Dry Blocks for Temperature Calibration T-25N T-35N T-50N

The T-25N, T-35N and T-50N models control temperature over an insert in order to calibrate thermocouples, thermoresistances, glass thermometers, thermoswitches,etc. Besides providing high accuracy temperature values, they also allow the measurement of signals generated by the thermocouples, thermoresistances and thermoswitches, which are being calibrated. This is possible due to an embedded calibrator specific for these types of signal, including 4-20 mA. They incorporate the function of dry block, standard thermometer and calibrator for RTD and TC sensors, besides mA reading. They present a wide range of programming resources, allowing them to perform automatic calibration of the sensors. In this case, the sensor is placed in the insert and its electrical terminals are connected to the embedded calibrator, the operator defines the calibration points and the number of repetitions, then the process is started so that all the sequence is automatically accomplished. Another way of performing automatic documented calibrations is by means of ISOPLAN-5 calibration software for PC/Windows™ which uses the RS-232 serial port to connect PC to the dry block. With ISOPLAN-5 it is possible to register sensors and instruments of the factory, generate work orders, create and print calibration certificates and reports, that is, it brings all the advantages of computer data management to the calibration environment.
