Home Gas Analyzer Indonesia Model 321 Portable O2 Process Analyzer (NOVA)
Model 321 Portable O2 Process Analyzer (NOVA)

A rechargeable ‘gel cell’ battery provides enough power for the pump and electronics for about 20 hours of continuous operation. The analyzer may still be operated while it is being charged. A red LED indicates when to recharge the analyzer and a green LED indicates that it is receiving recharging power. The battery recharger is included with the analyzer. The detected O2 is displayed on an LCD digital meter that has a switchable backlight for use in dark areas. The analyzer is supplied with a 12ft. sample hose and either a sample pump or pressure regulator.

APPLICATIONS
