Presys T-25NL T-45NL T-700PL Calibration Baths – for Large Calibration Volume

The T-25NL, T-45NL and T-700PL models control temperature over the bath or insert with high accuracy in order to calibrate thermocouples, thermoresistances, glass thermometers, thermoswitches,etc. Besides this, the T-25NL and T-45NL come with a stirred liquid bath function and black body target function and the T-700PL comes with a black body target function. 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™
