Aber Instruments Ltd launched  their new range of Models 720 and 710 Yeast Monitors at Drinktec Interbrau and the first of these systems were despatched to major brewers in the UK, Belgium and Poland at the end of 2005.  The new range has incorporated the latest developments in radio-frequency impedance that allows a higher specification instrument to be manufactured at a lower cost. The Yeast Monitor Model 720 has an integral multiplexer, allowing the unit to be expanded up to 4 channels and it is completely contained within a stainless steel IP65 enclosure. The Model 720 has the flexible option of monitoring from the same instrument both yeast slurries and the relatively low cell concentrations found in propagators or krausening operations. The Model 710 is a budget instrument, ideal for a dedicated yeast pitching or cropping applications requiring only one probe. Communication options include separate 4-20mA outputs for live cell concentration and conductivity and options for Profibus and other fieldbus communications to the PLC.

The 720/710 range incorporates a new "auto-calibration" facility that allows each yeast strain to be calibrated accurately prior to installation on-line.
