RH-200 Relative Humidity Generator

RH-200

A compact, bench-top RH Generator providing air/nitrogen flows with precision relative humidity for use with X-Ray Diffractometers, TGA, TMA and more.

The RH-200 unit, introduced by VTI Corporation over ten years ago, is now supplied, serviced and supported by L&C Science and Technology. This CE-marked, field-proven RH generator is the preferred instrument, when a precise and stable RH environment is required. With hundreds of units in operation worldwide, scientists have come to rely on its solid performance and flexibility in operation.

The RH-200 has a footprint of only 8“ wide x 14“ deep and height of 14“.

General Description

The Model RH-200 Relative Humidity Generator is a fully automated, compact, portable bench-top instrument which supplies a specified constant air or nitrogen flow rate with a precision-controlled relative humidity. The RH-200 is designed to easily integrate with a variety of target systems…laboratory instruments such as X-Ray Diffractometers, TGA, TMA, DMA, calorimeters and micro-calorimeters, as well as glove boxes and environmental chambers.

With a wide dew point range and flow rate range, this compact portable unit can be customized for unique applications. The RH-200 is easy to install, operate and maintain.

Optional features include a Remote Sensor to interface the RH-200 directly into the sample zone of the target instrument and a Heated Transfer Line, with adjustable temperature control, to eliminate condensation between the RH-200 and the receiving instrument.

RH-200 Specifications

  • Relative Humidity range from 3% to 95% RH, with control to ±1.0%RH
  • Optional Heated Transfer Lines available for 110 or 220 volts, 1 or 2 meters long, complete with heater, thermocouple and temperature controller
  • Temperature range from Ambient to 50°C at target instrument. Dew Point range from -25°C to 50°C. A chilled-mirror Dew Point Analyzer provides stable, accurate measurement
  • Optional Remote RH Sensor can monitor target instrument, recording the delivered %RH and temperature through the RH-200 software
  • Standard flow rate is 500 cc/min with options up to 5 liters/min. RH-200 uses two mass flow controllers to regulate the flow of dry and saturated gas
  • RH-200 is fully computerized, providing user-friendly LabWindows software with on-line graphics. Software allows for step variations in both temperature and RH

Custom RH Generators

The Model RH-200 Relative Humidity Generator serves as the basis for a range of customized precision, computer controlled RH generators to meet your specific requirements.

  • All of the unique design principles of the RH-200 are employed within our customized generators.
  • A complete computer system, customized as needed, provides proprietary L&C software for your specific application.
  • For custom RH generators, Relative Humidity range can be as low as 2% to as high as 98% RH, with control to ±1.0%RH. (Standard RH-200 has Relative Humidity range from 3% to 95%.)
  • For custom RH generators, temperature at target instrument can range from Ambient to 80°C. (Standard RH-200 provides temperature at target instrument with range from Ambient to 50°C.)
  • For custom RH generators, flow rates can be up to 10 liters/min. (For the standard RH-200, flow rates can be up to 5 liters/min. using standard flow rate options.)
