OHG-4
The Owlstone Humidity Generator (OHG-4) is a versatile humidity generator that is used to produce a range of relative humidity concentrations from 1 to 90%RH (±1%).
Overview
Designed to be mounted in the Gen-Sys rack, the OHG-4 can be used in conjunction with your OVG-4 or V-OVG to generate a wide range of vapor standards, suitable for calibration of sensors, especially gas sensors.
