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 NKE AM-200 GPS Aquameter is the original handheld water quality meter with built-in GPS. The built-in GPS receiver allows the meter to record the location of every dataset, meaning you will always know where your data was captured. The meter is designed to be picked up and used by anyone intuitively. It requires no boot-up or warm-up time and allows you to record data with a single button press.

• 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.

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

Find out more about our AquaProbe Electrodes Even if you will be using your Aquaprobe with an AquaLogger or other device, you will still need a GPS Aquameter. The meter gives you real-time readings via the display, which are useful when deploying your logging system, as it allows you to check that the parameters are all reading ok.
