quaprobe® P-700, P-800 & P-2000 Instruction Manual 10401-00870 Rev R
What's New in this Manual?
This Manual, Revision R, covers the new features introduced in 017 with Aquaprobe®
firmware version 4.07 and Aquameter® firmware version 6. 0.
Aquameter and Aquaprobe Firmware
➢Memory storage increased to 10,000 data points. See Memory Mode
➢New Grab Sample Factor setup facility for all fluorescent electrodes.
See Fluorescent Electrode Grab Sample Correction Factor
➢New variable EC calibration point setup facility to allow EC calibration at any value
See EC / Temperature Electrode Calibration and Maintenance
➢New ORP calibration value selection facility. See Calibrating ORP
➢Calibration report values now stored with each data point with new screens to view
report values for every parameter. See Calibration Data Storage and Retrieval
➢New Probe temperature sensor calibration screen. See Calibrating Temperature
PC Software
Both the AquaLink (Version 5.00) and AquaCal (Version .00) PC applications have been
upgraded to take full advantage of all the new features listed above. The latest versions
can be downloaded free of charge from http://www.aquaread.com/downloads.php
Not Running the Latest Firmware?
All the new firmware featured in this manual can be retrofitted to any existing metal
connector type Aquaprobe® (regardless of current firmware revision) and to any Aquameter
currently running firmware version 4.50 or above.
In order to have access to the new features, both the Aquaprobe® and associated
Aquameter® must be upgraded together.
Aquameters currently running firmware revisions lower than 4.50 can not be upgraded due
to lack of sufficient memory space.

quaprobe® P-700, P-800 & P-2000 Instruction Manual 10401-00870 Rev R
1. Introduction
This manual specifically covers the setup, operation, calibration and maintenance of
Aquaprobe® models AP-700, AP-800 & AP- 000 running V4.07+ firmware, Aquameter®
models running V6. 0+ firmware, AquaLink V5.00+ PC software and associated
Aquaprobe® accessories. If your Aquaprobe® or Aquameter® are 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.
Calibration bottle filled with RapidCal Solution.
Spare calibration / rinse bottle.
One mounting nut (pre-fitted).
Getting started card for quick reference.
5mL bottle of pH storage solution.
Pot of silicone grease.
Spare Galvanic DO Membrane Cap (AP-700 & AP-800 only)
5mL bottle of Galvanic DO filling solution (AP-700 & AP-800 only)
If using an AP- 000, you will also need an AP- 000 Extension Cable, which should be
purchased separately.
2.1. The Aquameter and the Environment
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 Environment
The Aquaprobe® AP-700 and AP-800 models 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 10
meters, and short term immersion (less than 1 hours) to a depth of 50 meters.

quaprobe® P-700, P-800 & P-2000 Instruction Manual 10401-00870 Rev R
The Aquaprobe® AP- 000 and AP- 000-D models 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.
2.3. Important Information about the Probe Sleeve & Sleeve End Cap
The Aquaprobe® is 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 forms an integral, working part of the
Probe’s measurement system, and MUST be fitted for correct operation.
Probe sleeves are also specifically matched to the Probe with which they were
supplied. If you have more than one Aquaprobe , be sure not to mix the sleeves up
between the Probes. Doing so may seriously affect the performance of the EC
electrode.
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 Aquaprobe®
is 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.
This is essential for the
correct calibration and
operation of all types of
optical electrodes.
A diagram of the Aquaprobe’s
measurement chamber is shown
here.
In order to obtain consistent results, the measurement chamber created within the
Aquaprobe must remain physically constant during both calibration and
measurement.
If the 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.
