  • Dissolved Oxygen Smart Sensor The Model 32 is a solid state DO sensor with built-in smarts which outputs to Modbus RTU through RS232 hardware. It is designed to be connected into existing hardware which accepts the Modbus RTU protocol. The Model 32 sensor is extrememly rugged and reliable, utilising solid state technology for DO measurement. I’m glad we got onto these, they’re great sensors, the M32 we have deployed is running like clockwork.”  Lia -  Hydrographer. VIC.
  • Mi415 Turbidity Meter

    Turbidity refers to the concentration of undissolved, suspended particles present in a liquid. Turbidity is a measure of the clarity of a sample, and for potable water applications, turbidity is a good indicator of water quality. Turbidity Measurement is achieved by analysing the amount of light refracted from suspended particles such as clay, silt and organic material. By measuring turbidity, by photometric or tube methods, it is possible to estimate suspended solids content.

    The Mi415 has two operating ranges; 0.00 to 50.00 FNU, and 50 to 1000 FNU that can accommodate the most turbid condition you may encounter. The Mi415 is supplied in a hard carrying case, complete with reagents.

  • Measures 4 parameters with 1 single probe. Mi805 offers you a combination of pH, Conductivity, total Dissolved solids and temperature measurements. You can select from a range of calibration buffers and also the temperature scale (°C or °F) can be selected. The multi-parameter probe MA851D/1, includes pH/EC/TDS and temperature, all in one rugged handle. Other features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients (ss) from 0.0 to 2.4% for greater consistency and reproducibility. The Stability Indicator prompts the user when the reading stabilizes. The Auto-Hold Function automatically freezes reading for later viewing. Large and Easy-to-Read display provides simultaneous readings of pH and Temperature or EC/TDS and temperature.

  • Mi306 Conductivity / TDS / NaCl / Temperature Professional Portable Meter

    Mi306 is a waterproof portable logging microprocessorbased Conductivity / TDS / NaCl / Temperature meter. The autoranging feature of the EC and TDS ranges automatically sets the meter to the scale with the highest possible resolution. The Auto Endpoint (HOLD) feature automatically freezes the display when a stable reading is reached.

    The measurements are automatically (ATC) or manually (MTC) compensated for temperature. The temperature coefficient value is user selectable. It is possible to disable the temperature compensation and measure the actual conductivity (NoTC). The Battery Error Preventing System (BEPS) switches the meter off when the batteries are too weak to support proper function. The meter can store measurements in memory by logging function for retrieval at a later time upon user request.

    Mi306 also allows data transfer to computer through the RS232 port. Double LCD displays, for simultaneous readings of the specific conductivity and temperature.

  • Plug & Play Compatability - Smart Sensors The InsiteIG Single Channel Analyser is a unique system that combines advanced electronics with solid-state, smart sensors. The analyser will accept any standard InsiteIG DO, SS, pH, or ORP sensor and automatically configures for the correct operation. The system allows for flexible and economical process monitoring and control. Fluorescence Dissolved Oxygen —Theory of operation A very specific energy wavelength is transmitted to a ruthenium compound immobilized in a sol-gel matrix. The ruthenium will absorb this energy, changing the outer electron’s energy level. The electron will then collapse back to its original energy state, emitting the energy as a photon with a different specific wavelength. This is called fluorescing. If the intensity of the transmitted wavelength is tightly controlled, the amount of fluorescing is both predictable and repeatable. If oxygen molecules are present the amount of fluorescing is reduced, referred to as fluorescence quenching. By measuring the amount of quenching it is possible to determine the amount of oxygen present. Download Brochure
