The PRTXB and PRTXAL Digital Temperature Gages include a precision RTD Sensor in a rugged 316 SS sheath. The front keypad is used for power on/off, min/max functions, selection of deg F, C or K, auto shutoff times (forbattery models), calibration and configuration options. User-defined pass codes for configuration and calibration to prevent unauthorized changes.
