Single Channel Viewsmart 2150/2050 LED Alarm Controller
Brand: R.C. Systems Co.The ViewSmart 2150/2050 2-Channel Controller provides simultaneous display and alarm functions for two monitored variables, and includes two large and easy to read LED displays.
Easy to configure and user friendly, the ViewSmart 2150/2050 can function as a critical alarm controller for toxic gases, combustible gases, vibration, tank levels and other process values.
As part of the ZoneProtector System Solution, the ViewSmart 2150/2050 may be equipped with up to two locally mounted SenSmart 1000 series detectors.
A Sample Draw Pump is also available making the ZoneProtector the ideal solution for wastewater treatment plants, battery charging rooms, anallyzer shelters, parking garages, well heads and many others.
