Relative Humidity Generator

The model 1200 mini humidity generator produces accurate humidity values using the fundamental nist proven two pressure principle.

Relative humidity generator.

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. The hg 100 easily integrates 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. Any programmed set point can be reached within three minutes. The concept and design of a miniaturized two pressure humidity generator are presented.

Indeed the response time for a ramp from 20 to 80 is performed in 30 seconds. 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. Temperature accuracy of 4 c. Flow rates of 50 100 200 or 500 cc min are available at the same cost.

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 accuracy of 1 0. Orientation does not affect accuracy. Controls range of both temperature humidity.

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. Reaches the level the stability of the measurement is better than 0 2 rh. To address variety of applications multiple sensors and rh control modes can be utilized. 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.

This system automatically generates multipoint profiles as well as manually entered humidity levels while continuously storing and printing system data. Flow rates of usually up to 500cc min are used. This unit was designed for field calibration. The hygro mini portable humidity generator calibrator is the smallest unit available with variable control for both humidity and temperature.

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. 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 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. Temperature range of 18 c to 35 c.

Several modes of rh control are available depending on selection and location of sensors.
