Add a digital temperature readout anywhere, almost instantly. The RT8101 is completely solar powered so no power connections are required and no battery changes. The big digits are easily seen from across the room. Replace old dial thermometers on fridges, walk-ins, display cases, storage rooms, incubators, and other equipment. Locate a temperature readout where you didn’t have one before, without installation headaches.

We’ve also added a couple great features not found on other panel meters. The Min/Max button recalls the highest and lowest temperature since your last reset – perfect for cold storage of food or pharmaceuticals. The °C/°F button gives you a quick conversion without using a calculator.

The RT8101 features an internal sensor. Choose this model to monitor ambient temperature where you mount the unit. Great for room temperatures. The low profile case design looks great next to light switches or thermostats.

The RT8101E comes with a remote probe. Use this model when you want to read the temperature of a fridge or chamber from the outside. The probe tip is molded over the sensor so it is liquid tight and can be immersed in fluids, soil, food, etc…

Both models come with a stick-on hook and loop fastener for mounting. Or you can use a more permanent double-sided tape or adhesive of your own. OEM quantity pricing is available for equipment makers or volume users. Our logo is on the back of the unit and we’ve given the RT8101 a simple, professional look so you can make a clean install to your own panel and it will look like it belongs there.

Great for food storage, industrial use, laboratories, pharmaceutical storage or room temperatures.
