PR203 series temperature and humidity acquisitors, with accuracy of 0.01%, and can connect up to 72 thermocouples, 24 thermal resistances, and 15 humidity transmitters. With rich human-computer interaction functions, it can display the electric data and temperature data of each channel at the same time. It is a dedicated portable instrument for temperature and humidity field testing. This series of products can be connected to a PC or a cloud server by wired or wireless means, enabling automatic testing and analysis of temperature control deviation, temperature field, humidity field, uniformity, and volatility of heat treatment furnaces, temperature (humidity) environmental experimental equipment, etc. At the same time, this series of products adopts a closed design, which can work for a long time in the harsh environment with many dusts such as workshops.
I. Features
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 correction value management function can automatically correct the data of all temperature and humidity channels according to the existing user configuration. Multiple sets of correction value data can be pre-stored 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.
Channel Detection Function
Before the acquisition, it will automatically detect whether all channels are connected to sensors. During the acquisition, the channels that are not connected to sensors will be automatically closed according to the detection results.
Channel Expansion Function
Channel expansion is realized by connecting supporting modules, and the connection between the module and the host only needs to be connected through the special connector to complete the operation of adding modules.
Optional Wet and Dry Ball Method to Measure Humidity
When measuring a high humidity environment for a long time, the wet and dry bulb method can be used for humidity measurement.
Built-in Storage Function,Support Double Backup of Original Data
The built-in large-capacity FLASH memory supports 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-key export, which further enhances the safety and reliability of the data
Detachable High-capacity Lithium Battery
A detachable large-capacity lithium battery is used for power supply and a low-power consumption design is adopted. It can work continuously for more than 14 hours, and can avoid the measurement disturbance caused by the use of AC power.
Wireless Communication Function
PR203 can be connected to other peripherals through 2.4G wireless local area network, support multiple acquisitors to carry out temperature field testing at the same time, which effectively improve work efficiency and simplify the wiring process.
Powerful Human-computer Interaction Functions
The human-computer interaction interface composed of color touch screen and mechanical buttons can provide a rich operation interface, including: channel setting, acquisition setting, system setting, curve drawing, data analysis, historical data viewing and data calibration, etc.
Support Panran Smart Metrology APP
Temperature and humidity acquisitors are used in conjunction with the PANRAN smart metrology APP to realize remote real-time monitoring, recording, data output, alarm and other functions of networked devices; historical data is stored in the cloud, which is convenient for query and data processing
