CO2Meter.com has introduced a 25 percent oxygen level sensor designed to drastically lower maintenance costs by simplifying the calibration process. The TR250Z:
- Can be calibrated in-situ with the press of a button and with any gas of a known oxygen level — even fresh air. The procedure requires no knowledge of gas sensing, and is verified using the internal LED display. This drastically reduces labor costs and makes it more likely that regular calibration will occur.
- Supports both the industry-standard 4-20mA protocol used in process controllers and RS-485 for advanced applications where precise transmission of sensor readings is required.
