  • Page 9: Applications

    Which model is best used will be dependent on the application, the measuring environment, the logging equipment and the monitoring period (deployment times) required. Although advanced digital processing in the ANALITE NEP-5000 will effectively measure the true turbidity of water when large particles are passing by the optical face, it is recommended to take steps to protect the optical face from possible abrasive effects these particles may cause.
