Dual Channel Oxygen Amplifier for Harvard/Instech Oxygen Monitoring System

This amplifier generates the potential that operates our standard electrodes 56-5002 and also converts the nanoamp electrode current into a voltage to measure pO2. It contains two independent channels, each with gain and zero offset controls and analog outputs. A 3.5-digit LED display can be set with a selector switch to display either channel or the difference between the two. The amplifier measures, H x W x D, 10.8 x 26.7 x 22.2 cm (4.25 x 10.5 x 8.75 in) and weighs 1.6 kg (3.5 lbs). It operates on 120 V AC current, but can set for 220 V operation at the factory.
