The NKE Aquaprobe AP-6000 Water Monitoring Probe can be used for comprehensive spot monitoring as part of a package, or it can be used in permanent deployments thanks to its new, much smaller self-cleaning mechanism. It features a diameter of only 58mm (the same size as the AP-5000), making it our smallest self-cleaning Aquaprobe to date.

The NKS BlueLink Bluetooth Device for Connectivity to the Aquaprobe & PRO Range of Water Quality Probes is an adaptor that replaces the Aquameter in your portable monitoring setup. It connects to the end of the Aquaprobes cable, features a rechargeable battery and Bluetooth communications.

The Bluelink app will allow you to view live data from the probe, to calibrate all of the sensors on the probe, to assign the sockets if you have additional sensors fitted to the probe and to automatically log data. It will have all of the features of the Aquameter

• The AP-6000 features 4 Auxiliary sockets to allow you to add further sensors to the probe. Unlike the AP-2000, these auxiliary ports are unrestricted. This means that each port can take either an Ion Selective Electrode (ISE) or an optical sensor. This makes the number of potential sensor combinations vast.


• The probe can be used with a variety of cable lengths via the AquaConn Connectors. Cables available in 3, 10, 20, and 30m lengths as standard.

• The new, smaller removable central cleaning arm of the AP-6000 consists of a rotating set of brushes that clean all of the connected sensors, including the EC sensor located on the side of the optical DO probe. The cleaning arm, which features a small motor inside, can be easily unscrewed for maintenance, brush replacement, and cleaning. Wiping the sensors regularly in this way can increase the deployment duration substantially, even in demanding environments.


• The main advantages of the AP-6000 are its versatility and its price point. The Aquaprobe is small enough to be used portably as part of a package including a carry case, but it can also be used with an Aqualogger or with telemetry if you require a more determinant monitoring solution.

Each sensor serves a unique purpose, and so is unique in its function and composition — but all are made with high-quality, durable materials that allow you to measure accurately, time and time again.

If you’re not sure what water quality testing sensor you need, do feel free to contact us to discuss your specific requirements..

Some of our most commonly-used sensors include:

• pH — to measure water acidity


• Temperature — to measure temperatures between -5 and +50°C


• EC — Electrical Conductivity — to measure the concentration of salts


• Turbidity — to measure water clarity impacted by the presence of suspended particles


• DO — Dissolved Oxygen — to measure the level of oxygen in the water

The NKE Bluelink Bluetooth Water Quality Monitoring Adapter is made from aluminum and carbon fiber and houses a rechargeable battery. The unit also features a barometric pressure sensor for live compensation of the dissolved oxygen and depth measurements.

The internal battery within Bluelink is rechargeable. It is supplied with a USB charging cable, meaning it can be charged from your PC, USB wall plug, or a portable battery with USB sockets.

The Bluelink module can only be powered with a cable connected to it, preventing the device from draining if left switched on when the cable and probe are disconnected.

Open up the Bluelink app on your device after switching on the Bluelink unit. The app will start in the ‘add new device’ screen and auto-detect the Bluelink unit, click on it to pair. Previously paired probes will appear here to make it quicker to connect.

Bluelink brings your water quality data direct to you phone via the app, which is available to download on both Android and Apple devices from the relevant app stores, follow the links below to your preferred store.

Once you have connected your Aquaprobe to the Bluelink device, you can configure any extra sensors you have added to the probe, check Bluelinks battery level, check software versions and model numbers

By selecting the options menu you can and tabs to view the live data coming from with, options to customise which parameters are visible. Calibration, where you can view GLP calibration data and perform new calibrations. Logs, where any logged data recorded via the app will be located and settings where things like temperature units can be changed or EC compensation can be adjusted.
