• Absolute EC
• pH
• ORP
• TDS
• Resistivity

The AP-700 offers “the big 4″ commonly known as pH, EC, dissolved oxygen and temperature whilst the AP-800 offers more with the addition of our compact sapphire lensed, nephelometric turbidity sensor built in.

Add More to Your Aquaprobe

In addition to these basic parameters there is also the possibility to upgrade the DO sensor to an optical DO sensor and there is the option to add a depth sensor to the probe. Prices for these upgrades are available on request.

Our latest tough DO sensor design

Our galvanic DO sensor tip has been modified to give an increased resistance to cleaning, allowing it to be easily maintained if the sensor is allowed to dry out.

The Tip itself features a solid zinc block that can be polished without fear of damaging the sensors functionality.

Replaceable Sensors

We can replace all sensors

All of the sensors on the AP-700 and AP-800 are replaceable. pH/ORP and turbidity sensors are user replaceable, where as the Dissolved oxygen, conductivity and temperature sensors are all factory replaceable.

Accidents can happen in the field and the ability to replace sensors should they get damaged, will help keep your system working for longer

Save Over 40%

The AP-700 water monitoring package is over 40% cheaper than our more advanced AP-2000 Package. Whilst the AP-700 might not feature our optical dissolved oxygen sensor but the sensors specifications in terms of accuracy and resolution are identical. The AP-700 package is the ideal place to start out if you are new to water quality monitoring. It outputs a combination of 9 measured and calculated parameters directly from the probe, and a further 2; air pressure and GPS coordinates, when used with the GPS Aqmameter.
