Basic Purge Monitor (BPM): Portable and simple to use
Portable for almost use anywhere, the Basic Purge Monitor is compact, battery-powered and handheld. Furthermore, the straightforward push-button operation of this entry-level purge monitor offers high accuracy and reliability, all at a competitive price.
Optical Cell Technology
The simple optical cell technology offers reliability and accuracy and extremely long life. Unlike other equally priced equipment, the optical cell technology fitted in the Basic Purge Monitor is non-depleting. An internal pump provides precise and consistent gas sampling readings. The BPM displays Oxygen levels from ambient (20.90%) down to 0.01%.
The basic 4 x 20-character monochrome LCD screen displays both the Oxygen data and the remaining battery level.

Further purging products available
The HPM-01 uses a simple non-depleting optical oxygen cell. The HPM-02 combines the optical cell technology from the HPM-01 with a miniature, low power Zirconia sensor. Both the HPM-01 and HPM-02 have onboard data-logging.
With a 5.7-inch LCD, the GPM also provides an onboard printout of the logged data. Options include an inline hygrometer sensor for measuring moisture content in purge gas and an external warning beacon system.
Finally, the Gas Purge Automatic Flow Control System, designed for use with the GPM, offers full automation for gas purging activities. Easily programmed to give three flow rates (high, mid and low). Control of purge gas flow according to the Oxygen level provides quick, accurate and efficient purging. When only the optimum amount of gas is used for the purging process this ultimately results in cost savings!
