1 SUSPNDD SOIDS NYZR Model SSF-6 The SSF-6 is an analyzer used to conduct continuous optical measurements of the concentration of solids. It can measure the concentration of suspended solids (SS) in sewage, night soil, and industrial waste treatment plants, as well as the concentration of mixed liquor suspended solids (MSS) in aeration tanks. The SSF-6 consists of a small lightweight infrared detector, which is designed to be immersed in sample solutions, and a transmitter for converting the measured SS concentration to 4 - md analog output signals and RS-485 digital signals. Features xtensive measurement ranges The SSF-6 can conduct measurements across wide concentration ranges, such as ranges of - mg/ (ppm) and - mg/ (ppm). You can choose a - range type or a -range type. There are selectable modes for switching, manual ranging, auto ranging and remote ranging for each model. Infrared detector The light source of the SSF-6 is an infrared lightemitting diode (D). This D is long lasting and is almost completely unaffected by colored samples. In addition, the pulsed light signals processing prevents it from being affected by sunlight and other forms of ambient light. Practical calculation features The SSF-6 comes with useful features for calculation functions. The unit employs piecewise linear approximation to correct values that were analyzed manually. It also performs -point calibration to correct approximate calculations. nd self-diagnosis including system error, calibration error and others is available. Detector options: Throw-in type and drop-in type Detectors are classified by installation conditions into Drop-in type detector different types: throw-in type and drop-in type, the latter in which the detector is inserted into a long protection pipe that is - 6 meters long. Stain-resistant design The small and lightweight detector is made of stainless steel and has a stain-resistant design. The detector plane is washed by the flow of sample water, which helps to prevent dirt deposits from accumulating. Jet cleaner (option for the drop-in type) water (air) jet cleaner or pulse air jet cleaner can be purchased as an option to remove thick layers of dirt deposits that form on the detector plane, such as when the flow rate of sample water is too slow.

Thus, calibration using manual analysis data at each site is required. ) alibration using manual analysis (weight method) as standard onduct manual analysises (weight method) and record SSF-6 readings for as many samples as possible. Plot the regression line on the scatter diagram by comparing the manual analysis values to the SSF- 6 readings. Using this regression line, calibrate the instrument. )Using the standard scatter plate to perform calibration fter calibration using manual analysises (weight method), measure the supplied scatter plate and record the indicated values. Then calibration using the scatter plate will be available. ontact input Repeatability Stability Response time *: If automatic or remote is selected as the range switching mode for the -range type, contact points are used exclusively to display the range. : Remote range switching, cleaning command : ±% FS (with standard solution) : Zero drift; ±% FS/7 days (with zero water) Span drift; ±% FS/7 days (with standard solution) :5 minutes or less for 9% response when set at position 4.

Detector installation conditions void installing the detector in a location where the sample flow rate is slow or stagnant. If a thick layer of dirt deposits forms on the detector plane of the drop-in type, we recommend that you purchase the optional water (air) jet cleaner or pulse air jet cleaner to remove the deposits. Note that samples containing dissimilar metals (particularly iron) can cause crevice corrosion. If corrosion occurs after installation, we recommend covering the unit with anti-corrosion zinc tape (code No. 48).
