OHAUS Guardian 7000 Hot Plate Stirrers

OHAUS Guardian 7000 Hot Plate 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. Precise stirring from 60 to 1600 RPM is made possible by the design of a powerful motor, strong magnet, and a software-controlled ramp rate, ensuring secure magnetic coupling for viscous applications.

SmartPresence and SmartLink Technologies ensure supervised operation. Protect the lab with the patented SmartPresence and SmartLink technologies. These exclusive features automatically shut off the heater if no one is detected after a suer set “time out” period has passed or the Bluetooth® link between a paired mobile device is broken.

SafetyHeat System is an industry-leading early detection system that ususes two independent safety controls to continuously monitor the electronics and shut off heating before an overtemperature condition occurs.

SmartHeat allows the user to set the maximum temperature of the unit and SmartRate enables fast of slow temperature and speed ramp rates. The programming features allows storage of five multi-step programs.
