Rugged Fiber Optic Temperature Monitor.


Rugged design, designed for reliability, multichannel fiber optic temperature monitor for Industrial and Laboratory applications. The Rugged Monitoring L201 is a compact design, designed for reliability to operate in extreme EMI, RFI, Microwave and high voltage environments. The L201 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 Industrial and Laboratory applications. 

The L201 has a measuring range from -271 °C to +300 °C. The system offers complete immunity to RFI, EMI, microwave radiation, and High Voltages making it an optimal choice for environments where the limitations of conventional temperature sensors/ monitors impact usage in extreme conditions. The system is based on proven GaAs technology and designed for Plug and Play operation.
