Yokogawa CL420 clamp-on process meter

Yokogawa’s CL420 clamp-on process meter is designed to make checks on DC mA lines without breaking the circuit. This compact instrument is an effective troubleshooting tool for 4-20 mA current loops on equipment such as flowmeters, field instrument transmitters, signal conditioners, distributors, valve positioners and meters, saving users valuable time on site.

The CL420’s clamp has a relatively large hole that allows proper clamping around conductors up to 6 mm in diameter and ensures stable readings with an accuracy of 0.2% up to 20 mA. The backlit dual display provides both current value and percentage of range information along with battery condition. Convenient in low light situations, the CL420 incorporates a LED torchlight and illuminated panel keys. The unit has two input ranges, 0-20 mA and 0-100 mA, plus an analog DC mV output for use with a DMM, recorder or data logger. Other functionality includes an auto-power-off feature and data-hold.

The CL420 comes with a soft carrying case plus batteries and optionally available are output cables with either banana plug or screw terminals.
