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.

For dairy, food, and beverage applications that require frequent cleaning, these 3-A certified thermometers have a sanitary quick-clamp connection for easy removal.

For easier viewing than dial thermometers for food and beverage, these thermometers show readings on an LCD. All meet standards for use in food-processing environments.

Metal- and X-ray-detectable thermometers contain metal and chemical additives, so they can be caught if they fall into your line, helping you comply with Hazard Analysis Critical Control Point (HACCP) programs. They’re bright blue, so they’re easily spotted and removed. The probe opens 180° to take temperatures at multiple angles. Unfold the probe to turn thermometers on, and fold it back into the handle for protection when not in use.

Optional wall-mount holders protect and help you keep track of metal- and X-ray detectable thermometers. Holders are also metal- and X-ray detectable, as well as bright blue.

For use in food processing and preparation applications, these thermometers meet NSF/ANSI standards.

For use in food-processing applications, this thermometer meets NSF/ANSI standards and includes a thermocouple probe with a pointed tip to pierce dense meats and frozen foods. The housing meets IP07 for protection from temporary submersion.

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.
