KISTERS AG products

KISTERS multi-parameter water quality probes HyQual 200, HyQual 300 and HyQual 300T are your individual complete solutions in water quality analysis. Depending on the chosen model and optional extensions, the sensors can determine a subset or all of the following parameters:

TriOS`s new low-cost nitrate meter Based on the device platform concept of TriOS sensors like OPUS, LISA and VIPER, TriOS introduces NICO: a low-cost UV photometer for the determination of nitrate. The four detection channels enable a precise optical determination of nitrate by absorption, taking into account turbidity and organic substances that pose a problem for many products currently on the market.

The TTurb is a digital sensor for optical turbidity measurements according to the 90° IR scattered light method. Depending on the sensor it can be used in pure water up to 100 FNU as well as in raw-, waste- and process waters up to 1000 FNU. TTurb is available with a 10 m or a 2 m fixed cable.

Conductivity sensors are measuring devices that measure the ability of a measuring medium to conduct electric current between two electrodes. The current flows by ion transport. This means that measuring media with a higher number of ions conduct the current better. A conductivity detector is used for digital measurements of conductivity in pure or process water.

The oxygen sensor uses luminescence-based optical measurement technology and measures reliably and precisely. The low maintenance and small amount of consumable materials needed by the sensor provide immediate returns on investment. Only the membrane cap must be replaced every two years. The sensor can also be used in applications with a very weak water flow. The oxygen sensor is available with a 10-meter or a 2-meter cable.

Robust digital pH sensor for operation on TriBox controllers and HS100 DIN G2 rail module. Digital communication provides safe and trouble-free signal transmission from the sensor to the controller. The high-quality gel pH electrode has a hole diaphragm and is insensitive to dirt, making the sensor ideal for wastewater applications.

OPUS is the new generation of spectral sensors for online measurement of nitrogen and carbon compounds. Through the analysis of a full spectrum, OPUS is able to deliver reliable readings for NO3-N, NO2-N, organic ingredients (CODeq, BODeq, DOCeq, TOCeq), and a number of other parameters. OPUS features the new TriOS G2 interface, allowing fast and easy configuration of sensors by using a web browser. 

Our high-end matrixFlu VIS fluorometer combines multiple excitation and detection wavelengths for fluorescence meas urements in a single device with a highly compact design. The special optical arrangement of excitation and detection channels enables not only single values to be determined, but also a 4x4 matrix of wavelength combinations. This allows quasi synchronous in-situ detection of EEMs (Excitation Emission Matrices).

nanoFlu fluorometers are low-priced, submersible miniaturized fluorometers for highly precise and selective measurement of CDOM (colored dissolved organic matter, yellow substances), chlorophyll a or phycocyanin in cyanobacteria. Long-term stability of measurements is achieved by the combination of low power consumption and innovative coating of the optical window, as an energy efficient and environmentally friendly anti-fouling solution. The devices can be used in diverse applications for the monitoring of sea and river waters, as well as in drinking- and wastewater treatment systems. Internal reference signals of the high performance LEDs used for fluorescence excitation compensate aging effects and temperature influences.

enviroFlu-HC is the new generation of immersion sensors for measurement of oil-in-water. The used measuring principle of UV fluorescence is much more sensitive than the conventionally used infrared scattering or absorption method. This allows to determine even the slightest traces of PAH's, for example in drinking water and cooling water condensates. Application areas include the petrochemical industry, leakage detection in cooling and wastewater streams as well as environmental monitoring.
