1. |
In addition to the standard parameters supplied with the base Aquaprobe, the AP-2000 has 1 ISE port and 1 optical port, the AP-5000 has 4 ports that can take any combination of ISE or optical sensors and the AP-7000 has 6 ports that can also take any combination of ISE or optical sensors. |
2. |
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. |
