Nitrate measurment
Bypass Absorptionmeter Nitrate Nitrates are nitrogen compounds that occur naturally in the soil, but also enter the soil as a component of fertilizers. Even a small amount of nitrate in drinking water can pose a health risk! Sigrist ColorPlus 3 offers you online measurement of nitrate. As a light source, a long-lived xenon flash lamp is used having a very low loss of intensity over a long time! The medium is measured with two optical path lengths from which any soiling is determined. The value measured is automatically corrected and the instrument informs the user when the measuring cell has to be cleaned. The PVC cover can be removed without tools. Free access to the optics allows simple cleaning of the measuring cell. The instrument indicates any maintenance due. The control unit SICON selectively displays values, graphs, status and alarms on state-of-the-art touchscreen technology and colour display. Internal data storage allows the visualization of the measurements over the last 32 days. The instrument is used in the treatment of drinking water. Features Uniform, precise measurement Simple, tool-free maintenance. Compensation of window soiling Service life of light source: 10 years
Automatic flow cytometer for microbiological monitoring of water
The BactoSense is a fully automatic Flow Cytometer for continuous on-line monitoring of the amount of microbial cells in a process. The compact instrument is designed to provide a quick insight into the general microbiological quality of a liquid. Result aer available within 20 minutes. The biological “fingerprint” of a fluid and cell-size ratio (LNA/HNA) provide an instant insight into the biological change. Thresholds can be monitored and alarms generated automatically. Compared to plate counting (HPC), the result is much faster, more realistic and more comparable. A completely sealed cartridge is used. No chemicals and waste handling is required. This guarantees safe operation at all times. Cartridges are available for Total Cell Count (TCC) and Intact Cell Count (ICC). Even with a relatively small number of samples, the BactoSense is cost effective.
AquaScat S - In-line turbidity measurement for the water treatment
In-line turbidity measurement for the water treatment The AquaScat measures the turbidity of potable water according to IEC 27027, with the measurement carried out directly in the water. This reduces maintenance work to a minimum. The calibration is done with a checking unit that is installed when needed. Various customer wishes can be catered for with the different options for data visualization and connection to a PLC/SCADA. Thanks to the different process integration options, a solution can be found for virtually any requirement.
AquaScat WTM (A) en HT - Turbidimeter (ISO 7027) with free fall flow cell with high resolution
On-line Turbidimeter (ISO 7027) with free fall flow cell with high resolution The AquaScat measures turbidity of potable water according to IEC 27027 using 90+° scattered light detection in a free-falling water stream. This contactless design eliminates window foiling and minimizes servicing to a minimum. Calibration check is performed with a calibration unit that is either mounted to perform the check or that is already built in (depending on variant).
AquaScat P - Turbidity meter
On-line Turbidimeter (ISO 7027) for pressurized measurement The AquaScat measures turbidity of potable water according to IEC 27027 and is specially designed for installations with highly gaseous water under pressure. Calibration check is performed with a calibration unit with a glass reference that is mounted when performing the check.
Colorplus 2 - Absorption Measuring Instrument
The ColorPlus measures the colour/absorbance online at up to three different wavelengths in the UV and visible range, also combined. Turbidity can be compensated at the same time by selecting an appropriate wavelength. The modular design of the instrument enables to cover various applications by selecting the most suitable measuring cell. In many cases, a standard housing like e.g. Varivent® is used. Alternatively, custom-specific flow cells in different materials and designs are available. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control. Applications - DOC (UV absorption) measurement - Colour (Hazen) measurement - Measurement of the elimination of micropollutants Properties - Combined online measurement of DOC (UV absorption) and colour (Hazen) in one instrument - Optical compensation of window soiling - Dual beam measurement for high stability - Flow cell easy to clean without tools - Fast and simple verification with control unit - Turbidity compensation by means of an additional light source (optional)
ScrubberGuard - Measuring system for scrubber wash water monitoring
More and more goods are transported by sea on a global scale and cruise liners are also enjoying an increase in popularity. For economic reasons, many ship operators choose heavy fuel oil as a propellant. The International Maritime Organization (IMO) has issued guidelines for limiting pollutant emissions of heavy fuel oil powered ships. In order to continue an operation with highly sulphurous heavy fuel oil, the ships are refitted with scrubbers. The certified measuring system ScrubberGuard reliably and continuously measures the parameters of the scrubber wash water, such as turbidity, oil-in-water, pH and temperature in accordance with the guidelines for exhaust gas treatment systems MEPC.259 (68). The true non-contact measuring system and the exact recalibration (you can do on your own) without the use of chemicals, allows a long-term stable measurement and reduces maintenance to a minimum. The ScrubberGuard was specifically designed for the challenging process and environmental conditions of this application.
Olie in water analyser
The instrument is used for monitoring oil traces in raw, surface, process and waste water. As a result of the non-contact free-fall measurement, there are no reading falsifications arising from window soiling and there is an extremely low need for maintenance. The instrument’s factory setting is calibrated with 16 EPA-PAH standard. The OilGuard 2 W can be recalibrated by the customer with a secondary standard (solid reference) which allows an exact recalibration without 16 EPA-PAH. The ingenious instrument design of the OilGuard 2W in combination with the high quality of its optical components minimizes the effect of interferences. Thus, even the smallest traces of oil, as well as larger amounts, can be precisely detected. The instrument can be adapted to various types of oil to meet customer requirements. Checking the instrument is easy with corresponding solutions.
