PR233 Process Calibrator

Products Detail


PR233 series process calibrator is a thermal special testing instrument. There are two kinds of accuracy grade products available. It not only has the basic function of measurement and simulation for voltage, resistance, current, thermocouple, thermal resistance, frequency, switch signal, etc, but also has the ability to measure the value of ρ and pressure (limited to PR233A). The equipment adopts industrial grade touch-screen operation. In addition, you can also select the wireless communication module, so which is easy to operate. This product design is exquisite and easy to carry, so it’s suitable for industrial field. It is the preferred equipment for thermal measurement industry.

Performance characteristics:

● The simulating resistance and thermal resistance are very adaptable. It can provide a stable signal for the two instruments, such as the circle chart recorder, the mechanical balance recorder and so on.

● Its measurement and output functions are isolated from each other, which makes two functions can be used simultaneously.

● Human-computer interaction consists of industrial resistance touch screen and mechanical key. Users can not only set up with the touch screen, but also do common operation with mechanical buttons.

● The function of resistance measurement can be classified as two lines, three lines and four lines.

● High-precision reference junction temperature compensation is put inside, and the fast interface of the thermocouple is installed.

● It is provided with a recording function, which makes the scene of paperless recording can be achieved.

● With isolated 24V power supply put inside, the verification of temperature transmitter is more convenient.
