The REED C-370-NIST is a precision RTD (resistance temperature detector) thermometer covering -100C to 300C (-148F to 572F), designed for applications needing tighter, more stable readings than a typical infrared or thermocouple probe. It works with PT-100, PT-500, and PT-1000 four-wire RTD sensors, has a waterproof IP67 housing, and displays readings on a backlit LCD with min/max/average tracking. This NIST-traceable version includes a calibration certificate, supporting food-service and other regulated environments where verified accuracy is required.
