Chlorine Testing Ranges; Water Balance Options - palintest Pooltest 25 Manual

Chlorine Testing Ranges

The Pooltest 25 features a new range of chlorine testing, allowing the
measurement of free and total chlorine up to 10 mg/l (ppm) without the
need for sample dilution. The instrument may be set up to use DPD No 1
and DPD No 3 tablets for the standard 0 - 5 mg/l chlorine range, or
alternatively may be set to use DPD-XF and DPD-XT tablets for the new
Palintest Chlorine/10 extended range, which offers a 0 – 10 mg/l chlorine
range. A simple menu selection in the system menu allows the user to
choose the range required.

Water Balance Options

Water Balance data allows pool operators to assess the corrosive and scale
potential of the pool water.
The Pooltest 25 features two different methods for determining Water
Balance. For simplified water balance testing (ie not requiring measurement
of TDS or temperature) use the Palintest Balanced Water Index. To
incorporate TDS and temperature measurements use the Langelier Index.
A simple menu selection in the system menu allows the user to choose the
method they prefer.
The most common (and more complex) method for determining water
balance is the Langelier Index which requires the measurement of TDS and
temperature. This data is manually entered into the photometer using the
keypad.
