The Rugged Monitoring H201 is a compact design, designed for reliability to operate in extreme EMI, RFI, Microwave and High Voltage environments. The H201 Fiber optic monitor combines reliability and user friendly interface in the monitor and software.  It is a multi-channel fiber optic temperature monitor with precision measurement for Factory Testing, Industrial and Laboratory applications. The H201 has a measuring range from -271 °C to +300 °C. The system is based on proven GaAs technology  and designed for Plug and Play operation. Its immunity to extreme test conditions and harsh environment makes H201 the default choice for temperature testing and measurement.

The H201 is designed to connects to the fiber optic temperature sensors (GaAs technology based) and provide temperature readings on local display. Plug and Play functionality provides the flexibility to interchange sensors without the inconvenience/concerns of calibration. The measured temperature data can also be send to third party datalogger / system through serial communication like RS-485 or analog outputs like 0-10 V / 4-20 mA. The H201 monitor comes with Rugged Connect software which is designed for remote visualization of data, perform analysis and integrate with other Test and Monitoring platforms. Rugged Connect Fiber Optic Software is capable of collecting data from 6 x H201 or other rugged monitoring systems simultaneously. Industry standard drivers available for a quick and easy connect to most popular laboratories software / computing environments. There is a dedicated team of experts available for customizing fiber optic temperature solutions to meet specific customer needs.
