Description
The AP-6000, or AP-7000, water quality probes are multi-parameter sensors that come pre-fitted with probes covering pH, ORP, Conductivity, TDS, SSG, Resistivity, Salinity, Dissolved Oxygen, Temperature and Depth sensor. The AP-6000 probe comes with four empty sockets, and the AP-7000 probe with six empty sockets, to add an Optical, or Ion Selective Electrode (ISE) sensors. This page covers the 5 Ion Selective Sensors that can be fitted to Aux Ports on the Aquaprobe sensors. Each adds at least one more parameter to the AP-6000 or AP-7000 probe. Additional 6 parameters covered are: Ammonium; Ammonia; Chloride; Fluoride; Nitrate; or Calcium.
The table below covers the available parameters, with links to get more details on the parameter for each probe.

* Ammonium electrode required. Readings calculated from ammonium, pH and temperature values.
The accuracy figures quoted above represent the equipment’s capability at the calibration points at 25°C. These figures do not take into account errors introduced by variations in the accuracy of calibration solutions and errors beyond the control of the manufacturer that may be introduced by environmental conditions in the field.
The Aux Ports
The AP-6000 probe has four available Aux ports, whilst the AP-7000 has a total of six available Aux ports. Any one of these ports can be fitted with either an Optical or ISE sensor.
