Precision Humidity & Temperature Calibration System
The Model 2000SP is a low cost, high accuracy alternative to RH calibrations that use chilled mirror or 2-pressure systems, and is faster than procedures using saturated salts. The system incorporates advanced electronics and innovative approaches resulting in an overall improvement in performance and reliability.

      • Equilibrium of chamber temperature and RH less than 10 minutes
      • Chamber control probe maintains accurate calibration for 12 months
      • Accurate system calibration includes controllers and probe characteristics
      • Direct control readout of RH and temperature eliminates conversions or calculations
      • Precise control of RH and temperature using direct input from the internal probe
      • Lightweight and transportable for immediate in-plant and laboratory RH calibrations
      • Temperature compensated control probe means high accuracy over wide RH range
      • RS-485 output (optional) for computer control of automatic ramp and soak cycles.
