The most accurate threaded thermometers we sell, these come with a calibration certificate traceable to NIST that states they’ve passed a test to fall within ±0.5° F accuracy.
Adjustable thermometers have a stem that pivots 180° and a head that rotates 360° for viewing at multiple angles. Tighten the set screws to secure the desired angle.

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.
