The Wintact WT83 is a small, portable humidity and temperature meter. It measures ambient temperature from -20 to 70 °C and relative humidity from 0 to 100 %RH, shows dew point and wet-bulb temperature, and offers MAX/MIN, data hold, backlight and automatic power-off.
The Wintact WT83 is a mini humidity and temperature meter with a small, portable design. The manufacturer describes it as offering safe and reliable performance stability, low power consumption and high precision.
The meter measures surrounding temperature from -20 to 70 °C (-4 to 158 °F) with an accuracy of ±1 °C between 5 and 50 °C, and relative humidity from 0 to 100 %RH with an accuracy of ±4 %RH at 25 °C between 10 and 90 %RH (±5 %RH over the full range). It also displays dew point and wet-bulb temperature from -20 to 50 °C, with a maximum response time of 30 s.
The backlit LCD shows two readings at once, and the meter runs on three 1.5 V AAA batteries. It switches off automatically after about 15 minutes without operation, and this function can be cancelled when continuous measurement is needed.
