  • Dissolved Carbon Dioxide Meter/CO2 Tester-CO230

    Dissolved Carbon Dioxide Meter/CO2 Tester-CO230

    Dissolved carbon dioxide (CO2) is a well‐known critical parameter in bioprocesses due to its significant impact on cell metabolism and on product quality attributes. Processes run at small‐scale faces many challenges due to limited options for modular sensors for online monitoring and control. Traditional sensors are bulky, costly, and invasive in nature and do not fit in small‐scale systems. In this study, we present the implementation of a novel, rate‐based technique for on-field measurement of CO2 in bioprocesses. The gas inside the probe was then allowed to recirculate through gas‐impermeable tubing to a CO230 meter.
  • Conductivity/TDS/Salinity Meter/Tester-CON30

    Conductivity/TDS/Salinity Meter/Tester-CON30

    The CON30 is an economically priced, reliable EC/TDS/Salinity meter that is ideal for testing applications such as hydroponics & gardening, pools & spas, aquariums & reef tanks, water ionizers, drinking water and more.
  • Dissolved Hydrogen Meter-DH30

    Dissolved Hydrogen Meter-DH30

    DH30 is designed based on ASTM Standard Test method. The precondition is to measure the concentration of dissolved hydrogen at one atmosphere for pure dissolved hydrogen water. The method is to convert the solution potential into the concentration of dissolved hydrogen at 25 degrees Celsius. The measurement upper limit is around 1.6 ppm. This method is the most convenient and fast method, but it is easy to be interfered by other reducing substances in the solution.
    Application: Pure dissolved hydrogen water concentration measurement.
