The Extech RH600 accurately measures and datalogs dew point levels in compressed air systems. This high-precision meter can help manufacturing professionals protect product quality while avoiding damaged pneumatic equipment, corrosion, and problems in cylinder and valve systems. Featuring a color graphical display, the RH600 provides clear, stable readings, allowing you to measure dew point temperature down to -50°C (-58°F) in max ambient pressure of 20 bar. Set high/low audible and visible alarms for temperature, relative humidity, and dew point thresholds. You can also easily log and transfer recorded data to a PC in CSV format to create inspection reports fast.
