  • Hanna Multi Parameter – HI98194

    pH/ORP/EC/TDS/Salinity/DO/Pressure Meter

    The HI98194 is a waterproof portable logging multiparameter meter that monitors up to 12 different water quality parameters including 6 measured and 6 calculated. The microprocessor based multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, and temperature. The probe transmits readings digitally to the meter, where data points can be displayed and logged. The HI98194 is supplied with all necessary accessories and packaged in a durable carrying case

  • Optical Dissolved Oxygen Meter – HI98198

    The HI98198 Optical Dissolved Oxygen Meter makes measuring the concentration of dissolved oxygen hassle-free. Optical DO technology doesn’t require a minimum flow rate, so there is less drift in your readings. Perfect for the field or for the laboratory, the Quick Connect probe requires no membranes, no filling solution, and no warm-up time so you can measure without hesitation. Your meter comes complete in a rugged, custom carrying case for easy transportation.

  • RWT G95A – Galvanic Dissolved Oxygen Sensor


    The Australian made RWT G95A is the next generation in Dissolved Oxygen measurement. We have taken a sensor that was already good and made it better.

  • RWT O95A – Fluorescence Dissolved Oxygen Sensors


    The Australian made RWT O95A is the next generation in Fluorescence Dissolved Oxygen measurement. We have taken a sensor that was already good and made it better.

  • WTW-2020 (IQ Sensor Net)

    Improve operational efficiency with continuous data. With an easily scalable solution, the 2020 XT allows for the connection of up to 20 sensors. Add sensors at any time and at any location or change them out with ease. This completely modular plug-and-play system allows you to monitor and control the water quality in your wastewater facility continuously and accurately.

  • WTW-282/284 (IQ SensorNet)

    The new controller DIQ/S 282/284 is available as 2- (DIQ/S 282) or 4-channel-version (DIQ/S 284). Besides the reagent-free measurement of COD, all other parameters needed for a wastewater treatment plant can be measured. By the combination of multi-parameter sensors, up to 20 parameters can be measured and displayed simultaneously.


    YSI-PRO ODO Portable Optical Dissolved Oxygen Meter – Expanded DO range of 0-500% with a response time of T90 in approximately 25 seconds

  • MXD 73/75

    MXD 73/75 Surface or Panel  Online Galvanic Dissolved Oxygen Analyser – Range 0 – 99.9 PPM and % Saturation 0 – 99.9%.

  • WTW Optical FDO® 700 IQ Sensor

    Optical working D.O. sensor for the measuring and control of oxygen concentration in the biological cleaning process of wastewater plants

  • BGD17 – Single Input Controller – Dissolved Oxygen

    The BGD17 is a microprocessor controlled instrument range offering individual controllers for the measurement parameters Electrodeless (Inductive) and Contact Conductivity, Dissolved Oxygen Measurement. To achieve this the instrument utilises a clear multifunction LCD to display the primary reading and temperature, show operational status and to provide an intuitive user interface.
