PR205 Temperature and Humidity Acquisition system

Products Detail


 

Product overview:

  PR205 series temperature and humidity Acquisition system 0.01 level accuracy. It can connect 64 thermocouple or 20 thermal resistance and 6 humidity sensor. The measured value and the temperature of each channel can be displayed at the same time, and it’s a special instrument for the temperature and humidity field inspection. After connecting to host computer, it can take automatic test and analysis on temperature controlling deviations, temperature field, humidity field, uniformity and volatility of heat treatment furnace and equipment for environment temperature (or humidity) test. The standards and methods for the test cover the national standard, the military standard and various existing norms


Performance characteristics:

1. It is equipped with large capacity lithium batteries, so as to avoid the interference caused by AC power supply.
2. High inspection speed. The speed of thermocouple inspection is 0.1s per channel; the speed of the thermal resistance is 0.5s per channel.
3. The unique structure of the terminal plug is installed in the PR205A type equipment; facilitate the installation and removal of the sensor.
4. It has internal and external reference junction compensation mode. The error of reference junction compensation temperature and interchannel are all less than 0.2℃.
5.  It supports U disk. Inspection data can be saved to the U disk, and the storage file can be edited by use of excel.
6.  It can realize the complex human-computer interaction function by the use of resistive touch screen and mechanical key combination operation mode.
7. It adopts the design of low power consumption. Under normal operation, it can work more than 20 hours continuously with battery power supply.
 8.  It has a wealth of features, in addition to the real-time display of all the channel inspection data which including temperature value and power value, but also has a curve drawing, short circuit cleared and other functions.
 9.  Wet and dry bulb to measure humidity.


Application

1. temperature uniformity test for heat treatment furnace.

2. temperature uniformity test for temperature and humidity field.
