LUTRON PCD-431 CONDUCTIVITY METER HANDY
Overview
The Lutron PCD431 is an economical yet rugged pocket tester for conductivity and TDS. It is autoranging with selectable TDS or conductivity, and so replaces up to 4 different models from our main competitor. Accuracy is +/-3% of fullscale. Because of the adjustable ATC factor, good accuracy is possible over a wide temperature range. Auto power off and rugged IP67 and sensor cover makes this a very handy mobile tool.
