Cost-effective laboratory stirrer designed for simple stirring tasks for quantities up to 20 l (H2O). Automatic speed adjustment in the range between 50 and 2200 min-1 via microprocessor-controlled technology. Safety circuits ensure automatic cut-off in an anti-stall or overload situation. Actual and set speed are constantly monitored ensuring no undesired speed variations, even if the sample viscosity changes.Brushless, maintenance-free motorDigital speed displayDisplay for speed or torque changeableInfinitely adjustable speedOverload protectionNon-slippery matSlim casingQuiet operationError code displayRS232 portStand:Stainless steel stand incl. boss head, dimension (W x D x H): 200 x 310 x 780 mm, non-slippery matStirrer:4-blade propeller stirrer, stainless steel, shaft length 400 mm, stirrer diameter 50 mmScope of supply: Overhead stirrer LLG-uniSTIRRER OH2, stand, non-slippery mat and 4-blade-propeller stirrerSpecificationsMax. stirring quantity (H2O):20 lSpeed range:50 ... 2.200 min-1Max. viscosity:10,000 mPasMotor rating input/output:60/50 WSpeed display accuracy:± 3 min-1Max. torque at stirring shaft:40 NcmDisplay:LCDChuck range:0.5 ... 10 mmDimensions (W x D x H):83 x 186 x 220 mmPower supply:110 ... 240 V, 50/60 HzIP code:IP 21Warranty:3 years

Universal laboratory stirrer designed for simple stirring tasks for quantities up to 25l (H2O). It automatically adjusts the speed through microprocessor controlled technology within the speed range of 0/30 to 2000rpm. Safety circuits installed ensures automatic cut-off in an anti-stall or overload conditions. Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in viscosities of the sample.Digital speed displayInfinitely adjustable speedPush-through agitator shaftsOverload protectionShort-term overload operationSpecificationsStirring quantity max.
