The mixer operates in a speed range from 50 to 1500 rpm, the maximum heating temperature of the working surface is 500 °C. The heating plate includes a base made of stainless steel and a working surface made of fire-resistant glass (glass ceramics). At temperatures above +550 °C, automatic overheating protection is triggered and turns off the heating. The device is equipped with an LCD screen to display set and actual temperatures, rotation speeds and additional animated icons. There is a timer for the specified operating time of the mixer; its maximum value is 990 minutes. There is a function for automatic detection of armature rotation failure. When the device detects an armature failure, the rotation stops. Then rotation resumes, but the speed is reduced by 10%, followed by restoration of the rotation speed to the user-specified parameters. A stall occurs if the armature becomes disengaged with the stirrer magnet and stops rotating. Disruption can occur for various reasons: the rotation speed is too high, the viscosity of the medium has changed during the mixing process, etc. When the power of the device is turned off, the set values of temperature, speed, timer time and the mode of detection (determination) of failure of armature rotation are stored in non-volatile memory. The armature rotation speed and heating temperature are set using two rotating knobs.

Primelab sand sauna, not included in delivery. Supplied separately. High-tech and productive magnetic stirrer with heating PL-HR-Steps, 20 liters, designed for laboratories of various profiles, including research and production purposes. The stirrer can mix at speeds up to 1500 rpm and heat up to +550 °C. The working platform is made of stainless steel, and the top covering is made of chemically resistant refractory glass (glass ceramics). The heated magnetic stirrer PL-HR-Steps has expanded functionality compared to the Basic modification. The Steps modification allows users to create and run their own special programs based on a graph of temperature and rotation speed versus time. The user can create a program by specifying a set of parameters for each step, including step duration, set temperature and rotation speed. The program subsystem provides flexible control of the heating and mixing process. The main functionality of the subsystem includes: • number of program steps from 1 to 5; • maximum step duration up to 990 minutes; • possibility of manual control control during program execution; • ability to run 1 program (heating/rotation). The PL-HR-Steps stirrer does not support "Gentle heating" modes. The user selects temperature, speed and time settings using two round knobs. The digital display shows the set and actual characteristics, as well as icons of the processes and functions being performed. The set parameters are saved in non-volatile memory. After heating is turned off, a warning about a hot platform is displayed on the screen. There is protection against overheating: at +550 °C the electric heating element automatically turns off. The stirrer is compatible with the PT1000 temperature sensor. The device is equipped with an armature failure monitoring function: if the rotation stops, the electric motor restarts.
