PC110x Operation
The CHEMTROL® PC110x controller operates like a computer, featuring an LCD screen and easy access to all menus and sub-menus. The front panel keypad allows smooth navigation through menus, letting users move between options and enter or exit sub-menus with ease.
The keypad also makes it simple to adjust operating functions, including sensor calibration, control set-points, alarm levels, and feed programs.
Remote Monitoring & Control
Our range of programmable controllers all have remote access capability, so you can control and monitor your facility 24/7.
With the remote operation function any number of facilities can be controlled and monitored from your computer, or via our mobile App. From a computer simply login directly via your browser using our web-server where the controller display is mirrored on your computer.
True duplex operation that allows real-time control and troubleshooting of all operating functions, including status reports, trend graphs and automatic alerts by email or text messages. You can also access and control your controller via our dedicated app, available for Android and Apple devices.
In terms of connecting your controller, this can be achieved via a wired Ethernet cable, WIFI signal, or by using a wireless connection with a compatible 4G or 5G router.
