    Metal- and X-Ray-Detectable

    Thermometers

    Non-Metal and X-Ray

    Detectable

    Wall-Mount Holder

    For easier viewing than dial thermometers for food and beverage, these thermometers show readings on an LCD.
    Metal Detectable and X-Ray Detectable—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.
    Food Industry Standard—All meet standards for use in food-processing environments.
