AP2000 Multiparameter Probe

• Probes come as standard with an advanced optical DO sensor, Conductivity, pH/ORP and Temperature
• Option to add depth measurement
• Extra sensor ports allow users to insert 1 ISE and 1 optical sensor or 2 ISE sensors
• Probes have a built in connector allowing quick and easy cable exchange
• Submersible to up to 100m
• No flow of water required for stable reading, making it ideal for deployment in still waters
• Reduced maintenance
• Holds calibration for up to 6 months and does not need cap and solution replacement
• Reduced membrane fouling optimises sensor for long term deployment
• Probes are available with a built in depth sensor (AP-2000-D)
• Fully compatible with Neon telemetry data loggers
• SDI-12 compatible
• Modbus (RS-485) output

The AP-2000 is the smaller of the advanced portable multiparameter water monitoring probes. It comes with a range of standard sensors included, it also offers some customisation options that allow you to add even more sensors to the probe. All Aquaprobes are constructed from tough marine grade aluminium that has been hard anodised, making it suitable for use in both fresh and salt waters.

Readings can logged with standard data loggers or transmitted in real-time using Neon web-based, telemetry data loggers. Readings can also be displayed on the GPS Aquameter.

As an option, the AP-2000 can be supplied with additional SDI-12 and Modbus (RS-485) outputs to allow direct connection to a wide range of data logging and telemetry equipment. This option facilitates direct replacement of existing probes made by other manufacturers.
