The CDH-23, CDH-27 and CDH-29 are simple-to-operate, battery powered portable meters which indicate either conductivity or resistivity on a stable, easy-to-read analog display, designed and calibrated specifically for monitoring water quality. These handheld meters feature integral sample cup sensors, water and chemically resistant ABS cases, and rubber booted switches. Conductivity Meters The CDH-23 and CDH-27 display conductivity in both Micromhos and Parts Per Million and feature automatic temperature compensation. The economical CDH-23 ($175) is ideal for measuring the performance of Reverse osmosis and other drinking water filtration systems with a single range of 0-1200 PPM. The CDH-27 ($275) displays conductivity across three switchable ranges of 0-50, 0-500, and 0-5000, providing improved accuracy and readability. Resistivity Meter The CDH-29 ($295) is designed for water quality measurements in units of resistivity across two switchable ranges of 500K to 20K ohm/in cubed and 10K to 400 ohm/in cubed . Note: The CDH-29 is a convenient, portable instrument; however, stable measurements of extreme resistivity of pure water can only be accomplished in a hermetically sealed process system.
