Colorimeter
: IP67 Waterproof
Portable
Colorimeter
measures Free Chlorine, Total
Chlorine, Cyanuric Acid and pH
Our C401 colorimeter measures Free Chlorine, Total
Chlorine,
Cyanuric Acid and pH. This latest laboratory-grade
microprocessor-based colorimeter offers quick, accurate and
repeatable results. The meter comes with large custom-made LCD and
user-friendly self-diagnostic warning messages.
These Colorimeters are supplied with reagents and sample vials in
rugged carrying cases for swift testing on the go. Be it for
swimming pools, spas, industrial wastewater, municipal treated water
monitoring, paper and pulp mills or water conditioning control, you
can select from the C401, C301, C201, C101 or C102 models. Excellent
repeatability, auto-ranging and easy to use. The meter ensures
excellent repeatability, has auto-ranging capabilities while using
only one-vial-one-sachet per test.
Main Features :
-
High Quality
Reagents
The custom-formulated reagents provide excellent accuracy,
repeatability and stability. They are conveniently packed
for ease of use.
-
USEPA-approved
DPD method*
Chlorine measurements are based on the USEPA-approved DPD
method*.
-
Advanced
Power Management
The meter is capable of measuring more than 3,000 tests
using a single set of 4 ‘AAA’ alkaline batteries. Auto
power-off activates after 10 minutes of non-use to conserve
battery life.
-
Fuss-free
Meter Operation
The meter is designed for easy operation. It allows one-time
blanking for all parameters and ranges when measuring the
same sample. The blanking value is stored in memory even if
batteries are replaced. Furthermore, no calibration is
needed for Chlorine and Cyanuric Acid. Most importantly, the
meter is maintenance-free.
-
Large
Easy-to-read Display
The large screen features 4-digit 14-segment customized
liquid crystal display (LCD) with mode indicators to guide
meter use.
-
IP67
waterproof and lightweight
The lightweight meter has a waterproof IP67-rated housing.
It even floats when accidentally dropped in water.
*Procedure is equivalent to
USEPA method 330.5 for wastewater and Standard Method 4500-Cl G for
drinking water.
