To best meet specific application needs, the DT722 relative humidity (RH) and temperature transmitter is available in digital (DT722) and analog (DT722-X18) models. The digital version gives high performance measurement with “excellent” RH accuracy and delivers reliable, consistent and accurate results, even over changing ambient conditions, says the company. The DT722-X18 is an analog through-path measurement device with exceptional mechanical toughness. DT722 transmitters have stainless-steel housings for protection against rough handling or accidental damage, IP65 (NEMA 4) ingress protection and a probe that can withstand temperatures up to 150°C. — Michell Instruments Ltd., Ely, U.K.
