FAQ
What are SafetyHeat™ and SmartHeat™?
They are OHAUS safety/control algorithms that help prevent overheating and overshoot. SafetyHeat™ monitors critical parameters, while SmartHeat™ optimizes temperature ramping and stability.
What is the maximum temperature and plate size?
The 7" x 7" ceramic plate reaches up to 550 °C with excellent stability for accurate heating.
Can I use an external temperature probe?
Yes. The unit supports Pt100 / Pt1000 probes (sold separately) and offers 3-point probe calibration for precise control.
Does it support data logging or remote control?
Yes. An onboard RS232 port enables remote control and data logging with compatible software.
What does the 20 L capacity refer to?
It indicates the approximate maximum stirring volume for aqueous solutions under typical conditions. Actual performance may vary with viscosity, vessel geometry, and bar selection.
