HAND-HELD TEMPERATURE & PRESSURE CALIBRATION

January 29, 2015  1226  1226   

Instrotech’s locally designed and manufactured Calog range of portable process control calibrators incorporate the most modern component technology, comprehensive feature capabilities and tough package design, making the units ideal for use in servicing, repairs in workshops and in tough plant environments.

Calog-TEMP high precision, multifunctional temperature calibrator - which measures milliamp, millivolt, thermocouple, ohm and resistance temperature detector (RTD) in a single device. The temperature ranges are isolated from the mA and can be displayed simultaneously. Injecting thermocouple millivolts (or RTD ohms) into a transmitter while measuring the output (mA) simplifies field or workshop calibration.

All commonly used thermocouples types K,J,T,B,R,S,E,N,U,L and RTD types Pt50, Pt100, Pt200, Pt500, Pt1000, Ni100 and Ni120 are included in the easy-to-use menu. The thermocouple ranges have automatic internal cold junction or manual or external temperature compensation. The ohms and RTD measurement is selectable for 2, 3, or 4-wire connection and sourcing of ohms and RTDs is in 2-wire form. The milliamp measurement can be passive or active with a 24 V power supply in the measurement line for 2-wire transmitters.

A plug-in extender is supplied with spring terminals for bare wire connection directly to thermocouple wires or compensating cables. The cold junction correction is built into this unit.

The back-lit LCD display can be selected for measurement in a clear, precise numeric display or as a graph for use when logging temperature or milliamps over longer periods. This is ideal for when monitoring ovens or optimising PID control.
