  • Nikkiso

    The model 7118 dissolved oxygen analyzer is designed for online measurement of dissolved oxygen concentration in the condensate and feed water of thermal or nuclear power plants. Membrane electrodes are used to measure dissolved oxygen. This allows the analyzer to be used in a closed-loop system without contaminating the samples. Three measurement ranges are available: 0.0?50.0µg/L (resolution of 0.1 µg/L between 20.0 and 50.0 µg/L), 0?250µg/L (resolution of 1 µg/L between 100 and 250.0 µg/L), and 0?2000µg/L (resolution of 0.1 µg/L between 500 and 2000 µg/L).

  • pHionics

    pHionics offers dissolved oxygen sensors and transmitters for water quality monitoring and control. Their STs6020C is an isolated series 2-wire, 4-20 ma dissolved oxygen transmitter. The  STs6020TC is also an isolated 2-wire, 4-20 ma dissolved oxygen transmitter but comes with an additional temperature output channel. The STs6020B has 0.00 - 2.00 vdc output and is self-powered with internal AA battery. The STs6020V also has 0.00 - 2.00 vdc output but is powered by an external source (such as a 12 volt battery).

  • Sensorex

    The Sensorex line of dissolved oxygen probes are galvanic sensors with large reservoirs of electrolyte. They are available with mV or 4-20mA outputs. Their Lab dissolved oxygen probes are designed for use with galvanic dissolved oxygen meters, transmitters and controllers. Their Process dissolved oxygen probes feature a large volume electrolyte reservoir for long term continuous deployments.

  • Geo Scientific

    Geo Scientific offers dissolved oxygen sensors that produce a millivolt output proportional to the oxygen present in the medium in which it is placed. Other products include submersible water quality transmitters that utilize integrated preamps and an isolated 2-wire, 4-20 mA transmitter.

  • Waltron

    The Waltron Aqualyzer 9061 and 9061C Dissolved Oxygen Analyzers are microprocessor-based instrumentation packages designed for use in measuring low and high concentrations of dissolved oxygen. Both employ galvanic technology and offer ranges of 0.01ppb-20ppm. The Waltron Aqualyzer 9062 Dissolved Oxygen Analyzer offers a combined wet section and transmitter.

  • Endress Hauser

    Endress & Hauser offer digital amperometric dissolved oxygen sensors with measuring ranges of 0,001 up to 100mg/l. Applications include food, pharma, power, chemistry, water and waste water. Brand names offered include Memosens and Oxymax. Dissolved oxygen transmitters (in two and four wire configurations) and assemblies are also available.

  • Vernier

    The Vernier dissolved oxygen probe has a range of 0 to 14 mg/L (ppm). It has built-in temperature compensation, so you can do your calibrations in the lab and then make measurements outdoors without the need for recalibration. Accessories available include DO filling solution, calibration solution, polishing strips, water depth samplers, membranes for DO sensors, and electrode support.

  • Hach

    The Hach 9182 Dissolved Oxygen Analyzer provides a detection range of 0-2000 µg/L (ppb). Calibration requires less than fifteen minutes and membranes come pre-mounted and ready for use. The consumables kit (membranes and electrolyte) supplied with each analyzer lasts for up to two years of operation. Analog outputs include instrument measurement and temperature, and four relays provide high/low limits, system error notification and timer.

  • Mocon

    MOCON's 02 analyzer uses optical fluorescence technology to measure dissolved oxygen, permeation, headspace, leak detection, non-destructive shelf-life analysis, reads values in 0.5 seconds, has a range from 0.001 to 30% 02, and complies with ASTM F2714-08.

  • Alpha Omega Instruments

  • Forbes Marshall

    The Forbes Marshall dissolved oxygen analyzer features a measurement range of 0 to 2000 ppb, membranes pre-mounted on retaining caps to suppress delicate membrane handling, zero and slope two-point calibration, processes ppb valuews in less than 15 minutes, has two smart analog outputs and four relays (for high/low limits, system error and timer).

  • RMS
