6. External cold end compensation treatment: The temperature and humidity field automatic testing system uses an external four wire PT100 with an accuracy better than 0.2 ℃ as the cold end compensation for the thermocouple measurement channel.

7. Communication method: Ethernet WIFI、4G、RS485

8. Equipped with GPS function, the instrument can quickly pick up information such as unit name, instrument name, manufacturer, calibration date, etc. based on GPS latitude and longitude coordinates.

The 9.4G transmission function can transfer measurement data to the cloud and transmit it in real-time to the PC for display and analysis, and generate certificates and original records.

10. Power supply mode: Built in large capacity lithium battery with a standby time of 12 hours;

11. The instrument comes with environmental temperature, humidity, and atmospheric pressure measurement, which can display the current environmental temperature, humidity, and atmospheric pressure in real time;

12. Dimensions: 192 mm × 136 mm × 45mm

Sensor technical parameters:

1. Temperature measuring platinum resistance specifications: Pt100, measuring wire 5m, temperature measuring range: -60 ℃~300 ℃.

3.3 Probe: PPS, with a diameter of 15mm

3.4 Cable: 5m, temperature resistance -50 ℃~200 ℃

Characteristics:

1. The data collector adopts a 7.0-inch LCD touch screen and a capacitive touch screen to display its configuration and real-time data (including temperature, curve, and test result display modes that can be switched freely).

2. No PC is required at the work site. The multi-channel data collector can independently complete the data collection and storage work, and transmit the test data to the cloud in real time and to the PC for display and analysis, and generate certificates and original records.

3. One host can simultaneously support 2 module combinations for measuring 18 thermal resistors and thermocouples, as well as 8 humidity sensors, which almost meets most application scenarios (can calibrate multiple boxes simultaneously, saving valuable on-site testing time).

4. One host can collect data from 5 modules separately (multiple boxes can be calibrated simultaneously, saving valuable on-site testing time).

5. The sensor connection method adopts a push-pull aviation socket connection, with a contact resistance of less than 0.005 Ω, which is simple, fast, and ensures the reliability and performance indicators of the system connection.

6. Special specifications of sensors can be optionally selected. The company can provide various special specifications of temperature sensors to meet the needs of different occasions.

7. PC software can display real-time temperature and humidity curves for each channel (thermocouple, thermistor). Different channel curves are represented by different colored curves, which can be modified at any time to intuitively reflect the fluctuation of temperature and humidity of the measured object. And record the measured data, which can be exported to Excel at any time as needed, and can be queried and printed at any time.

8. The system meets the technical specifications requirements of the national calibration standard JJF1101-2019. Automatically calculate temperature and humidity deviation, uniformity, and fluctuation, generate original records that meet the requirements of national laboratory accreditation, and provide templates and interfaces for modifying original records, calibration/verification certificates for easy modification. Automatically perform reference compensation and correction of sensor calibration data.
