The ANALITE turbidity probe is available in standard ranges of 100NTU, 400NTU and 1000NTU with specific custom ranges available for up to 3000NTU. The NEP390 series of turbidity probe offers digital outputs of SDI-12 and/or RS232.
The ANALITE NEP9000 non wiping probes are specific to fast and cold running water or in short monitoring deployment applications where bio-fouling will not build up and obscure the optics. However, if bio-fouling or sedimentation build up is likely the ANALITE NEP9500 probe is the ideal model. It comes complete with an integral wiper assembly specifically designed to cope with bio-fouling or sedimentation build up. Standard ANALITE NEP9000 and NEP9500 series probes with their acetal housing are fully functional to the submerged depth of 50 metres (165 feet). If a greater depth of up to 100 meters (330 feet) is required there is the option of stainless steel housing. This is not recommended for deployment in salty or acidic water due to possible impact of crevice corrosion.
The ANALITE NEP9000 and NEP9500 probes use 90⁰optics and infrared light in accordance with ISO7027. Unique modulation techniques almost totally reject ambient light conditions along with a unique microprocessor controlled differential sample and hold circuit for enhanced performance particularly at low turbidity levels.
The ANALITE NEP9000 and NEP9500 probes are suitable for an extensive range of applications however, the model and option which is best suited is dependant to the specific application, the measuring environment, the logging equipment and the monitoring period/deployment times required.
