The Sensor measures: Water Flow
Cable Length: 3m
Sensor for use in: Water Quality

The AP-2000 is the smaller of our advanced portable multiparameter water monitoring probes. It comes with a range of standard sensors included, it also offers some customisation options that allow you to add even more sensors to the probe. All of our probes are constructed from tough marine grade aluminium that has been hard anodised, making it suitable for use in both fresh and salt waters.

Standard parameters on the AP-2000

     Optical DO
     Specific EC
     Absolute EC
     pH
     ORP
     TDS
     Resistivity
     Salinity
     SSG
     Temperature

Customization Options:

The AP-2000 features 2 Auxiliary sockets to allow you to add further sensors to the probe.

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

Customisation Options

There are 3 simple choices to make to customise the probe.

The probe comes with 1 Ion Selective Electrode (ISE) socket and 1 optical electrode socket, plus an option to add a depth sensor!

Probes are supplied with blanking plugs in the ISE and optical electrode ports as standard. Simply unscrew these to add your extra electrodes.

Using the AP-2000-D as a water level logger

The AP-2000-D features a depth sensor. This sensor is capable of measurement accuracy of 0.5%FS.

This is very comparable to a dedicated water level logger such as the LeveLine-ECO: 0.2%FS, and the LeveLine (titanium): 0.1%FS.

The depth is zeroed automatically whilst the conductivity is reading zero. As soon as the conductivity registers over 0 the probe depth begins to be calculated.

Once the probe is lowered to the desired depth it must be secured, then using the GPS Aquameter the depth can be zeroed once again.

Now the AP-2000-D will detect small changes in the water level and display them as a positive or negative change.

AP-2000 Mechanical Specification

AP-2000-Spec

Advanced Optical DO sensor

The optical sensor works on the principle of Dynamic Luminescence Quenching. A gas-permeable material known as a luminophore is excited with short bursts of blue light, which causes molecules in the luminophore to emit red photons.

By measuring the delay of the returned red photons with respect to the blue excitation, the level of dissolved oxygen present can be determined.
The optical method has various advantages over the historical galvanic method for measuring dissolved oxygen.

The most important being that as no oxygen is consumed across a membrane, the sensor does not require a flow of liquid passing over it to achieve a stable reading. Other advantages include in frequent calibrations (every 3-6 months), and replaceable caps that last over 2 years.

Rugged Connection

All Aquaprobes feature the new AquaConn fully metal connectors. The AP-2000 features the all-metal AquaConn connectors.

These high specification connectors feature large metallic key for a rigid fit, recessed pins for extra protection during pairing, guide markers on each part of the connector to allow you to instantly push the pair together in the correct alignment.
