1 - Introduction

T-650PH dry block calibrator controls temperature of an insert in order to calibrate
thermocouples, thermoresistances, glass thermometers, thermoswitches etc. Besides
providing high accuracy temperature values, it also allows the measurement of signals
generated by thermo-elements 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 mA.

T-650PH calibrator model generates temperatures from room temperature to
650ºC (1202ºF).

Present input for thermocouples, RTDs, thermoswitches. Besides generating
temperature, they measure the signal from the sensor being calibrated.

Allows the control of the dry block temperature by using an external probe
(optional). The temperature calculation uses Callendar-Van Dusen coefficients.

Make no use of external standard thermometer.

Carries 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
Calibration Software.

Portable, compact, provide interchangeable inserts and carrying case.
It presents a wide variety of programming resources, allowing the performance of
automatic calibrations of thermocouples, RTDs, 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
ISOPLAN Calibration Software for PC/Windows
communication to connect the computer to the dry block. With ISOPLAN 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.
