The Testo 625 Digital Thermohygrometer measures temperature with an NTC sensor from –10 °C to +60 °C and with a Type K thermocouple from –200 °C to +1 370 °C, both with 0.1 °C resolution. Its temperature accuracy is ±0.5 °C for the NTC range and the humidity sensor covers 0 to 100 % rH with ±2.5 % rH accuracy between 5 and 95 % rH. Humidity readings are displayed to the nearest 0.1 % rH, and the device runs on a standard 9 V block battery (6F22)
