CDH-23
$
175
⻬ Large 3" Scale for Easy Readability
⻬ Automatic Temperature Compensation (CDH 23 & 27)
⻬ Integral Sampling Cup
⻬ Easy One-Hand Operation
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/in3and 10K to 400 ohm/in3.
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.
