AP-700 and AP-800 are equipped with commonly used water quality testing sensors on the probes:The standard version of AP-700 can test 9 basic water quality parameters, including pH, ORP ， Conductivity, TDS ，SSG ， Electrical resistivity, salinity, dissolved oxygen, temperature. The standard version of AP-800 adds a turbidity monitoring sensor on the basis of the standard parameters of AP-700, so it can monitor 10 basic water quality parameters, including pH, ORP, conductivity, TDS, etc, SSG ， Electrical resistivity, salinity, dissolved oxygen, temperature, turbidity.

The AP-700 and AP-800 standard packages include a water quality monitor, a 3-meter cable, a GPS handheld device, a range of accessories and calibration solutions, all packaged in a sturdy suitcase for easy storage and transportation.

Metal material:

All probes are made of marine grade aluminum alloy, with a black surface and anodized treatment, which has good corrosion resistance and resistance to biological pollution.

Dissolved oxygen sensor：

Both AP-700 and AP-800Having a sturdy thermocouple methodDO sensor. This solid zinc electrode tip has been improved to have higher cleaning resistance and can be maintained in a dry state. And the tip itself is sturdy and wear-resistant, so there is no need to worry about damaging the function of the sensor.

Additionally,Both AP-700 and AP-800 can choose to upgrade their DO sensors to our optical dissolved oxygen sensors.

Replace turbidity sensor:

The turbidity sensor of AP-800 is installed at the optical sensor port. You can replace this sensor with our other optical sensors.

In addition,AP-700 and AP-800 can also be equipped with an additional depth sensor at the time of booking as required.

Extension cable:

There is one in the standard package3-meter cable. If the actual measurement depth is large and additional length is required, it can also be extended. We have lengths of 10 meters, 20 meters, and 30 meters to choose from. Custom length can also be provided upon request. All cables of 20 meters and above are installed on reels for easier operation.
