Product video

The PR231 series products have excellent performance indicators, numerous practical functions and powerful human-interface . The series includes two levels of accuracy, 0.01% and 0.02%. The measure and source are completely isolated, in addition to the general functions of a two-channel calibrator, it also has the measurement function of ρ value and standard temperature. The enhanced type also features a temperature difference test and a precision temperature control function. It is compact in design, portable, and suitable for on-site and laboratory applications, making it the first choice for temperature calibration.

Products Features

1.Temperature difference measurement with accuracy of 0.003 ° CPR231A calibrator measures the temperature difference between two points in space without other instruments. When the function is used, the four terminals of the source function be used as measurement terminals and the process of the temperature difference data acqusition can be completed within 0.4 Seconds, which effectively improves the accuracy of the measurement. The stability can also be calculated in real time during the test

2.Standard temperature measurement

Different from ordinary TC and RTD measurement, the standard temperature measurement may use the certificate value for temperature traceability. The input signals include:STC – > S type, R type, B type, T type.SPRT-> Rtp = 25Ω or Rtp=100Ω.

3.Reference Junction Compensation

The reference junction compensation methods of the PR231 series calibrator are very flexible and three methods are available, namely internal, external, and customized. The external reference junction adopts Grade A Pt100, and can input the certificate value for the reference junction data correction. When PR231 series calibrator is combined with PR1501 temperature equalization compensation module, a reference junction compensation error of less than 0.07°C can be obtained.

4.Precision temperature control function

Using the precision temperature control function, temperature closed-loop control of the constant temperature equipment can be realized instead of the high-precision PID controller. In the case that the constant temperature equipment and grid voltage are satisfactory to the conditions, the temperature fluctuation of the equipment can be better than 0.02°C /10min

(thermostatic bath).

5.ρvalue measurement

The PR231 series calibrator can measure the duty factor of the periodic square signal and can be used to verify and calibrate the PID parameters of various digital temperature indicating regulators for time proportional output, and meet the requirements of JJG 617-1996 Verification Regulation of Digital Temperature Indicators and Controllers.

6.Thermal calculator

It is used to achieve various conversions between electric and temperature. The conversion support a variety of TCs, RTDs and thermistors.

7.Value Settings

The PR231 series calibrator has the most flexible and convenient output value setting method. It is possible to directly set the output value through the numeric keypad, or to increase the increment setting by pressing the direction key. In addition, the device has an editable phase step or slope value setting method.

8.Sinusoidal signal output function

The verification/calibration of some process loggers, especially mechanical recorders, usually involves the operation test. In this case, the user can use the device’s sinusoidal signal output function to provide signals for the verified instrument.

The verification/calibration of some process recorders (especially mechanical recorders) usually involves the operation of the test. At this time, the device’s sinusoidal signal output function can be used to signal the meter.

9.Data logging function

The logging function saves measurement and output data. PR231 series calibrator has powerful record management functions. Up to 32 device numbers can be created. Each device number has 16 logging pages. Each logging page contains four kinds of basic information, namely time, measured value, output value and custom value. Basic information. Users can perform device processing, record deletion, etc. according to their needs.
