Description

LR-Cal LTC 100 Description

The temperature calibrator LR-Cal LTC 100 simultaneously measures and sources ten types of thermocouples and seven resistance temperaure detectors (RTD), whilst automatically capturing the calibration results. It measures milliamps whilst sourcing or simulating millivolts, TCs, RTDs or ohms to calibrate transmitters.

The LR-Cal LTC 100 logging facility stores data on the SD card supplied, which is easily downloaded to a PC via the onboard USB port and usable in most of the common spreadsheet formats.

The trend feature is ideal for graphing temperature profiles and PID controller optimization with a programmable timebase. In addition, the LR-Cal LTC 100 has the functionality necessary to install and maintain all powered and non-powered transducers using the built-in 24V loop power supply.

The multifunctional Temperature Calibrator LR-Cal LTC 100 is the economical choice for people wanting to do industrial field or workshop calibration.

Included in standard delivery is a rubber boot, a SD memory card, a Thermocouple Extender (with cold junction compensation) and a plastic case with foam.

The operation of the Temperature Calibrator LR-Cal LTC 100 is very simple and easy. Example: the Help-Menu shows on the display Wiring Schematics for almost all kind of testing and calibration tasks.
