Product Features:

1. Independent channel synchronous acquisition

Each channel of DTZ-300BW Wireless Measurement Instrument adopts an independent high-precision AD chip, and no channel switching is required during the measurement process, which effectively eliminates the measurement error introduced in the channel switching process. Synchronous data acquisition at the second speed greatly improves the time synchronization between the measured values of each channel on the premise of ensuring the measurement accuracy.

2. Flexible channel configuration

Each channel of Multichannel Measurement Instrument supports four input modes: thermocouple, thermal resistance, humidity sensor and (0~1)V analog. Each channel can be understood as a universal channel, and only simple configuration of the channel is required. You can flexibly switch between different input modes, and the channel configuration can be stored as a configuration file, which is convenient for subsequent recall and modification.

3. High precision thermocouple cold junction

Each channel of DTZ-300BW Measurement Instrument uses an independent high-precision digital temperature sensor as the cold junction compensation sensor. The distance between the cold junction temperature measurement point and the thermocouple wiring point is less than 20mm. At the same time, combined with a good temperature average design, it can be used for each thermocouple measurement channel. Provides reference compensation with an accuracy better than 0.15°C.

4. Meet the AMS2750E specification

The AMS2750E specification puts forward high measurement requirements for the accuracy of inspection equipment. Through the optimized design of the analog input channel and the temperature measurement of the reference terminal, the thermocouple measurement accuracy and the difference between the channels of the DTZ-300BW wireless temperature humidity acquisition have been effectively improved, which can meet the stringent requirements of the AMS2750E specification for electrical measuring instruments.

5. Statistical data analysis

Each channel of Measurement Instrument has independent curve display and data analysis functions, and users can view the statistical data such as the maximum value, minimum value, and volatility of the measurement data in real time. After starting the measurement, the measurement data is automatically saved to the file, and the user can browse and analyze the historical data at any time.

6. Data encryption

It can provide encryption algorithm support, encrypt data files, and meet the special requirements for data security in special industries such as national defense and military industries.

7. Wireless LAN

The DTZ-300BW temperature humidity acquisition can be connected to a tablet or laptop through a 2.4G wireless network, and multiple inspection instruments can be used at the same time for temperature field testing, which effectively improves work efficiency.

8. Large capacity storage

The DTZ-300BW temperature humidity measurement instrument has a built-in 8g large-capacity memory, and also supports the U disk storage function, which can easily import the input into the U disk. In stand-alone operation, the inspection data can be stored in the built-in memory, and the stored data can be browsed or processed by general tool software such as Excel, or imported into special software for data analysis, report generation and certificate output. Large-capacity memory solves the problem of data security and non-volatility, and enhances the reliability of data.

9. Rich and friendly human-computer interaction functions

The DTZ-300BW intelligent temperature humidity acquisition adopts a 7-inch touch screen design and provides a rich and friendly human-computer interaction interface.
