Industrial Grade Chilled Mirror Hygrometer
Fast-responding chilled mirror hygrometer delivering drift-free, high-accuracy dew point measurement for industrial humidity control.
The Michell Optidew is an industrial-grade chilled mirror hygrometer built on the latest chilled mirror sensing technology, offering fast dynamic response to fluctuating humidity conditions. Its hybrid sensor delivers dew point accuracy of ±0.15°C and temperature accuracy of ±0.1°C across a wide -40 to +120°C dew point range, making it suitable for both industrial process control and precision laboratory use. Flexible communication options, including Modbus TCP over Ethernet, simplify integration into plant networks, while an optional pressure transmitter enables direct calculation of ppmV and g/kg moisture content. Available in bench top, wall mount, and transmitter configurations to suit diverse installation requirements.
