DP-04 and DP-04D 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.
integral sample cup sensors, water and chemically resistant
ABS cases, and rubber booted switches. The instrument handle
for protection make the instruments ideal for users requiring
portability without sacrificing reliability.
The DP-04 and DP-03 display conductivity in both Micromhos and Parts
Per Million and feature automatic temperature compensation. The economical
DP-04 is ideal for measuring the performance of Reverse Osmosis and
other drinking water filtration systems with a single range of 0-1200 PPM.
The DP-03 displays conductivity across three switchable ranges of
0-50, 0-500, and 0-5000 providing improved accuracy and readability.
The DP-04D is designed for water quality measurements in the Ultra
Pure range and displays Resistivity across two switchable ranges of ∞ to 20,000 ohm/in cubed and ∞ to 400 ohm/in cubed.
Note: The DP-04D is a convenient portable instrument, however
stable measurements of extreme resistivity of Ultra Pure Water can
only be accomplished in a hermetically sealed process system.
