PANRAN Temperature Calibrators simulate process sensors for testing temperature instrumentation.
Specifically designed for the field, these lightweight compact tools are EMI tolerant, dust and splash resistant and offer an easy to use single push button interface. When paired with a temperature sensor they can take high accuracy temperature measurements to verify process temperatures and ensure the highest product quality and safety. There are a variety of different temperature calibrators designed for your unique calibration and testing requirements.
PANRAN offers a wide range of temperature calibration equipment. Everything from simple Stik Thermometers to temperature simulation/measurement calibrators to dry-blocks, micro-baths and metrology wells. Whether you’re looking to calibrate a temperature transmitter in the field, test an RTD sensor, simulate a thermocouple, or calibrate a temperature transmitter at the bench, PANRAN has a temperature calibrator for you.
Powerful, easy-to-use, high-accuracy temperature calibrator
Test and calibrate temperature sensors and transmitters
Measures 4 to 20 mA loops and can provide loop power
Measures RTDs, thermocouples, ohms, and volts
Source/simulates thermocouples, RTDs, volts, and ohms
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).
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.
thermal calculator
It is used to achieve various conversions between electric and temperature. The conversion support a variety of TCs, RTDs and thermistors.
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.
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.
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.
