Testo 550 Kit 1
Testo 550 Clamp Probe
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 three ways: either attached to the instruments as shown, or connected via a cable or mounted on an optional wireless handle. The clear back-lit display can be switched between relative humidity, wet bulb, and dew point at the touch of a button. This is an excellent instrument to monitor the R/A wet bulb temperature at the condenser while charging a fixed orifice refrigeration system. You will no if the load changes and can recalculate required superheat on the fly. This is one awesome tool.
