Product Features
1. 0.1 second / channel inspection speed
Whether data acquisition for each channel can be completed in the shortest possible time is a key technical parameter of the verification instrument. The shorter the time spent on acquisition, the smaller the measurement error caused by the temperature stabilities of the space. During the TC acquisition process, the device can perform data acquisition at a speed of 0.1 S/channel under the premise of ensuring the accuracy of 0.01% level. In the RTD acquisition mode, data acquisition can be performed at a speed of 0.5 S /channel.
2. Flexible Wiring
The device adopts a standard connector to connect the TC/ RTD sensor. It uses an aviation plug to connect to the sensor to make connection of the sensor simpler and faster under the premise of guaranteed connection reliability and performance indexes.
3. Professional Thermocouple Reference Junction Compensation
The device has a unique reference junction compensation design. The temperature equalizer made of aluminum alloy combined with the internal high-precision digital temperature sensor can provide a compensation with an accuracy better than 0.2℃ to the measuring channel of the TC.
4. Thermocouple measurement accuracy meets the requirements of AMS2750E specifications
The AMS2750E specifications place high demands on the accuracy of the acquisitors. Through the optimized design of the electric measurement and the reference junction,the accuracy of the TC measurement of the device and the difference between channels are optimized by significantly, which can fully meet the demanding requirements of AMS2750E specifications.
5. Optional dry -wet bulb method to measure humidity
Commonly used humidity transmitters have many usage restrictions for continuous operations in high humidity environments. PR203/PR205 series acquisitor can measure the humidity by using the dry-wet bulb method with a simple configuration, and measure the high humidity environment for a long time.
6. Wireless communication function
Through a 2.4G wireless network, a tablet or a notebook, up to ten devices can be connected at the same time. Multiple acquisition instruments can be used at the same time to test the temperature field, which effectively improves the working efficiency. In addition, when testing a sealed device such as an infant incubator, the acquisition instrument can be placed inside the device under test, simplifying the wiring process.
7. Support for Data Storage
The instrument supports the USB disk storage function. It can store the acquisition data in the USB disk during operation. The storage data can be saved as CSV format and can also be imported into special software for data analysis and report / certificate export. In addition, in order to solve the security, non-volatile issues of the acquisition data, PR203 series has built-in large flash memories, when working with a USB disk, the data will be double backed up to further enhance data security.
8. Channel expansion capability
The PR203/PR205 series acquisition instrument supports the USB disk storage function. It can store the acquisition data in the USB disk during operation. The storage data can be saved as CSV format and can also be imported into special software for data analysis and report / certificate export. In addition, in order to solve the security, non-volatile issues of the acquisition data, PR203 series has built-in large flash memories, when working with a USB disk, the data will be double backed up to further enhance data security.
9. Closed design, compact and portable
The PR205 series adopts a closed design and the safety protection level reaches IP64. The device can work in a dusty and harsh environment such as a workshop for a long time. Its weight and volume are much smaller than that of desktop products of the same class.
10. Statistics and data analysis functions
By using more advanced MCU and RAM, PR203 series has a more complete data statistics function than PR205 series . Each channel has independent curves and data quality analysis, and may provide a reliable basis for the analysis of the pass or fail of the test channel.
11. Powerful human interface
The human interface interface consisting of the touch screen and mechanical buttons can not only provide convenient operations, but also meet the requirements for reliability in the actual work process. PR203/PR205 series has an operation interface with enriched content, and the operable content includes: channel setting,acquisition setting, system setting, curve drawing, calibration, etc., and the data acquisition can be independently completed without any other peripherals at the test field.
