The DPM-99 is a complete medical air dew/frost point monitoring and alarm system consisting of a chilled mirror hygrometer with LED display plus audible and visible alarm functions, all contained in a NEMA-12 enclosure. Using a primary method chilled mirror dew/frost point sensor, it is the drift-free alternative, meeting Level 1 and Level 2 requirements of the NFPA 99 Standard for medical air.

Other types of dew/frost point sensors, due to inherent drift, require recalibration at regular intervals to remain within their accuracy specifications. The chilled mirror dew/frost point sensor of the DPM-99 is a primary method, drift free device, with accuracy traceable to NIST. Its Automatic Balance Control (ABC) cycle keeps the sensor’s operation in top condition without the need for regular maintenance or periodic calibration.

Safety is the foundation of the Edgetech Instruments DPM-99 Medical Gas Dew Point Monitor. It features very high accuracy and sensitivity, fast response, failsafe alarm functions and analog outputs. Its ruggedized metal enclosure protects against electrical interference and environmental shock. An uninterruptable backup power supply is optional.
