The Matheson Model 8068 is a universal gas leak detector specially designed to locate and measure a wide variety of gas leaks. It sees widespread use throughout industrial, laboratory, medical and research applications.

Calibration data for 30 gases are stored in memory. The 8068 device uses thermal conductivity to detect gases. The detected signal is displayed on a color LCD Display that includes an audible sounder, LED indicator, and intuitive keypad. The 8068 is equipped with sensitivity ranges of high, medium, and low, and the instrument will zero on start-up. Also included is a unique peak-hold function which retains the highest leak rate detected as the probe is passed through the suspect leak area.

Gases Detected

The 8068 continuously draws sample into the detector. A micro volume thermistor conductivity cell, located in the front end of the unit for fast response times, detects any gas having a different thermal conductivity than the ambient atmosphere. Target gases can be easily selected in the main menu.
