Colorimeters C401, C301, C201, C105, C104, C103, C102 and C101


[ C104, C102, C101 had been discontinued ]

Eutech’s latest range of laboratory grade microprocessor-based portable waterproof colorimeters measure Chlorine (Free and Total), Cyanuric Acid, pH, Chlorine Dioxide, Bromine and Ozone with quick, accurate and repeatable results. The meters are easy to use because of their simple, intuitive and direct user interface. Guiding messages and self-diagnostics are displayed on a large custom-made liquid crystal display (LCD). Each meter comes with reagents and sample vials in a rugged carrying case for swift testing-on-the-go. This family of colorimeters is designed for reliable and convenient water analysis in swimming pools, spas, public utilities, industrial wastewater plants, municipal water, treated water, water conditioning systems and paper and pulp mills. Select from our wide range of models, designed to meet your application needs.

Product Features

:: 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.
   
:: 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.
