B&c italy offers a series of chemical controllers -ph565.2 ph controller, offering advantages of modern and reliable ph measurement and regulation for use in industrial plants, and is particularly for use in fermentation process. The input is from ph electrode and micro-transmitter and has two setpoints and output 0-20 or 4-20 ma. A mv 545.2 orp controller accepts input from probe or microtransmitter. The c565.2 conductivity controller undertakes measurement in ultrapure water and in solutions with very high ionic contents, featuring a scale selector and there are two independent and displayable on-off regulators with possibility of selecting min/max function and insert delay function for each setpoint. Od 565.2 dissolved oxygen controller takes input either from polarigraph cell or from microtransmitter and has automated temperature compensation. Cd 565.2 dissolved co2 controller is suitable for fermentation process. Together with co2 sensor it provides a digital readout of co2 concentration in aqueous solution with 3 1/2 digit readout and two setpoints. Zero and slope corrections are available on front panel. Af 511.2 antifoam indicator is suitable for use in fermentation plants as it measures the conductivity of foam. The measurement value is displayed by means of led bar graph. All these models are available in din mounting, rail mounting, transmitters, etc.
