PDM75 X3 Portable Industrial Duty Hygrometer 00935
The Model PDM75-X3 is portable dewpoint hygrometer that integrates the accuracy and reliability of the Edgetech Instruments chilled mirror sensor with the convenience and ruggedness required for field use. It features drift-free accuracy, NIST traceability, low maintenance, high durability and ease of use in a portable package.
 
The Model PDM75-X3 has all the standard features of the Edgetech Instruments DewMaster Hygrometer, with a modular chilled mirror sensor that is chemically resistant to background gases. Use it as a field transfer standard, to spot check process gas dryness or to check the calibration accuracy of other hygrometers. The Model PDM75-X3 can be configured for positive pressure sample gas or to extract a gas sample using an integrated vacuum pump.
