Specification
High accuracy thermohygrometer testo 635
For standard atmospheric environment probe or separate humidity and temperature probes. With calibration protocol and battery. Without probe. The dew point value between the environmental air and surfaces can be determined with separate probes. Relative humidity and temperature are displayed simultaneously, the dew point is determined at the touch of a button. Data is documented using the accessory Testo logging printer.
Measuring ranges:
Combination probe: 0 to 100 %R.H.
-20 to +140 °C
-50 to +100 °C td (Dew point)
Temperature probe: -50 to 1000 °C (NiCr-Ni)
Accuracy: (Moisture see probe)
-40 to +900 °C: ±1 °C, ±0.5 % Meas. value.
±2 °C, ±1 % Meas. value: rest of range
