NEP-5000 Digital sensors

The ANALITE NEP-5000 ISO7027 90°series of digital turbidity probes are designed for monitoring and process applications where ultimate sensor flexibility is a consideration.


Product Description

NEP-5000 Digital sensors

Our successful NEP-5000 family of ANALITE turbidity sensors offers enhanced performances in a small and revolutionary design with greater ease of deployment at lower cost. The NEP-5000 Digital sensors are designed for monitoring and process applications where turbidity levels of up to 5,000NTU may be encountered. Standard ranges are 10NTU, 400NTU and 5,000NTU, but custom ranges are available. The NEP- 5000 Digital sensors are designed for applications that will not allow bio-fouling to build up such as short monitoring deployment or placement in fast and cold running water. The NEP- 5000 may be submerged to a depth of 100 meters (approx.. 328 feet).

The NEP-5000 turbidity probes use 90° optics and employs infrared light in accordance with ISO 7027. All probes use a unique modulation technique that ensures almost total rejection of ambient light conditions as well as a unique microprocessor controlled differential sample and hold circuit for enhanced performance particularly at low turbidity levels.

This product is ideal for portable application, as well as field and laboratory applications for long term monitoring. Simple to operate, NEP-5000 can be customized and upgradeable. Data logging can also be performed using application on your Windows Tablet using Bluetooth communication.

The new NEP-5000 series of turbidity sensors also has the added benefit of a self- cleaning, auto-ranging field instrument. The system can be cabled or directly connected to the wireless module for quick field process reading.
