Whatever level of suspended solids from 2 NTU all the way up to >8% solids, the Chemtrac TSS Monitor is the solution. A sophisticated sensor that ranges up to 8% solids (in wastewater, and up to 50% in other solids), this suspended solids monitor is the solution, and is unique in its ability to measure from low NTU to percent solids in one sensor.
Suitable for wastewater, potable water monitoring, mixed liquor suspended solids monitoring, return activated sludge, centrate monitoring, filtrate monitoring, sludge, and many more applications where a traditional turbidimeter or suspended solids analyzer would be used. The suspended solids sensor can be fitted with an auto-cleaning function that blasts either water or air across the optical windows keeping them clean.
With the Chemtrac Suspended Solids monitors you get a world class sensor (patent applied for).
The suspended solids analyzer has been designed specifically to be suitable for all wastewater applications.
Inlet monitoring (turbidity 2-4,000 NTU)
Effluent monitoring (suspended solids 0-1,000 mg/l)
Traditional monitoring applications where the TSS monitor is particularly suited:
By using two detectors in a single probe it is possible to:
The electronics provide a fully scalable output allowing the TSS analyzer to measure any part or the whole of the scale. The sensor probe comes equipped with the capability of having a water jet regularly sweep over the optical lenses keeping them clean. If you have an application that ranges from low NTU all the way to % solids then this is certainly the suspended solids monitor for you! With up to 5 calibration points you can accurately monitor your process across a wide range of sample concentrations.
The probes are constructed of 316 stainless steel with sapphire optical windows, so they can withstand demanding operating environments. If you want to monitor solids at any point in your wastewater treatment plant, this instrument has the self-cleaning sensor and accessories to do it, even if other instruments have failed.

Each suspended solids monitor is fitted with a light source and two detectors for making the measurements. Having two detectors, positioned at different distances from the light source, allows the sensor to be used over a wide range of suspended solids concentrations. The light source is a long life infra-red LED emitter (providing for 15 years working life). The detectors are matched photodiodes that are positioned to detect backscattered light, which is light that is scattered by >90°. By measuring back scattered light the sensor can be used to detect low and high concentrations of solids. This configuration allows accurate and reliable measurements of suspended solids concentrations and turbidity to be made.
Calibration of the TSS sensor for turbidity measurements (NTU) or measurements of samples with low concentrations of solids is very easy, requiring a single calibration sample. This sample can either be a reading from another method, or a suitable standard. The analyzer calibrates the sensor by a procedure that reduces the light output through four stages, taking measurements at each. This process provides an accurate and reliable zero and span without the requirement to use a ‘0’ NTU/solids sample.
The calibration of the TSS sensor for the measurement of samples with high concentrations of solids uses a multi-point calibration for the most accurate results. Up to 5 calibration points can be used to give an accurate performance across a wide range of sample concentrations.
The TSS sensor can be mounted on the end of a pole for dip mounting in a channel or tank, or inserted into a pipe via a valve which allows for retraction/removal of the sensor without shutting down the process.
The Chemtrac suspended solids sensor is available with different controllers giving you the same great performance with different communication, display, and control options. With the Chemtrac range of online suspended solids analyzers, you get everything that you need – and nothing that you don’t, without sacrificing the quality of measurement.
The use of a single sensor to robustly and accurately measure a large dynamic range of suspended solids allows for:
