Digital Psychrometer
External Probe Temperature measurements for differential
Calculates T1-T2 differential (Air Temperature minus External Probe Temperature)
Features:
•
Simultaneous display of %RH, Temperature and
Dew point or Wet Bulb or Probe Temperature
•
Wet bulb measurements without slinging
•
Calculates T1-T2 differential (Air Temperature minus
External Probe Temperature) using optional probe (TP890)
and T2-Dew Point
•
Unique sensor cap design twists to closed
position for protection during storage
•
Switchable °F/°C temperature units with 0.1° resolution
•
Data Hold freezes current reading on display
•
Max/Min readings
•
Auto power off to save battery life
•
RH300 complete with 2 AAA batteries
•
Optional external temperature probe (TP890)
•
Optional kit RH305 includes RH300, temperature probe,
33% and 75% calibration bottles, and carrying case
