Our loop calibrators deliver the accuracy and functionality you need for maintaining and calibrating 4 to 20mA loops. They allow you to calibrate milliamp instruments by reading, sourcing and simulating. Transcat offers premier products from Fluke, Druck, Altek and PIE within our calibrator category. Recorders, indicators, and additional instruments with 4 to 20 mA loop input can be calibrated with a handheld device from our inventory. You’ll be able to quickly perform checks on wiring or receivers. For testing in explosion-susceptible environments, we offer intrinsically safe loop calibrators. You can also find compact devices with specialized features such as automatic leakage indication, lab-level accuracy, or HART compatibility.
