High-temperature pyrometer with fibre optics sensing head. Sensing head may be used in ambient temperatures up to 200°C. Short wavelength for improved accuracy when measuring metals and reflective surfaces. Touch screen interface for indication, graphing, configuration and data logging to MicroUSD card. 4-20 mA or RS485 Modbus output. Two alarm relays on all models. For sensors with Modbus output, the address is set to 1 as standard. For reflective metals, high temperature targets and viewing through glass.
