Ohaus® Guardian™ 7000 Hotplate Stirrers

The Ohaus® Guardian™ 7000 is a durable Hotplate Stirrer with superior safety features and intelligent 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.

Unique Features:

  • SmartPresence™ and SmartLink™ technologies ensure supervised pperation: 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.
