Description
The AP-2000 water quality probe is a multi-parameter sensor and comes pre-fitted with probes covering pH, ORP, Conductivity, TDS, SSG, Resistivity, Salinity, Dissolved Oxygen and Temperature probes, the AP-2000-D add a depth sensor. Each probe comes with two 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 Port 2 on the AP-2000 probes to add one more parameter to the 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 AP-2000 Aux Ports
The AP-2000 probe has two available Aux ports. Aux Port 1 can be fitted with either an Optical or ISE sensor. Both ports can be used with any of the five ISE sensors to add any of the six parameters. The AP-2000 Optical Electrodes can be found on the link below.
