Product

• Acquisition speed of 0.1s / channel

Under the premise of ensuring the accuracy of 0.01%, data acquisition can be performed at a speed of 0.1 S/channel. In the RTD acquisition mode, data acquisition can be performed at a speed of 0.5 S /channel.

• Sensor correction function

The data of all temperature and humidity channels can be automatically corrected according to the existing customer configuration. In addition, the PR203 series acquisitors, with a correction data management function, can pre-store multiple sets of correction data to match different batches of test sensors.

• Professional processing of TC reference junction

The aluminum alloy thermostatic block with the built-in high-precision temperature sensor can provide CJ compensation with an accuracy better than 0.2℃ for the thermocouple measurement channel. Combined with 0.01% electrical measurement accuracy and the application of low-potential scanning switches of the PR203/205, they can easily meet the demanding requirements of the AMS2750E specification for test instruments.

• Channel detection function

In this mode, before the acquisition, whether all channels are connected to sensors can be automatically detected by the aquisitor. During the acquisition, the channels that are not connected to sensors will be automatically closed according to the acquisition results.

• Dry-wet bulb method to measure humidity

There are many usage restrictions when  commonly used humidity transmitters are continuously operated in high humidity environments. PR203/205 series acquisitors 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.

• Channel expansion function

Channel expansion can be achieved by connecting

supporting modules: under the TC module, additional

40 thermocouple test channels can be provided; under

The RTD module, 8 resistance thermometer channels

And 3 humidity channels can be added; under the WET

module, 10 humidity channels can be added. In order to

add the modules, the module and the aquisitor can be connected together only by the connection of a dedicated connector.

• Built-in storage function

The PR203/205 series acquisitors can store acquisition data in a U disk during the independent operation. The stored data in the U disk can be browsed or processed with Excel, or imported into special software for data analysis and output as reports and certificates. In addition, PR2

solution: they have a built-in large-capacity FLASH memory, and support double backup of original data; the original data in FLASH can be viewed in real time and can be copied to a U disk by one clicking, which further enhances the data safety and reliability.

• Detachable lithium battery with large capacity

The PR203/205 series adopt the detachable large-capacity lithium battery for power supply and adopt a low-power design. Taking the PR205 series products as an example, in the case of battery-powered, they can work continuously for more than 20 hours, and can avoid measurement disturbances caused by the usage of AC power.

• Wireless communication function

R203/205 series acquisitors can be connected to peripherals such as computers through 2.4G wireless local area networks. A wireless local area network can support multiple acquisitors to carry out temperature uniformity testing at the same time, which effectively improves work efficiency and simplifies the wiring process.

• Powerful human interface

The human interaction composed of touch screen and mechanical keys can not only provide convenient operation, but also meet the reliability requirements in the actual operation. With a rich operation interface, what can be set include: channel settings, acquisition settings, system settings, curve drawing, data analysis, historical data viewing and data calibration.

• Supporting PANRAN smart metrology APP

The PR203AC temperature and humidity acquisitors are used in conjunction with the PANRAN smart metrology APP to realize many functions (such as the real-time remote monitoring, recording, data output, alarming) of the networked equipment; the historical data is stored in the cloud service, which is convenient for query and data processing; the software is with rich permission configuration module, so the user can independently manage the account of its unit; multiple users can be activated simultaneously online and different user authority levels can be configured.
