<p>This invention relates to an improved probe designed in particular but not exclusively for measuring the concentration of live biomass. The probe has an insulating body portion arranged to carry a first and second electrode where the probe has a longitudinal axis and the first and second electrodes extend in this longitudinal axis. The body portion has a cross-sectional area perpendicular to the longitudinal axis defined by a major axis and minor axis, wherein the length of the body portion in the major axis is greater than the length of the body portion in the minor axis. The first and second electrodes are positioned on either side of the major axis. This reduces the effect of impedance between the electrode and the liquid through increasing the effective distance between the electrodes.</p> |
