A simple nine position rotary switch enables engineers to quickly perform combustion tests, differential pressure tests, let-by/tightness tests, differential temperature tests and CO build-up tests. Exceptionally accurate and stable pressure readings allow difficult tasks such as measuring flue draught and checking the air/fuel ratio valve on high efficiency boilers to be performed with confidence. Each test can be printed or logged using just one button. Large four line backlit display. Measures O2, CO, temperature and pressure. Calculates CO2, CO/CO2 ratio, excess air and efficiency. Multi-fuel: natural gas, propane, butane, LPG, 28//35 sec oils, wood pellets. High accuracy differential manometer. Differential thermometer for flow / return /î”T. One button print and log facility. Customised reports for combustion, pressure, let-by/tightness, temperature and CO build-up. Infra-red output to the thermal paper printer. Torch light. Connection for optional gas leak detector. Designed to meet BS7927, EN 50379 and BS7967. Battery life typically 12+ hours from full charge Gases Detected = Carbon Dioxide, Carbon Monoxide, Carbon Monoxide/Carbon Dioxide Ratio, Oxygen Best Carbon Monoxide Accuracy = ±10ppm Carbon Monoxide Resolution = 1ppm Best Carbon Dioxide Accuracy = ±0.3% Carbon Dioxide Resolution = 0.1% Best Oxygen Level Accuracy = ±0.2% Oxygen Level Resolution = 0.1% Best Gas Pressure Accuracy = ±0.005mbar Gas Pressure Resolution = 0.001mbar Best Temperature Measurement Accuracy = ±1 °C
