The TUS40-20 is a terminal unit for monitoring and setting the URx20xx sensors and consists of:
- the TUS40 handheld terminal
- the UIC20 junction box
- the 3m long CBL01 coiled cable
the two units communicate through a dedicated master protocol.
The TUS40-20 terminal unit is necessary when a mobile monitoring system is required and/or for different settings of the gas detection threshold limit values from the ones that can be set using the DIP switch; it is also necessary for recalibrating sensors if standard factory calibration gas cylinders are not used.
