This company has attained CCSAUS certification for its XTP601 Oxygen Analyzer, making it approved for use in hazardous areas in the U.S. and Canada. The instrument already carries certification from ATEX and IEC Ex. The XTP601 uses thermo-paramagnetic measurement technology to make accurate and stable measurement of O2 in background gases, such as H2, N2 and CO2, over ranges from 0–1% and 0–25%. Housed in a flame- and explosion-proof enclosure, the instrument is available in three versions: a blind transmitter, a unit with status LEDs or a full-display unit. All three versions are supplied with two 4–20-mA outputs, two concentration alarms, Modbus RTU over RS485 protocol and application software. — Michell Instruments, Ely, U.K.
