High and low temperature environment temperature and humidity measurement in large space
PR750 series high-precision temperature and humidity recorder (hereinafter referred to as “recorder”) is suitable for temperature and humidity testing and calibration of large-space environment in the range of -30℃～60℃. It integrates temperature and humidity measurement, display, storage and wireless communication. The appearance is small and portable, its use is very flexible. It can be combined with PC, PR2002 Wireless Repeaters and PR190A data server to form the various testing systems that are suitable for temperature and humidity measurement in different environment.
I Features
Distributed temperature and humidity measurement
A 2.4G wireless LAN is established through the PR190A data server, and one wireless LAN can accommodate up to 254 temperature and humidity recorders. When using, just place or hang the recorder in the corresponding position, and the recorder will automatically collect and store temperature and humidity data at preset time intervals.
Signal blind spots can be eliminated
If the measurement space is large or there are many obstructions in the space to cause Degraded communication quality, the signal strength of WLAN can be improved by adding some repeaters (PR2002 Wireless Repeaters). which can effectively solve the problem of wireless signal coverage in large space or irregular space.
Software and hardware design to ensure the reliability of test data
In the case of abnormal or missing data sent and received by the wireless network, the system will automatically query and supplement the missing data. Even if the recorder is offline during the entire recording process, the data can be supplemented in the U disk mode later, which can be used for Users provide complete raw data.
Excellent full-scale temperature and humidity accuracy
In order to meet the diverse calibration needs of users, different types of recorders use temperature and humidity measuring elements with different principles, which have excellent measurement accuracy in their full range, providing reliable guarantee for temperature and humidity traceability and calibration.
Low power consumption design
PR750A can work continuously for more than 130 hours under the setting of one minute sampling period, while PR751 series products can work continuously for more than 200 hours. The working time can be further increased by configuring longer sampling period.
Built in storage and U disk mode
Built-in FLASH memory, can store more than 50 days of measurement data. And can charge or transfer data through Micro USB interface. After connecting to the PC, the recorder can be used as a U disk for data copying and editing, which is convenient for fast processing of test data when the local wireless network is abnormal.
Flexible and easy to operate
No other peripherals are needed to view the current temperature and humidity value, power, network number, address and other information, which is convenient for users to debug before networking. Furthermore, users can easily configure different environmental temperature and humidity calibration systems according to the actual needs.
Excellent software features
The recorder is equipped with professional temperature and humidity acquisition software. In addition to the regular display of various real-time data, curves and data storage and other basic functions, it also has visual layout configuration, real-time temperature and humidity cloud map display, data processing, and report output functions.
Remote monitoring can be realized with PANRAN intelligent metrology
All the original data in the whole test process will be sent to the cloud server through network in real time,The user can monitor the test data, test status and data quality in real time on the RANRAN smart metrology app, and can also view and output historical test data to establish a cloud data center, and provide users with long term data cloud storage, cloud computing and other services.

III Components
PR190A data server is a key component to realize the data interaction between recorders and cloud server, It can automatically set up a LAN without any peripherals and replace the general PC. It can also upload real-time temperature and humidity data to the cloud server through WLAN or wired network for remote data monitoring and data processing.
PR2002 wireless repeater is used to extend the communication distance of 2.4G wireless network based on zigbee communication protocol.With built-in 6400mAh large-capacity lithium battery, the repeater can work continuously for about 7 days. PR2002 wireless repeater will automatically connect the network with the same network number, the recorder in the network will automatically connect to the repeater according to the strength of the signal.
The effective communication distance of the PR2002 wireless repeater is much longer than the transmission distance of the low-power transmission module built in the recorder.Under open conditions, the ultimate communication distance between the two PR2002 wireless repeaters can reach 500m.
