CNYST Temperature Calibrator Multifunction Temperature Process Calibrator with Accuracy 0.05% Source DC MV 0mV～100mV Resistance 0～3200Ω RTD Pt100 Pt1000 Cu50 Cu100 TC E J K T B R S N IP67 Waterproof Grade
Introduction:
This temperature calibrator is a high-precision, high-resolution, and highly reliable handheld calibration instrument that integrates the measurement and simulation of resistance temperature detectors (RTDs) and thermocouples with the output and measurement of electrical parameters such as voltage, millivolts, and resistance. It features a large, high-brightness backlit display, is easy to operate, has a rugged construction, and is compact, lightweight, and cost-effective.
Function:
- Measures temperatures from thermocouple and RTD outputs;
- Simulates thermocouple and RTD outputs;
- Both thermocouple measurement and output support automatic and manual cold-junction temperature compensation;
- Accuracy: 0.05%;
-
Offers manual step, automatic step, 0–100% step, and slope output functions;
- Features a white LED backlight with manual backlight adjustment and automatic power-off, making it suitable for field use;
- Unique automatic recognition of three-wire and four-wire connection configurations;
- Battery compartment cover for easy battery replacement;
