For stirring; heating and controlling. As well as the ability for rapid and temperature-controlled heating; many applications also require liquids to be stirred. You can use the SLR hotplate / stirrer to provide gentle or vigorous liquid stirring and; if required; gradual heating or cooling. All functions are displayed on the clear LCD panel and can be monitored. The stirrer and heater are individually controlled via manual control knobs. The stirrer can be set from 100rpm to 1100rpm x 10rpm increments. True running is achieved even at the lower end of the rpm range. Heating can also be adjusted over 24 steps attaining an average of 0.9kW at the top of the range. It is possible to regulate temperatures between 25°C and 200°C with variations of between ±2°C and ±5°C using the Pt1000 temperature sensor; depending on the liquid volume; heat capacity and ambient temperature conditions. 230 V.
