Trace Moisture Analyzer

  • Series PPM1

The Edgetech Instruments Model PPM1 is a trace moisture analyzer designed specifically for monitoring moisture levels in dew point and PPM units. This trace moisture analyzer utilizes an electro-chemical (P205) sensor in combination with a proprietary semi permeable diffusion membrane. The principle of operation applies the Faraday’s Law of Electrolysis which measures the dissociation current making it a fundamental measurement of the moisture present. The PPM1 is ideally used in relatively clean, dry, inert gas applications. Sensitivity below 1ppm Fast response Long sensor life Low cost Fundamental measurement of moisture content Displays outputs—dew point (CF) and PPM values Air Separators Medical Gas Pharmaceuticals Semiconductor

Portable Dew Point Monitor

  • Series 1500

Finally, a portable Dew Point hygrometer that integrates the accuracy and reliability of the Edgetech Instruments chilled mirror, with the battery life and ruggedness required for field use. Introducing the Model 1500 portable chilled mirror hygrometer. This device incorporates all of the standard features that you’ve become accustomed to from Edgetech Instruments, such as drift-free NIST traceable accuracy, low maintenance, high durability and ease of use, in a system that is ideally suited for the demands of field use. Whether you use the Model 1500 as a field transfer standard, or to spot check your process air dryness or Endo gas dew point, you’ll find this system trouble-free to operate. The Model 1500 is a self contained system; not only is there no field assembly required, there’s no need to carry around a myriad of individual components such as control boxes, sensors, cables, pumps, and power cords. Simply attach the sample line, adjust the flow (with the integral flow meter) and turn on the power. Within minutes you’ll be collecting field dew point data with the same chilled mirror accuracy of a lab standard hygrometer. And with a nominal battery life of 12 hours, you will be able to collect for the entire shift or spot check your processes for several days.
