quaprobe® P-6000 & P-7000Mk2 Instruction Manual 10401-01668 Rev B
1. Introduction
This manual covers the setup, operation, calibration and maintenance of the Aquaprobe®
AP-6000 & AP-7000Mk , Aquameter® V6. 0+ Meter, AquaLink V5.00+ PC software and
associated Aquaprobe® accessories. If your Aquameter® is running earlier firmware, the
functionality may differ from that shown in this manual. In this case, contact Aquaread for
an earlier version of this manual or return your equipment for firmware upgrade.
2. What’s in the Box?
The Aquameter® is supplied with the following:
•The Aquameter® unit.
•Quick release lanyard.
•Set of 5 AA Alkaline batteries.
•USB Cable for downloading logged data to a PC.
•Cross-head screwdriver for fitting the batteries and Probe maintenance.
•Getting started card for quick reference.
The Aquaprobe® is supplied with the following:
•Protective Sleeve End Cap.
•600mL of RapidCal Solution.
•Two part calibration / rinse cup.
•One mounting nut (pre-fitted).
•Mounting Bracket
To complete your system, you will also need an AP-5000/7000 Extension Cable, which
should be purchased separately.
2.1. The Aquameter® and the nvironment
The Aquameter® is designed to be used outdoors and is rated to IP67, that is to say it is
waterproof but it is not designed for submersion. In order to prevent accidental dunking or
loss, a lanyard is supplied. Please note that the socket on the Aquameter® is only
waterproof when the associated plug is fitted. Without the plug fitted, water can
enter the socket. Damage caused by water ingress through the socket is not covered
by your warranty.
You may notice a small hole on the rear of the unit near the top. This is a waterproof vent
for the internal barometric sensor. Do not poke anything in this hole! Doing so will cause
major damage to the vent’s waterproof membrane and invalidate your warranty.
2.2. The Aquaprobe® and the nvironment
The Aquaprobes are designed to be fully submerged in water and are rated to IP68, that is
to say, they are rated for continual immersion to a depth of 30 meters, and short term
immersion (less than 1 hours) to 100 meters.
The Aquaprobes are manufactured predominantly from marine grade aluminium. When
installing an Aquaprobe®, it is important to recognise and avoid the possibility of creating a
situation where galvanic corrosion can occur. See section .5.1 Important Notes Regarding
Galvanic Corrosion for more details.

2.3. About the Probe Sleeve and Sleeve nd Cap
The Aquaprobes are constructed with an aluminium sleeve surrounding the delicate
sensing electrodes. The Sleeve can be easily removed by unscrewing to allow cleaning of
the individual electrodes, however, The Probe sleeve, end cap and wiper form an
integral, working part of the Probe’s optical and C measurement system, and MUST
be fitted during calibration and measurement for correct operation.
All Aquaread® Optical Electrodes are incredibly sensitive. For example, the Turbidity
electrode is capable of measuring between 0 and 3000NTU with an internal resolution of
greater than 0.1NTU. This means that the electrode is able to detect changes in turbidity
that are less than 0.003% of the full range! The other optical electrodes have a similar level
of sensitivity.
It follows, therefore, that in order to
provide stable, repeatable readings,
the environment in which the
measurements are made must be
completely stable and repeatable.
For this reason, the Aquaprobes
are constructed with a matt black
aluminium sleeve and end cap that
enclose the sensing electrodes and
provide a closed, constant
condition, non reflective
measurement chamber.
The image to the right represents a
section through the AP-6000
showing the mechanics of the
measurement chamber and
illustrates how the wiper, sleeve
and end cap all have an affect on
the physical characteristics of the
chamber. The AP-7000 is similar.
In order to obtain consistent results, the measurement chamber created within the
Aquaprobe® must remain physically constant during both calibration and
measurement. It is therefore essential that both the sleeve and sleeve end cap are
fitted during calibration and operation of all types of optical electrodes.
If an optical electrode is calibrated under one set of conditions then used to measure under
another set of conditions, the readings will naturally be erroneous, especially at low
concentrations.
A perfect example of this is calibrating with the end cap removed then measuring with the
end cap fitted (or vice-versa). By changing the physical characteristics of the measurement
chamber, you also change the calibration and response of the electrode.

2.4. Top Tips for successful measurements using optical electrodes
•Always keep the measurement chamber and electrode lenses clean.
•Always fit the wiper, sleeve and end cap during both calibration and measurement.
•Always allow the readings to settle completely during both calibration and
measurement.
•Always try to eliminate air bubbles by activate the self-cleaning mechanism.
•Always calibrate and zero the electrode as close to your sample temperature as
possible.
•Always zero the optical electrodes just prior to use in clean water (bottled still
mineral water is ideal) then deploy without disturbing the measurement chamber.
This is especially important when using the Turbidity electrode.
2.5. Important Notes Regarding Long-Term Deployment
Whilst the Aquaprobes feature an effective electrode cleaning system, the Probes should
not be deployed and left for extended periods without regular checking, calibration and
maintenance.
The time period between maintenance visits depends heavily upon the deployment
conditions. For example, if the Probe is deployed in clean water, the only necessity should
be regular single point calibration of the electrodes. This should be done every 4 – 6
weeks.
If the Probe is deployed in water that is polluted, silt-laden or heavily affected by algal
growth, maintenance visits should be much more frequent.
It is very important to keep the cleaning brushes in good condition. The brushes should be
replaced as soon as they show any signs of clogging or deterioration.
Likewise, it is very important to keep the inside of the Probe Sleeve and End Cap clean and
free from any build up of algae or silt.
The Wiper, Probe Sleeve and End Cap all form an integral part of the optical measurement
system. If they are allowed to become excessively dirty, the accuracy of your readings will
be affected.
It is strongly recommended that after initial deployment, maintenance visits are made on a
weekly basis in order to assess the rate of fouling. After several weeks, it should be
possible to establish the optimum time interval for routine maintenance at any given site.
All ion selective electrodes (ISE) exhibit calibration drift over time (around 3% per week).
Drift should not be a major problem where the electrodes can be frequently calibrated.
Also remember, in order to achieve accurate readings with ISE electrodes, the Probe
needs to be placed in flowing water with a minimum flow rate of 0.3m/s over the electrode.
