TecWeld Oxygen and Carbon Dioxide Weld Purge Monitor

The TecPen Oxygen and Carbon Dioxide Weld Purge Monitor is designed to provide accurate measurements down to 0% oxygen and up to 100% carbon dioxide when back purging with argon and CO2 gas mix during welding. This portable O2 and CO2 analyzer will verify that there is no oxygen during argon back purging for TIG welding, or argon CO2 blend for MIG welding. Features: Provides accurate measurements down to 0% O2 Measures CO2 levels up to 100% Prevents welding defects Can be used immediately, does not require warm-up time Data logging capabilities with USB transfer for Quality Control/Inspection Ideal for MIG/TIG welders and industrial applications or environments Models TS-300 - TecWeld 0-2,000ppm Oxygen TS-302 - TecWeld O2 + CO2 Weld Purge Monitor Specifications Oxygen Sensor Measurement Range: 0-2,000ppm Accuracy @ 0-0.5%: ± 2%Mev** Accuracy @ 0.5-2.5%: ±3% Mv* Accuracy @ 2.5-5%: ±5% Mv* Resolution: 1ppm Response time at 25°C/ 77°F: <150ms Pump flow: 400mL/min.
