Indicators & Controllers
A bright digital display shows the exact temperature of your fridge, freezer or cold room at a glance. The controller then does the hard work, switching cooling on and off to keep the temperature right where you set it, every hour of the day.
Digital Temperature Indicator Controller
A panel-mounted digital indicator that shows the live temperature of your fridge, freezer, cold room or process in bright red LED digits. With up to two programmable set points and relay outputs, it also switches your cooling or heating equipment on and off keeping the temperature exactly where you want it.

- Frequently Asked Questions
Which product should I choose panel indicator controller or handheld indicator?
Choose the panel indicator controller for a fixed fridge, cold room or machine where you need continuous display and automatic control. Choose the handheld indicator for quick spot checks across many locations.
What is the difference between an indicator and a controller?
An indicator only shows the temperature. A controller also switches your cooling or heating equipment on and off to keep it at the value you set. The panel model does both.
Should I choose single or dual display?
Single display shows only the live temperature. Dual display shows the live temperature and set point together useful for control applications.
Can the panel model trigger an alarm or hooter?
Yes. Set high or low set points and the relay output can switch an external hooter, lamp or alarm when the limit is crossed.
