Customizable, Plug-and-Play Gas Detection Systems


RH200 Dew Point Generator

The Model RH-200 RH Generator is a fully automated, compact and portable bench-top instrument which easily and quickly interfaces with other laboratory systems to provide a specified constant flow of gas at a precision-controlled relative humidity.

Features/Specifications of the RH-200

  • Integrates with laboratory instruments such as X-ray diffractometers, TGA, TMA, DMA and calorimeters and also with glove boxes, environmental chambers and more
  • Relative humidity range from 2% to 98% with precision-controlled accuracy of RH to ±1.0%
  • Flow rates up to 500 sccm are standard with optional ranges available up to 5 liters/min
  • Provides gas stream with controlled RH and flow for desired temperature from ambient to 50°C at the target instrument
  • Compact design with 8” wide x 14” deep footprint
  • Customizable options are available to meet a broad range of applications – see reverse side
