Martel LC-110H High Accuracy HART Loop Calibrator

Martel LC-110H High Accuracy HART Loop Calibrator

The Martel LC-110H is a flagship loop calibrator engineered to deliver elite operational performance for characterizing 4-20 mA control loops and HART-enabled instrumentation. By addressing the requirement for surgical accuracy in process audits, this instrument provides a best-in-class precision of 0.01% of reading, effectively minimizing measurement uncertainty during the configuration and troubleshooting of smart transmitters. The metrological architecture of the LC-110H ensures absolute traceability, featuring a built-in 250Ω resistor for seamless HART communications and the ability to capture twenty transmitter configurations for high-fidelity data management via BetaLOG software.

Built for industrial longevity, the LC-110H is a high-trust solution for managing stimulus, offering a unique “Valve Test” mode to simulate defined mA values with percentage-based keys for surgical oversight of final control elements. Its technical sophistication allows technicians to monitor PV units, PV mA, and PV percentage while simultaneously performing DAC trim adjustments on the zero and gain of the device under test. As a professional-grade metrology tool, this calibrator provides the repeatable performance and rigorous verification required for maintaining the integrity of modern smart-process infrastructure in chemical, energy, and water treatment plants.
