Designed for food service and processing plants, this affordable meter reads any type K thermocouple. Competing units suffer from hard-to-read digits, poor accuracy, complex operation, cord-wrapping food traps and much higher prices. The slim, easy-to-grip body of our new Therma K is compact and tough enough for commercial kitchens. Accuracy is better than ±0.5°F in food ranges and ±0.7°F over the full range. Each unit includes a calibration certificate with actual test data traceable to National Standards for confidence in your readings. With just one button to press, the Therma K reduces staff training time and errors. Best of all, the price is great!
