User attaches electrode to meter and uses screwdriver to adjust meter to display 20.9% (air) or to any gas of known concentration. Operating on single 9 V battery, meter features 0.5 in. high LCD, low battery indicator, and automatic temperature compensation from 0–40Â°C.
Original Press Release:
Model 630 Atmospheric Oxygen Meter
The Model 630 measures atmospheric oxygen from 0-100%. Its unique galvanic electrode has an expected life of 3 to 5 years. The electrode is not affected by hydrogen sulfide (H2S) or carbon dioxide (CO2) The maintenance-free electrode eliminates problems associated with electrodes requiring membrane replacements and filling solution changes.
Easy to operate, the Model 630 has only one control knob with two positions: OFF and %. Calibration is quick and easy. Simply attach the electrode to the meter and use a small screwdriver to adjust the meter to the display 20.9% (air) or to any gas of known concentration. The screwdriver adjustment eliminates any chance the Model 630's calibrations will be accidentally disturbed.
The instrument is sold in a kit which includes the meter, an electrode with a 5 ft. cable length, instructions, battery and carrying case. Electrodes with custom cable lengths are available upon request
