General Information

2.1
The waterproof C401/301/202/102/101Colorimeter allows you to measure
up to four parameters - namely the pH, Cyanuric acid, Free Chlorine and
Total Chlorine of a sample and reports the results in appropriate units
(ppm or pH). Each specific measurement has its own range as listed in the
specifications.
The meter will go through a power sequence as shown below.
Meter's Model Number
An accurate colorimeter measurement depends on good measurement
techniques. Factors such as clean sample vials, positioning of vial in the
sample well, covering the vial with the light shield cap, meter calibration,
handling of meter, and others, have to be taken into consideration.
NOTE: Do not pour liquid directly into the sample well of the instrument.
Always use a vial. The instrument will only accurately measure the sample
when vials sealed with the black caps are used. The black cap serves as
both seal and a light shield.
NOTE: Do not attempt to clean the sample well. The optics may be
damaged.
NOTE: This instrument is designed to measure solutions contained in the
custom made glass vials and therefore the use of other type of sample vials
or sample cells may result in inaccurate measurements.
