1.0 Introduction

The Palintest Pooltest 25 is a direct-reading,
waterproof photometer for determining key water
quality parameters for swimming pools,
hydrotherapy pools, hot tubs and spas. Designed
for both portable and static use, the Pooltest 25
should always be used with genuine Palintest
reagents for optimal performance.
The fundamental operating technique applied to
the Pooltest 25 is based on the principles of optical
absorbance and scattering of visible light.
Optical absorbance techniques are based on the
use of Palintest (spectro)photometric reagents,
creating visible colours with specific analytes
upon reaction. The intensity of colour produced is
measured with the Pooltest 25 and the data
compared to the stored calibration data to deliver
the final result.
Optical scattering techniques produce small
particles to scatter the source beam, the amount
of scatter providing a result for the concentration
of parameter under test.
The Pooltest 25 is provided with programmed
methods for a comprehensive range of water
quality parameters. Upon choosing a test the
instrument automatically selects the required
parameters for accurate analysis including
wavelength and reaction time. On completion of
some tests optional follow-on tests are available
plus results can be converted to alternative units
of expression e.g. mg/l to ppm, N or NH
The Pooltest 25 offers a choice of connectivity
to download all or selected results via 4.0
wireless connectivity or USB connection.
The Pooltest 25 offers a choice of either mains
power via the USB port or using three 1.5V 'AA'
batteries (supplied).
The Pooltest 25 is delivered with a two year
warranty and a full range of service, calibration
and technical support. Additional resources are
available at www.palintest.com relating to both
products and applications.
