Detailed introduction
Thermocouple check device for industry

Model: SN / WJT-2A

WJT-2A thermocouple calibration device is specially used for calibration work, suitable for: nickel-chromium-nickel-silicon (K) nickel-chromium-silicon (N) nickel-chromium-copper nickel (constantan) (E) Calibration and indexing of thermocouples.
The device has a more advanced electrical measurement system and temperature control system, which has reliable verification data and stable performance.

The comparison method is adopted for verification: that is, the second-class standard platinum-rhodium 10-platinum thermocouple is directly compared with the calibrated thermocouple for verification and indexing.

The complete set of equipment includes second-class standard platinum-rhodium 10-platinum thermocouple, operation table, and thermocouple tubular verification furnace.

The operation console consists of a temperature control system and an electrical measurement system.

Temperature control system includes: XMTF intelligent digital regulator, temperature control thermocouple, solid state relay, etc.

The electrical measurement system includes: PZ150A DC digital voltmeter and SY821 transfer switch.

This device is suitable for provincial, city, and county-level legal metrological technical institutions, industrial and mining enterprises, and scientific research units.
