0636 9771

0636 9771 is a high-precision temperature-humidity probe with Bluetooth. Use the High-precision humidity/temperature probe with the compatible Testo 440 multifunction measuring instrument (sold separately) to measure relative humidity and air temperature. Wet bulb temperature, dew point and absolute humidity are calculated at the same time. Measurement Values are transmitted via Bluetooth, up to 65 feet. With the proven quality from Testo, you can depend on reliable measurement results, this humidity/temperature probe is equipped with our high-precision, long-term stable humidity sensor. This allows you to measure humidity with an accuracy of ±(0.6% RH + 0.7% of m.v.) in the range between 0 and 90% RH and is traceable to international humidity standards, such as ILAC, PTB and NIST.

• Measuring range from -20 to +70°C(temperature - NTC), 0 to 100%RH(humidity - capacitive)
• Dimension is 290 x 50 x 40mm
• Operating temperature range from -5 to +50°C
• 12mm diameter probe shaft, 140mm length probe shaft
• 4 x type AA batteries
• 20m radio range
