  • General Tools RHMG650 9-in-1 Temperature-Humidity Meter with Pin/Pinless Moisture Meter

The super-versatile #RHMG650 is ideal for water damage restoration contractors, facilities maintenance professionals and HVAC system installers/technicians.

Features:

  • Measures 1) ambient temperature, 2) relative humidity (RH), 3) absolute humidity (in mg/L or g/m3), 4) GPP (mixing ratio—in grains per pound or g/kg), 5) relative moisture level using the pinless sensor, 6) absolute moisture level 
  • Stores/recalls 20 pairs of temperature and RH readings
  • Adjustable high and low alarms for RH, relative moisture level and absolute moisture level
  • Backlit LCD with 3-digit primary readout + 4-digit secondary readout
  • 33% (HR33) and 75% (HR75) reference salts are available to perform a diagnostic check of the RH sensor. The sensor itself is not calibratable outside of a lab
  • Min/max memory + data hold
  • Auto power off
