Relative Humidity Generator

The generator is suitable for achieving relative humidity ranging from 10 to 95 with uncertainties of under 1 at ambient temperature and can be used for the calibration of relative humidity instruments in the laboratory and on site.

Relative humidity generator.

To address variety of applications multiple sensors and rh control modes can be utilized. New series of superior relative humidity rh generators that were deigned for easy interfacing with other analytical instruments that would benefit from carrying out measurements at precisely controlled rh conditions. Orientation does not affect accuracy. Temperature range of 18 c to 35 c.

Controls range of both temperature humidity. The rdsa rotary dilution system is specifically developed and patented to allow the relative humidity generator hg 101 to control the relative humidity with high speed and high stability. The model 1200 mini humidity generator produces accurate humidity values using the fundamental nist proven two pressure principle. Any programmed set point can be reached within three minutes.

Relative humidity range of 5 85 relative humidity 23 c. The 1200 will automatically supply relative humidity dew point frost point and other calculated values for instrument calibration and evaluation as well as precision environmental testing. The humisysxr extended range is a customized version of the humisys family of the superior rh generators. Indeed the response time for a ramp from 20 to 80 is performed in 30 seconds.

The purpose of this instrument is to provide large rh range of humidiied stream from very low to high water vapor concentration to the user defined location. 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. Reaches the level the stability of the measurement is better than 0 2 rh. The concept and design of a miniaturized two pressure humidity generator are presented.

This system automatically generates multipoint profiles as well as manually entered humidity levels while continuously storing and printing system data. Relative humidity accuracy of 1 0. The hygro mini portable humidity generator calibrator is the smallest unit available with variable control for both humidity and temperature. Several modes of rh control are available depending on selection and location of sensors.

Temperature accuracy of 4 c. 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. The model hg 100 relative humidity generator is a compact portable bench top instrument which supplies a specified constant air or nitrogen flow rate with a manually preset relative humidity. Flow rates of usually up to 500cc min are used.

The automatic relative humidity rh generator humisys lf low flow was specifically designed for easy interfacing to other analytical equipment to provide rh controlled stream.
