Introduction - palintest Photometer 7500 Operation Manual

1. Introduction

The Palintest Photometer 7500 Bluetooth is a direct-reading,
waterproof photometer for determining key water quality
parameters for drinking water, wastewater and process water
samples. Designed for both portable and laboratory use, the
Photometer 7500 Bluetooth should always be used with
genuine Palintest reagents for optimal performance.
The fundamental operating technique applied to the
Photometer 7500 Bluetooth 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 Photometer 7500 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.

photometric and turbidimetric analysis technology please visit

The Photometer 7500 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. Upon completion of the test
