Residual Chlorine Meter
●Single-packet powder reagent combining buffer and color-developing agents in one formula. Simplifies measurement procedures and enables rapid reaction.
● Usage: Pour 10mL (up to 20mL) of test water into a clear container (colorimetric cell), then add one packet of reagent.
Free residual chlorine—an indicator of sterilization strength—will turn pink immediately if present.
Color change indicates chlorine presence.
※For measuring concentration by color comparison with the color plate using the "Empathester" in ③–④, we recommend this method.

Kazusa DPD Method Residual Chlorine Meter
Empathester
Measure 2 parameters with one unit!
(S・SW only) ※SA・SWA do not include pH meter.
Fill the color comparison cell with sample water. For residual chlorine measurement, add DPD Reagent S; for pH measurement, add BTB indicator.
Color develops, and readings are taken by comparing the color with each color comparison dial—an extremely accurate meter.

< Applications >
Management of drinking water in simple water systems, wells, building water tanks, and pools
Can be used for water testing. According to the Water Supply Law,
"chlorine disinfection shall be applied so that water at the water supply outlet
maintains free residual chlorine of 0.1 mg/ℓ or more (or 0.4 mg/ℓ for combined residual chlorine)".
For pool water, hygiene standards are specified by Ministry of Health notification, stating that
"free residual chlorine concentration should ideally be 0.4 mg/ℓ or more and less than 1.0 mg/ℓ".
Support the nozzle with your finger
while turning the knob
to cut it off.
⟨Operating Procedure⟩
Press the pump section with your finger
to expel air from the container.
Insert the nozzle into the test solution,
then slowly release the finger
grip on the pump to
draw the test solution into
the pump section.
Hold the nozzle section and shake
the color reagent and test solution
together, then compare the color to the
standard color chart (colorimetric
comparison) and determine the concentration.

Simple pack enables easy water quality testing.
● Lightweight, compact analysis set
Extremely compact container fits in the palm of your hand (approximately 55mm from nozzle to pump), so it's space-saving and lightweight.
● Operation is simple — just draw in test water and shake
Draw test water into the reagent container, shake, and the reaction completes in 10 seconds to
several minutes.
● Only the Simple Pack and included color chart needed — nothing else
(COD, NH₄, PO₄ excluded)
Quantify by simply comparing the colored test water against the included color chart
with minimal staff.
● No experience or specialized knowledge required
Just draw in test water and compare colors — no specialized experience
or knowledge necessary.

< Applications >
Residual Chlorine 100 measures residual chlorine at slightly high concentrations of 5–100 mg/ℓ.
pH range 2–12 covers acidic to alkaline water, enabling testing across a wide range of applications.
Suitable for strong acidic electrolyzed water, weakly acidic electrolyzed water, alkaline reduced water, and residual chlorine measurement in pool footbath tanks.
Also measures residual chlorine in these applications.
Also compatible with sodium hypochlorite solution used for sterilizing and washing vegetables and produce.
