The Shinyei DewTracer mini CRDS-H2O is the world’s smallest and most innovative Cavity Ring-Down Spectroscopy (CRDS) trace moisture analyzer. It can measure trace moisture in the range of 12 ppbv ~ 20 ppmv (-100 … -55 °C frost point) with high speed, high accuracy and long-term reliability.
Features
Accurate and stable trace moisture measurement over the range 12 ppbv ~ 20 ppmv (-100…- 55 °C frost point )
The measurement accuracy and stability of the Shinyei DewTracer mini CRDS-H2O is verified by comparative evaluation with AIST primary standards.
Fast response to changes in amount of trace moisture
DewTracer mini CRDS-H2O sensor has small cavity volume which means that gases are purged quickly and its measurement can rapidly trace sudden changes in trace moisture with SHINYEI unique spectral analysis.
Measurements unaffected by corrosive gases or other components
CRDS sensor measures an amount of trace moisture in the sample gas without contact and can also measure moisture in corrosive gases.
No sensor drift and long-term reliability measurements
CRDS trace moisture analyser provides long-term highly reliable trace moisture measurements because the sensor does not drift as seen with adsorption/desorption type sensors and its measurement method uses an absolute measurement method that does not require calibration curves.
Compact size for installation flexibility
The sensor unit is small (H165 x W150 x D300 mm) and can be installed in 19-inch racks (3U).
Sensor unit and monitor unit
Sensor unit and monitor unit can be separated and it provides the best installation options can be selectable for applications and locations. PC with bundled software also can be used instead of monitor unit to operate the sensor unit and manage measurements.
Monitor unit with 5-inch touch panel colour display
DewTracer includes a monitor unit with 5-inch colour touch panel for start/stop of measurements, changing settings, display measurements and trend graphs. It also has screen lock to prevent misuse, a status function to check the instrument’s operating status, and an alarm feature to set a threshold value. When a PC is used instead of the monitor unit, the same functions as the monitor unit can be performed with the bundled software.
VCR fittings are used for sample gas IN-OUT. Additional ports for purging the inside the sensor unit with nitrogen in a case of sample gas leakage from the cavity are available.
Selectable output options
Digital (RS-232C), analogue (4 – 20 mA, option), or alarm (MOS FET relay, option) are available.
