OHG Humidity Generator
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%).
OFC Flow Controller
The Owlstone Flow Controller can be fully integrated into your GEN‑SYS modular system for secondary dilution and ultra-low concentrations. It works alongside our calibration gas and humidity generators.
