Magnetic Hotplate Stirrer (QXT-MH140)

Digital control with max. temperature at 340℃, speed up to 1500rpm.
Aluminum alloy work plate with flat plane provides fast heating performance, and strong compatibility with various heating containers and heating blocks.
High-resolution LCD display shows actual temperatures and speed.
PID controller ensures a precise and steady heating process.
External temperature control is possible by connecting the temperature sensor (PT 1000) with accuracy at ±0.2°C.
Brushless DC motor enables more powerful speed control.
Three heating modes for selected (fast heating, standard heating and stable heating).
Remote control function through RS232 interface provides PC control and data transmission.

Features
