FAQ
How do SmartPresence™ and SmartLink™ improve safety?
They can automatically shut off the heater after a set timeout when no user is detected. SmartLink™ (via USB/Bluetooth accessory) extends detection range to enhance unattended shutoff.
What’s included in the box?
Power cord, 8" (20.3 cm) stainless steel RTD Pt1000 temperature probe, 1.5" (3.8 cm) PTFE-coated stir bar, and an in-use cover.
What heating and stirring performance can I expect?
Ambient +5 °C to 500 °C on the ceramic plate with precise stirring from 60–1600 rpm. Software-controlled ramp rate keeps magnetic coupling on viscous samples.
Is the chassis chemical-resistant and cool to the touch?
Yes. SmartHousing™ is chemical-resistant and designed to channel spills away from internal components while remaining cool to the touch.
Can I calibrate temperature?
Yes—temperature calibration supports up to 5 plate and 5 probe setpoints for high accuracy across common ranges.
