The 4 stirringpoints are arranged in a circle around a lampmaking it easier to observe the flocculationprocess.State-of-the-art technology ensures maximumoperating convenience and makes the unit maintenance-free.The main features of thelaboratory jar testers are the continuouslyvariable stirring speed, the digital display of stirringrpm, the timer function, the illuminated backpanel, and the height adjustment option for thestirring blades during operation.ET 730 requires 1000 ml beakers of low form.ET 740 and ET 750 require 1500 ml beakers of lowor high form. The beakers are not included.Technical data ET 750 ( laboratory)Stirring placesStirring speed controlResolutionTimerPower supplyWeightDimensions (mm)EC-conformitysix10 - 300 revolutionsper minute1 revolution1 - 999 minutes or0 - 99 hours(continuous)100 – 240 V, 50 - 60 Hzapprox. 17 kg935 L x 347 W x 260 HCEOrder code 2 41 91 60Technical data ET 730(portable/field)Stirring places fourStirring speed control 20 - 40 - 50 - 100 - 120revolutions per minuteTimer1 - 30 minutes(continuous)Power supply 100 – 240 V, 50 - 60 HzWeightapprox. 4.8 kgDimensions (mm) 250 L x 320 W x 250 HEC-conformity CEOrder code 2 41 91 50Flocculation & SedimentationAccessoriesMeasuring beaker, glass, 41 91 65low form, 1000 mlpackaging unit 10 piecesMeasuring beaker, glass, 41 91 66low form, 1000 mlpackaging unit 6 piecesGeneral Catalogue November 2010129
