ETS-05 Electronic Thermostat

nVent RAYCHEM ETS-05 hazardous area electronic surface sensing thermostats provide accurate temperature control for heating cables. The ETS-05 is available as an Ambient sensing thermostat and as line sensing thermostat. The ETS-05-L is adjustable to

 199 °C, ETS-05-H up to 499 °C. ETS-05 has a LED to indicate status of the thermostat, heating cable and sensor. The ETS-05 is available with an alarm relay for remote monitoring.
