NEP-495 Turbidity Logging probe
The ANALITE NEP-495 microprocessor based turbidity probe is designed for monitoring and logging applications where turbidity levels of up to 3,000NTU may be encountered. The ANALITE NEP-495 probe, with its integral wiper assembly, is designed to operate over an extended period of time where bio- fouling or sedimentation build-up is likely to be encountered. The ANALITE NEP-495 Turbidity Logging probe may be submerged to a depth rating of 100 meters (approx. 330 feet).
The ANALITE NEP-495 Turbidity Logging probe use 90° optics and employs infrared light in accordance with ISO7027 and use a unique modulation technique that ensures almost total rejection of ambient light conditions.
The user may calibrate the probe at any time via the USB interface and PC software.
The ANALITE NEP-495 Turbidity Logging probe is similar to the ANALITE NEP-395 probe but with the inclusion of temperature measurement and a flexible self- contained logging function. As normally supplied, the ANALITE NEP-495 can store over 30,000 data sets with each data set consisting of turbidity, temperature, time and date. Logging intervals can be set from less than 1 second to over 18 hours. Data is stored in non- volatile memory.
The ANALITE NEP-495 is self-contained requiring no external power or commands once logging has commenced. The internal batteries have a life expectancy of over 30,000 data sets or about 60 days (whichever comes first), assuming a wipe prior to each reading.
Each logging point generates a data set containing:
