Humidity Sensors And Chart Recorders: Insert humidity probes through the two inch port in the side of the chamber or place hygrothermographs into the chamber and you can: determine humidity calibration accuracy and characterize humidity sensitivity by subjecting the sensing system to a variety of humidity levels perform operational checks such as the sensing systems capability to correctly calculate and display other humidity parameters determine the repeatability, stability, hysteresis, and drift characteristics of various humidity sensing systems.Ĭhilled Mirror Hygrometers: Install the actual chilled mirror head into the chamber or insert a sample tube through the test port and draw a sample through the chilled mirror head and you can: verify mirror temperature measurement accuracy (calibration) when the The output of the device under test may then be compared with the generator's printed data for analysis. Virtually any humidity and temperature point may be generated, for any length of time, within the operational limits of the generator. The fluid jacketed test chamber can accommodate humidity sensors, hygrothermographs, chilled mirror hygrometers, and various material samples for environmental testing.

Relative Humidity Uncertainty: P c T c 1Ĭhamber Fluid Temperature Range: (Optional)Ĭhamber/Saturation Temperature Uncertainty: 1 Precision humidity generation is determined by the accuracy of the pressure measurements and on the accuracy and uniformity of temperature throughout the generating system. Humidity produced is solely dependent on the measurement of pressures and temperatures and does not rely on any other device (such as a dew point hygrometer, psychrometer, or humidity sensor) for the measurement of water vapor content.

To generate a known humidity, the computer controls the pressure ratio Pc /Ps utilizing the enhancement factor ratio fs/fc and the effective degree of saturation es/ec. Relative humidities are calculated from the measurements of pressure and temperature with the formula: Humidity setpoint values are input by the operator from the front panel keypad and are limited only by the range of the 2500 humidity generator. Simply apply power and the 2500 will power-up ready to generate. This system is capable of continuously supplying accurately known humidity values for instrument calibration, evaluation, and verification, as well as for environmental testing.
