Remote-Reading Panel-Mount Thermometers




Monitor the temperature of difficult-to-access system components from a distance. These thermometers have either a bulb or a probe, so the dial can be mounted away from your system.
Thermometers that meet NSF standards are for use in food processing and preparation areas.

Clip-On Freezer Thermometers
Monitor temperature in freezers, coolers, and storage areas with these thermometers.
The indicating color changes to red if the temperature gets too high for thermometers with a color changing temperature zone indicator, alerting you to make adjustments. Thermometers with a scale display are filled with mercury-free fluid for a quick response time. Thermometers with a dial or digital display make it easier to see small temperature fluctuations than those with a scale display.
NSF/ANSI 2 thermometers meet standards for food equipment. They show a blue indicating color when the temperature is in the safe zone for food.

Sanitary RTD Probe Transmitters with Digital Display
Check the temperature of liquids in hygienic applications such as food or pharmaceutical lines and tanks. Certified by 3-A to meet sanitary design standards, the parts of these probes that will touch liquid are highly polished to minimize spots where bacteria could grow. They're rated IP67 and IP69K, so they'll withstand temporary submersion as well as the high-pressure, high-temperature washdowns that are common in hygienic cleaning practices. Made of stainless steel, harsh cleaners and sanitizers won't cause them to corrode. They have a flange that will connect to sanitary quick-clamp fittings (also known as tri-clamp fittings); they're easy to connect and remove from your line.
Program these probes with the touch screen, and select one of three colors as a visual alert for events in your process such as irregular or fluctuating temperatures. The head swivels 345° and the face rotates all the way around, so you can mount the sensor at any angle and still see the display. To trigger actions in your process line, connect these probes to remote displays, programmable logic controllers (PLCs), and other control equipment with the M12 plug. These probes meet DIN EN 60751, an industry standard for accuracy. They’re also CE marked, meaning they meet European Union safety standards.
