The thermal calibrator is mainly used for the calibration and maintenance of industrial field thermal instruments and systems. The thermal calibrator has perfect functions and practicality, and is easy to operate. The collection of thermal calibrator adopts single chip microcomputer as CPU, and integrates new large-scale digital conversion integrated circuit and large-screen liquid crystal display technology. It has output, measurement, manual and 24v DC power distribution functions, and the four functions can work at the same time, displaying the output and measurement values ​​and the corresponding ITS-90 standard values ​​(thermal resistance and thermocouple) on the same screen. The thermal calibrator is equipped with a large-capacity rechargeable battery, which is easy to carry and can easily complete the maintenance and calibration of industrial field thermal instruments (sensors, transmitters, display instruments, and control systems).

 The thermal calibrator has the following features:

Compact, easy to carry and hold.

Sturdy and reliable, the support frame and hook holes on the back are suitable for field use.

Large display, measurement and output can be displayed at the same time.

Measurement of voltage, current and resistance and output of voltage and current.

8 kinds of thermocouples (K, E, T, J, S, R, N, B) measurement and output, 2 kinds of thermal resistance (PT100, Cu50) measurement.

The measurement output of thermocouple and thermal resistance in thermal power engineering is correspondingly displayed by ITS-90 international standard millivolt and resistance value.

Voltage and current measurements can display percentages.

Thermocouple measurement and output with automatic or manual compensation.

There are many ways to input and output values.

The thermal calibrator can quickly check the resistance value and temperature value, millivolt value and temperature value.

The thermal calibrator has a built-in large-capacity rechargeable battery, which can work continuously for 5 to 7 hours (related to working conditions).

Large-screen LCD display with backlight display and Chinese menu operation.

You can control the key sound and backlight, and you can keep the state after the last setting every time you turn it on.

Precautions in the use of thermal calibrator:

1. Do not apply more than the rated voltage indicated on the calibrator between the terminals or between the terminals and the ground; the maximum voltage between the terminals is 30 VDC;

2. Before use, measure the known voltage to confirm that the calibrator works normally;

3. Please follow the safety steps of all equipment;

4. When one end of the test lead is inserted into the current jack, do not touch the voltage source with the probe at the other end;

5. Do not use a damaged calibrator; before use, check whether the calibrator's casing is damaged or missing plastic parts; 6. Pay special attention to whether there is insulation around the connector;

7. Select the correct function and range file according to the measurement requirements;

8. The calibrator is powered by a lithium battery. Please manage the power supply according to the charging and discharging characteristics of the lithium battery to prolong the service life of the battery.

9. Make sure the battery power is sufficient before use. If the battery is too low, it should be used after charging.

10. Check the test wire for damage or exposed metal; if damaged, replace the damaged test wire before use; check if the test wire is conductive;

1. When using the probe, do not touch the metal contact of the probe with your fingers; your fingers should be placed behind the probe finger protector.
