OHAUS has introduced the Guardian 7000 Hotplate Stirrers that deliver excellent heating and mixing performance, and include exceptional security features.
The SmartHousing™ is resistant to chemicals and features a novel, easy-to-clean design that guides any spills away from the angled glass control panel and internal components.
The bright LCD display features temperature, time, and speed settings, as well as intuitive icons — all designed to track the performance across the laboratories.

Unique Features
-
SmartLink™ and SmartPresence™ Technologies Ensure Supervised Operation
Users can safeguard their laboratories with patented SmartLink™ and SmartPresence™ methods. These special features turn off the heater automatically if no one is detected once a user set “time out” period has passed.
-
SafetyHeat™ System Protects the Laboratory
An industry-leading early detection system utilizes two separate safety controls to constantly track the electronics and turn off the heating before an over-temperature condition.
-
Powerful and Consistent Stirring Performance
Accurate stirring from 60 to 1600 rpm can be achieved due to the design of a powerful magnet, strong motor, and a software-controlled ramp rate. All these guarantee safe magnetic coupling for viscous applications.
-
Customized Performance for Precise Applications
With the SmartHeat™ technology, users can set the unit to a maximum temperature, while the SmartRate™ allows slow or fast temperature and rapid ramp rates. The programming feature also enables users to store up to five multi-step programs.
GUARDIAN™ 7000 Hotplate Stirrers
SmartHeat™
The SmartHeat™ safely regulates the highest temperature by avoiding the overheating of sensitive samples.
SmartLink™
In case the Bluetooth® link is broken, the heating function will turn off safely.
SmartRate™
The SmartRate™ allows users to choose either slow or fast temperature and speed ramp rates for accurate control of samples.
SmartHousing™
The SmartHousing™ is resistant to chemicals and remains cool to touch.
SmartPresence™
Special proximity sensor technology identifies nearby users and safely switches off hotplate if none are detected.
SafetyHeat™
The industry-leading internal protection system ensures security in heating applications with dual monitoring of system health.
