What sort of sensor is used? — A unique solid-state, long-life sensor, offering lower costs and high precision down to 10 ppm.
What is the intended application? — This monitor is primarily for welding high-quality joints in titanium, duplex, and other high-spec stainless steel to prevent coking, oxidation, and discolouration. It is ideal where the inlet for the monitor sensor can be connected to a constant flow of exhausting weld purge gas.
Why isn't it fitted with a pump? — Most welding applications have an adequate flow of weld purge gas that can be exhausted over the measuring sensor.
How long are the purging hoses supplied? — The red tube is 40 cm long, and the green tube is 1 meter long.
Is it sensitive to electrical disturbances? — Each instrument has shielding to prevent most forms of interference. Quality Control Tests and Inspection criteria are designed to account for as many variables as possible, making electrical interference extremely rare.
My company needs a Calibration Certificate for all instruments once a year. How do I obtain one? — Contact us for pricing and arrangements. Calibration and certification are completed within a few days.
Can it detect oxygen levels in pipes pre-heated to 300°C (575°F)? — PurgEye® Weld Purge Monitors® should not be exposed to gas above 50°C (122°F). Contact us for information on exhaust purge gas cooling methods.
Can Weld Purge Monitors® only be used when purging with argon? — The PurgEye® monitors measure oxygen levels within any gas, not just inert gases. They can be used with argon, helium, nitrogen, and nitrogen/hydrogen mixes.
