Magnetic stirring hotplates MR Hei-Standard / Hei-Tec / Hei-End
Safe Heating and Mixing
-The extended heating capacity of 800 W reduces heat-up times by 35 % compared to other units at 600 W
-The chemically resistant KeraDisk® hot plate allows for immediate heat transfer resulting in quick heat-up times
-In case the heating function fails, stirring will not be discontinued to prevent bumping
-A separate on/off button for heating prevents unintentional heat-up - the button is illuminated for visual control
-Damage to the stirrer is categorically ruled out even if exposed to highest temperatures - all models come with a fire-resistant aluminum die-cast housing
-In case of a short-circuit, a damage or removal of the temperature sensor from the media, the unit powers off completely
-The temperature sensor consists of two independent safety circuits which switches off heating in case of any overtemperature situation
-Hermetically-sealed housing protects all mechanical and electronic components from aggressive environments
-The average operational lifespan of 10 years is backed by a 3 year warranty and makes your purchase a truly worthwhile investment
-Speed is adjustable from 30rpm till 1400rpm at an accuracy of ±1% for gentle mixing
-Safety circuits avoid an overheat situation of your hotplate. If the temperature overshoots, heating will be powered off immediately
-The strong magnetic field allows for stirring of even higher viscosity media or stirring a volume of 20L of water with ease
-With a heating power of 800 W the hotplate reaches a maximum temperature of 300 °C in a significantly reduced time period

MR Hei-Standard - Model for standard applications without temperature sensor
-For your protection an independent safety circuit will switch off heating if the hotplate temperature exceeds 25°C over set temperature
-A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button is illuminated for visual control
-Analog knobs allow for convenient speed setting from 100rpm to 1400rpm at an accuracy of 2% and temperature setting up to 300°C
-With connection for temperature sensor PT1000 (optional)

MR Hei-Tec - Model for higher requirements with temperature sensor
-This units features a digital display and allows for easy setting and monitoring of values by the illuminated readout
-For your protection an independent safety circuit will switch off heating if hotplate temperature exceeds 25°C over set temperature
-Digital speed setting from 100rpm to 1400rpm at an accuracy of 2% and temperature setting up to 300°C
-Upgrade this magnetic stirrer with the optional Pt 1000 temperature sensor for precise temperature control, overshoot protection and reproducible results
-A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button is illuminated for visual control

MR Hei-End - Model for highest safety
-A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button is illuminated for visual control
-An independent safety circuit switches off heating at an operator-programmed temperature value above your set temperature
-An additional operational safety step is required to change parameters which prevents unwanted changes to the actual setting
-The digital display allows for easy setting and monitoring of values on the illuminated readout. Speed setting from 30rpm to 1400rpm at an accuracy of 1% and temperature setting up to 300°C
-Hotplate residual heat indicator in the digital display illuminates when unit is turned off and hotplate temperature is above 50°C to prevent accidental operator injury
-To protect your sample from overheating a safety circuit switches off heating if the temperature sensor is not immersed in your media vessel
-Upgrade this magnetic stirrer with the optional Pt 1000 temperature sensor for precise temperature control, overshoot protection and reproducible results
