2 O is a gas detector for continuous monitoring of nitrous oxide (dinitrogen monoxide) in the ambient air. It offers all benefits of fail-safe IR measurement technology for applications in rough environments. The transmitter uses microprocessor technology to convert the signal to a 4 to 20-mA analog output. The unit is designed for one-man calibration and offers a variety of diagnostics and self test features. The configuration and calibration of the transmitter is menu guided and easy to perform, using the built-in push buttons. Features and Benefits - Minimum maintenance required - Fast and accurate response- Linear output signal nearly independentof temperature and humidity- Adjustable measurement ranges between0 to 300 ppm and 0 to 1000 ppm- Robust splash-water proof housing low cross-sensitivities to other gases suchas NO, NO
