Multiparameter Probes for Aquaculture, AP-700, AP-800, AP-7000
A multiparameter water probe measures several water quality parameters at the same time, from a single immersion. The Aquaread range covers everything from basic packages, suitable for daily checks, to probes for long-term monitoring, with a self-cleaning system.
- AP-700, the "big four": oxygen, conductivity, pH, temperature
- AP-800, everything included in AP-700, plus a turbidity sensor
- AP-7000, long-term deployment, self-cleaning, up to 17 parameters
What Is a Multiparameter Probe?
A multiparameter probe is an instrument that measures several water parameters at the same time, usually dissolved oxygen, conductivity, pH, temperature and, depending on the model, turbidity. The sensors are grouped into a single submersible probe, so one reading gives a complete overview of water quality.
Compared with individual sensors, a multiparameter probe saves time and reduces the number of devices that need calibration. In aquaculture, the advantage is that you can see all relevant parameters in one single data set
AP-700 and AP-800, Basic Packages
AP-700 and AP-800 are complete packages for basic monitoring. They include the probe, GPS Aquameter handheld device, 3 m cable, accessories, calibration solution and a carry case. They are suitable for farms that need a reliable set of essential parameters, without complicated setup.
AP-700, the "big four"
Dissolved oxygen, conductivity, pH and temperature, plus ORP, salinity, TDS and resistivity. For freshwater applications.
Low Maintenance
Infrequent calibration, every 3 to 6 months, and replaceable caps with a lifetime of over 2 years.
AP-7000, for Long-Term Deployment
AP-7000 is a multiparameter probe for long-term monitoring, with a self-cleaning system that reduces biological deposits. In addition to the standard parameters, including optical dissolved oxygen and depth, it has 6 sockets for additional sensors and can measure up to 17 parameters simultaneously.
AP-7000 has a central self-cleaning brush system, which wipes the sensor faces several times per cycle and reduces the effects of biofouling, common in long-term deployments.
The 6 configurable auxiliary sockets accept any combination of ion-selective or optical sensors. It is used with AquaConn cables of 3, 10, 20 or 30 m, depending on the installation.
Comparison, How to Choose
In simple terms: choose AP-700 for basic parameters in a freshwater farm; AP-800 when you also need turbidity; AP-7000 when you need continuous monitoring, more sensors and long-term installation.
| AP-700 | The big 4 + ORP, salinity, TDS, resistivity, portable, freshwater |
|---|---|
| AP-800 | AP-700 parameters + turbidity, portable, water clarity |
| AP-7000 | Standard parameters + optical DO + depth, 6 sockets, up to 17 parameters, fixed, long-term |

FAQ
What is the difference between AP-700 and AP-800?
Both are basic packages with the same essential parameters, dissolved oxygen, conductivity, pH, temperature and others. The difference is that AP-800 adds a turbidity sensor with a sapphire lens. If monitoring water clarity is important for your application, AP-800 is the right option.
How many parameters can AP-7000 measure?
AP-7000 comes with a standard set of parameters, including optical dissolved oxygen and depth, and has 6 auxiliary sockets for additional sensors. When fully configured, it can measure up to 17 parameters simultaneously, depending on the sensors installed.
Which probe is suitable for continuous monitoring?
For continuous monitoring, AP-7000 is the choice in this range, thanks to its central self-cleaning system, which reduces biological deposits and allows long-term installation. AP-700 and AP-800 are better suited for portable, periodic measurements.
Do I need a separate device for calibration?
Yes. For sensor calibration and field readings, you need the GPS Aquameter handheld device or an equivalent alternative, such as the Bluelink adapter. This is included in the AP-700 and AP-800 packages.
