NEP-695 logging probe

The NEP-695 is an all-in-one device that contains a scriptable SDI-12 logger with an integrated rechargeable battery designed for long-term operations.

The system is cased in a fully water-sealed housing that can support up-to 50 meters of water pressure.


Product Description

NEP-695 long life logging probe

Designed to be fitted with the NEP-5000 SDI-12 option, the NEP-695 is a logging solution to monitor the turbidity. The NEP-695 has a built–in 6-pin female Subconn connector as a sensor interface. It provides the ability to connect multiple SDI-12 sensor networks to monitor several water quality sensors.

Built-in logger

The NEP-695 contains the OEM CR300 logger by Campbell Scientific. This is a proven working solution by many ANALITE customers, which will provide a scriptable logging capability.

Built-in rechargeable battery

The main advantage of having a built-in rechargeable battery is its low running cost. Hence, users are not required to buy expensive batteries.

Built-in Lithium-ion batteries have a capacity of 144Wh which can be charged via simple DC plug- pack or solar input. Thus, providing ideal dropping solution for data-buoys and river monitoring applications.


When using the battery on its own, with the NEP- 5000 sensor, the system is capable of measuring 27,000 measurements. This is approximately 5 months in 10 minute-intervals or indefinite use when connected to a 20W solar panel.
