2500 Humidity Generator - MBW

2500 Humidity Generator - MBW

The Model 2500 Benchtop Humidity Generator is a self contained system capable of producing atmospheres of known humidities using the fundamental, NIST proven, “two-pressure” principle. This system is capable of continuously supplying accurately known humidity values for instrument calibration, evaluation, and verification, as well as for environmental testing. Simply apply power and the 2500 will power-up ready to generate. 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.

3900 Humidity Generator - MBW

3900 Humidity Generator - MBW

The Model 3900 Low Humidity Generator is an extremely accurate means of producing known humidity values for calibrating and verifying humidity instrumentation. Based on the combined, NIST proven, fundamental “two-pressure” and “two-temperature” principles, this system will automatically supply a continuous humidified gas stream, within the frost/dew point range of –95.0 °C to 10.0 °C, for days or even weeks unattended. Simply apply power to the system, and the 3900 will power-up ready to purge and/or generate. Humidity setpoint values are input by the operator from the front panel keypad and are limited only by the operational range of the 3900 Humidity Generator.

HFG1 Flow Mixer - MBW

HFG1 Flow Mixer - MBW

The HFG1 allows users generate variable dew or frost point gas flows for the calibration of all types of hygrometers. It works by combining a dry gas supply with adjustable amounts of water vapor provided by an internal permeation humidifier. By adjusting the mixing ratio using the front panel mounted valves, output dew/frost points are generated for measurement using a reference hygrometer such as the 973 or 373.

Easy to Set Up
HFG1 takes only a few minutes to set up. Fill the permeation humidifier with distilled water, connect the reference hygrometer to outlet 1, connect the inlet pressure, set the regulator to the required working pressure and adjust the flow rate to the required value. Outlet 2 is connected to the instrument(s) under test using standard tubes and fittings.
