Durable Hotplate Stirrers with Superior Safety Features and Intelligent Performance

Offering the next generation of exclusive OHAUS SMART technology, the flagship Guardian 7000 Series ensures supervised lab operation with SmartPresence™ and SmartLink™.

Protect Your Lab with Patented SmartPresence™

SmartPresence™ - an exclusive IR-based proximity sensor recognizes a user nearby and when none is detected, safely turns off the heating function, ensuring supervised operations in your lab.

The Guardian 7000 features SmartLink™ providing long-range lab supervision by installing the OHAUS Bluetooth® dongle accessory into the USB port and pairing to a mobile device. If the Bluetooth® link is broken, the heating function safely shuts off.

Guardian Hotplate Stirrers are designed for durability and reliability with exclusive SmartHousingä that is consistently safe to use at high temperature settings, and include a chemical-resistant control panel that remains cool to the touch, with an easy-to-clean design that channels away spills from the internal components.

The Guardian 7000 Series features SafetyHeat™ - our industry-leading internal protection system that assures safety in heating applications with dual-monitoring of system health and SmartHeatä which allows lab users to set the maximum temperature of the hotplate stirrer, preventing overheating of sensitive samples -- keeping the user and samples safe.

For precise sample control with the Guardian 7000, use the included temperature probe and enable SmartRate™ to select fast or slow temperature and speed ramp rates.

The Guardian 7000 features an easy to read LCD display that includes large temperature, time and speed settings, intuitive icons and a prominent hot top light.
