Colorimeters Or Photometers......
The Colorimeters or Photometers are at the higher
(Some would say Highest) accuracy level of water testing equipment
available in today's market. There are two available for testing
Chlorine, both of which will test for Free Chlorine, Which we aren't
overly bothered about and the all important Total Chlorine, this is
the number that matters to the Koi world....
The two units are very similar with only the slight
difference of been able to calibrate one of the units to give
maximum accuracy for testing.
Single Parameter Colorimeter....Chlorine.....
This meter measures Free & Total Chlorine, Free
Chlorine measures from 0.00 to 2.50mg/L and the Total Chlorine
measures from 0.00 to 3.50 mg/L.
Please note that this item does not come complete
with any reagents and you do need to purchase these
separately.....Please see the full instructions below to see what
extras you will need....

An important note to remember when
deciding on a Chlorine tester is that whilst the colour changing
kits are the lower end of budget we don't all see colours in the
same way.....But the final choice would be down to a How much you
want to spend VS How accurate you want the result......
Single Parameter Colorimeter....Chlorine.....Complete With
Calibration Check Feature......
Working in the same way as the above product this
Colorimeter comes complete with the calibration check feature, This
allows for instrument validation at any time using the calibration
Cuvets.
The HI-95711C kit includes the meter in a rugged
carrying case, Cal Check standard and accessories. Reagents are NOT
included.
