Sigrist absorption meters provide valuable information in the ultra-violet or visible region at one or more wavelengths. This allows the user to determine the concentration of substances such as metallic ions or organic compounds in liquids or gases or the color of liquids.
1. ColorPlus 2 In-line
Absorption Measuring Instrument in-line.
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.
The Ozone meter for gases measures the ozone concentration according to standard DIN 19627 and the IOA (International Ozone Association) at a wavelength of 254nm. According to these standards, the extinction coefficient is 3024 l/mol cm. Therefore, the ozone measurement can be regarded as an absolute measurement requiring no calibration with ozone. Special measuring cells with different path-lengths cover measuring ranges for low as well as high concentrations. The concentration readings (e.g. in g/m3) are valid for the pressures and temperatures prevailing during measurement. For the conversion to standard conditions, an external pressure and temperature sensor can be connected to the operating unit, die calculation is then automatically done within the instrument.

With the ColorPlus 2, the ozone concentration in ultrapure water (UP water) can be determined directly and without interference. The device measures the absorption at 254 nm. The optical measurement guarantees a fast response time. The device is supplied with a secondary unit to check the calibration. Other checking units can easily be used. The SICON control unit is also included in the scope of delivery. Values can be visualized and read out directly and with a variety of settings and communication options, system connection is simple.
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.
UV absorption is an indicator of water pollution by certain dissolved organic substances, such as aromatic compounds or humic substances from the soil.

The instrument is used in the treatment of drinking water as well as in the treatment of process water in various kinds of industries.
Absorption measuring Instrument bypass for hazardous areas.
The ColorPlus is built to accommodate up to three different light sources (UV and visible range) for the measurement of color, DOC and concentrations. By use of the dichromatic measurement at separate wavelengths the turbidity can be compensated. Measurements are performed inline or in bypass cells, the selection of materials for the cell and housing depends on the requirements. A version with flameproof encapsulation is offered for installations in areas requiring explosion.
