  • LC-110H - Precision Current Loop Calibrator With Hart Communications The Martel LC-110 and LC-110H are mA (loop) calibrators designed to take the loop calibrator class to the next level. The new LC-110 series feature a user friendly interface with dedicated buttons and a rotary encoder (Quick-Set Knob). This combination drastically reduces the time it takes to measure, simulate, or source both voltage and current and power up a loop. The rugged ABS plastic case is contoured to easily fit a technician's hand and the large back lit graphics LCD is best in class. The LC-110H differs from the standard LC-110 in that it incorporates HART communications and supports a select set of the HART universal and common practice commands. This unique feature allows the LC-110H to be used as both a loop calibrator and communication tool.
