Product Introduction
The CL-420B is a handheld, programmable calibrator for measurement and signal output. It's great for measuring tiny currents and voltage signals, and it can power sensors while checking their returned current signals. Mainly used in sensor testing and monitoring gear, like for humidity, water level, wind speed, pressure, and other sensors and monitors. It's got this cool feature where it controls the minimum current in a live loop, and it can measure in a sensor's live loop too. Definitely a must-have tool for folks fixing up sensor equipment.
