This oxygen analyser panel is built around the Eaton MTL G1010 Mark II galvanic oxygen analyser and shows oxygen in ppm. It includes an Influx flowmeter and calibration selector switches, and is typically used to monitor oxygen in nitrogen generators and inert gas systems on ships. SM MARINE SERVICE™ (https://www.smmarineservice.com/) supplies oxygen analysers and gas analyser spares worldwide.
The MTL G1010 range uses a galvanic oxygen cell to measure oxygen from ppm to percent levels. On this panel the sample gas passes through the flowmeter to the sensor; the "SELECTION CAL – SAMPLE" switch selects calibration gas or sample, and the "CALIBRATION SPAN – ZERO" switch selects span or zero gas. The G1010 displays the oxygen value, has two alarm LEDs and keys for editing and calibration.

Safety notes: isolate power before opening the panel. Nitrogen and inert gas can cause asphyxiation – vent sample gas safely and work with gas detection in place.
SM MARINE SERVICE™ supplies MTL G1010 analysers and complete oxygen analyser panels; availability subject to confirmation. Please send the analyser rear label photo (model code, cell type, range, supply), vessel name / IMO and delivery port. We ship worldwide.
The G1010 is a simple, stable oxygen analyser widely fitted to nitrogen and inert gas systems; a same-type replacement keeps panel cut-outs, wiring and calibration procedures unchanged.
