Sensor that makes full use of Rotary Cell Length Modulation (Patent pending)
Zero drift correction is perfomed in every cycle of measurement. This correction can eliminate the effect of any interference on cells.
Cell length modulation provides readings from multiple measurements, making available results from various cell lengths. This allows the single device to make measurements on a large range of concentrations from as low as 0 to 0.1 Abs, up to 0 to 5.0 Abs.
