Introduction
DTWH Handheld Multichannel Thermo-Hygrometer / Temperature Humidity Meter is a high-precision instrument that can be used to accurately measure the relative humidity and temperature of the environment, and the management system performs display analysis.
Function
1. The probe of DTWH Multichannel thermo-hygrometer can be connected to a high-precision temperature sensor with fast response, which can quickly and accurately measure.
2. It can display the measured relative humidity value and temperature value at the same time.
3. DTWH Temperature Humidity meter has an accuracy of ± 1.5% RH / 0.8% RH in the entire humidity measurement range.
4. The accuracy of this product is ± 0.1 ℃ in the whole temperature measurement range.
5. This product has a resolution of 0.001 ° C and 0.01% RH.
6. This product is equipped with management software, which can support up to 32 calibrators for simultaneous data collection.
7. This product has a zero mark function to measure the humidity fluctuation.
