Foodservice: Ditch Clipboards for Good

Why: Foodservice Hinges on Accuracy
Business relies on rushed humans who prep, plate, serve, and manually checking food temps.

 Misread or incorrectly written temps on an old clipboard can lead to improperly prepared food and illness.

What’s Next: the IoT Food Thermometer
Monnit’s ALTA Wireless Food Probe thermometer takes the temperature of cooked or refrigerated food from -50°C to 260°C (-58°F to 500°F). This Internet of Things digital thermometer clearly displays temperatures, provides this data with bank-grade security, and transmits it up to 1,200 ft. Data can then be automatically logged in iMonnit software, creating a data trail as ingredients are processed and prepared.

 This turnkey and highly portable digital Food Probe is housed in a water-resistant IP67 case. The sensor includes: removable curved* needle-style probe, pop-out grip, and wall mount.

How it Benefits You: Modernized Food Safety
Monnit’s ergonomic food temperature probe modernizes food prep—operators can replace outdated clipboards with remote monitoring and automated data logging.

 Get the reliability and repeatability that humans can’t match in your commercial kitchen.

Data logging with this food temperature monitoring solution helps obtain and maintain compliance with CFR21 part 11 and the FDA’s Food Safety Modernization Act. This wireless food thermometer also beefs up HACCP and quality initiatives.

Where’s it Used: Anywhere Food is Made & Served
Monnit’s Food Probe supports food production, restaurants, cafés, bars, and food trucks because food safety matters everywhere. Track food temps for dine-in service, curbside delivery, drive-through, or carry-out.

The Food Probe was developed for a fast-food group seeking improved chain-wide quality and consistency. Test chefs also wanted to spot-check processes for creating innovative recipes.
