Testo 625 Thermo-Hygrometer Wireless Kit

The Testo 625 is an ideal entry level instrument for IAQ and IEQ measurements of temperature and humidity. Use it to monitor hard-to reach points in AC and heating system ducts, environmental changes in remote rooms or storage areas, anywhere you need to be two places at the same time or only have one hand free to work. The Testo 625 temp/RH probe can be used attached to the instrument as shown, or mounted on the included wireless handle. The clear back-lit display can be switched between relative humidity, wet bulb, and dew point at the touch of a button.
