Photometer 7500 BT
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.

both photometric and turbidimetric analysis

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 optional follow-on tests are available
and results can be converted to alternative units
of expression e.g. mg/l to ppm, N or NH

.
The Photometer 7500 Bluetooth offers a choice of
connectivity to download all or selected results and/or
upload up to 30 User Defined Tests. Choose from
Bluetooth 4.0 wireless connectivity or USB connection.
Bluetooth 4.0 (also known as Bluetooth SMART or Low
Energy) connection allows seamless data exchange
using the Palintest Aqua Pal app, available for iOS
and Android devices. See Section 3.11 for more details.
USB connection via the port located at the rear
of the instrument provides a choice of either
‘Hard Disk’ mode or serial communication mode.
See Section 3.4 for more details.
The Photometer 7500 Bluetooth offers a choice
of either mains power via the USB port or using
three 1.5V ‘AA’ batteries (supplied).
The Photometer 7500 Bluetooth is supported
with a two year warranty and a full range of
service, calibration and technical support. Support
resources are available at
