions about this item
How can I confirm the TM-182 is logging correctly after I power it on?
The dual LCD will show real-time readings updating once per second, the data-hold icon appears when you press HOLD, and stored records accumulate up to 30000 data sets in memory.
What ships in the box and what must I supply myself?
The meter itself is included; you must provide a 9 V battery (NEDA 1604, IEC 6F22 or JIS 006P) or a 9 V/300 mA AC-to-DC adapter for power.
Which measurement range should I rely on for typical HVAC work?
For HVAC inspection use the humidity range 1 %–99 % RH and the temperature range -20.0 °C–60.0 °C (-4.0 °F–140.0 °F) with 0.1 % RH, 0.1 °C and 0.1 °F resolution.
