Thunder Scientific Model 9500 Automated “Two-Pressure” Humidity Generation Syste

Automated Humidity Generation System FEATURES • Traceable to SI 1 • 0.3% of Reading RH Uncertainty 5 • High Flow Capability • Based on NIST Proven “Two-Pressure” Principle • Generate: RH, DP, FP, PPM, Multipoint Profiles • Computes System Uncertainties in Real Time • Automatically Applies Enhancement Factors • ControLog® Automation Software The 9500 Humidity Generation System is capable of producing known humidity values using the fundamental, NIST proven, “two-pressure” principle. The 9500 is capable of continuously supplying relative humidity, dew point, frost point, parts per million, or...

ControLog Computer Screen Temperature Controlled Bath: The 9500 humidity generating system incorporates an extremely stable temperature bath. Bath temperature is digitally controlled by the computer to any value between 0 °C and 72 °C using PID (proportional-integral-derivative) algorithms. The test chamber, saturators, heat exchangers, and connecting tubing are immersed in approximately 20 gallons of distilled water that is circulated at the rate of 50 gallons per minute by a magnetically coupled centrifugal pump. Fast fluid circulation provides the temperature conditioning of these...

Automated Humidity Generation System SPECIFICATIONS RIGHT VIEW REAR VIEW LEFT VIEW 1. Traceable to the International System of Units (SI) through NIST-maintained standards. 2. Using glycol/water as the temperature bath heat transfer fluid from 0 to 5 °C and water as the temperature bath heat transfer fluid from 5 °C to 72 °C. 3. Temperature Control Stability is defined as the maximum deviation from a best fit line, as measured by the bath temperature control sensor. If data is logged digitally, the best fit line will be defined as the average value over the 10 minute period. All...
