OHAUS Guardian 7000 Hotplate Stirrers are designed with outstanding safety features and superior heating and mixing performance. The SmartHousing™ is chemical resistant with an innovative, easy-to-clean design that channels spills away from internal components and the angled glass control panel. The bright LCD display includes intuitive icons, temperature, speed and time settings - all designed to monitor performance from across the lab.

Features
  • SmartPresence™ and SmartLink™ Technologies Ensure Supervised Operation— Protect your lab with patented SmartPresence™ and SmartLink™ technologies. These exclusive features automatically shut off the heater if no one is detected after a user set “time out” period has passed.
  • SafetyHeat™ System Protects the Lab— An industry-leading, early-detection system that uses two independent safety controls to continuously monitor the electronics and shut off heating before an over-temperature condition occurs.
  • Powerful, Consistent Stirring Performance— Precise stirring from 60 to 1600 rpm is made possible by the design of a powerful motor, strong magnet and software controlled ramp rate, ensuring secure magnetic coupling for viscous applications.
  • Customized Performance for Precise Applications— SmartHeat™ allows you to set the maximum temperature of the unit and SmartRate™ enables fast or slow temperature and speed ramp rates. The programming feature allows storage of 5 multi-step programs.
