Model 2000 Humidity Temperature Calibrator.
The Model 2000 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.
The system design provides a capability to perform calibrations of chart recorders with remote probes or do a simultaneous linearity test of multiple data loggers.
The Model 2000 can also be used for a fast assessment of dew point instruments.

• 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.

Unlike larger systems, the Model 2000 reaches equilibrium within minutes, thus enabling a full range calibration in much shorter times. The flexibility of the system gives laboratories a means for continuous calibration while larger systems are being used for other tasks requiring extended calibration times.
The Model 2000 measures and controls RH directly. This eliminates the need for any conversions or computations that often lead to additional errors. In general, the Model 2000 Humidity Calibrator will generate chamber conditions for accurate and repeatable calibration of instruments, probes, recorders and data loggers.
