1 - Introduction

T-350P / T-650P dry block calibrators control temperature of 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 thermo-elements like 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. Thus, they incorporate the
functions of dry block, standard thermometer and calibrator for RTD, TC and also mA.

T-350P / T-650P calibrators model generate temperatures from room temperature
to 350ºC (662ºF) and 650ºC (1202ºF), respectively.

Present input for thermocouples, thermoresistances, thermoswitches. Besides
generating temperature, they measure the signal from the sensor being
calibrated.

Make no use of external standard thermometer.

Carry out completely automatic calibrations with or without the use of a computer.
 Accuracy to 0.1ºC  0.1% of reading, stability of 0.05ºC and resolution of 0.01ºC.

Documenting capabilities: communication with computer and CS-504 Calibration
Software.

Portable, compact, provide interchangeable inserts and carrying case.
They present a wide variety of programming resources, allowing the performance
of automatic calibrations of thermocouples, thermoresistances, thermoswitches. In this
case, the sensor is placed in the insert and their electrical terminals are connected to the
embedded calibrator. The operator defines the calibration points and the number of
repetitions, then the process is started and all the sequence is automatically
accomplished.
Another way of performing automatic documented calibrations is by means of
CS-504 Calibration Software for PC/Windows
communication to connect the computer to the dry block. With CS-504 it is possible to
register sensors and instruments of a factory, generate work orders, create and print
calibrations certificates and reports, that is, it brings all advantages of computer data
management to the calibration environment.
