"Vaiseshika" Digital Thermocouple Test Set and Calibrator Type : 7709 EP
Description
Digital Thermocouple Test Set and Calibrator type 7709 EP is an EPROM (Erasable Programmable Read-only-Memory) based design. The instrument can accept J, K, S, R and T type of thermocouples in the same equipment. The instrument is ideal to measure temperatures with J, K, S, R and T type of thermocouples as well as for the calibration of temperature indicators employing J, K, S, R and T type of thermocouples. excellent liberalization of the order of 1șC is attained over the complete range of thermocouple viz. J, K, S, R, and T.
4 Digits Digital Thermocouple Test Set and Calibrator is a versatile equipment in the area of thermal engineering. The instrument is ideal to calibrate temperature gauges, potentiometric recorders, platinum resistance thermometers, temperature controllers and recorders. The instrument can also be used as a thermocouple simulator. A calibrated stable potential source, continuous variable from 0 to ± 100 mV, is provided with the test set. The potential variation can be done with a resolution of 1șC. Similarly temperature sensed by a thermocouple in a furnace can be monitored with Digital Read Out Display in this instrument.
A standard Wheatstone bridge is also provided with the test set. The resistance ranging from 0.1 ohm to 1K ohm can be measured and simulated with an accuracy of ± 0.1%.
