Description
7x7 Digital Magnetic Hotplate Stirrer | USA Lab
The USA Lab 7-H550-PRO is a technically advanced lab hotplate stirrer featuring independent back-lit LCDs for heat and stir functions, PID temperature control to ±1°C, and a durable brushless DC motor. TÜV certified for safety, it delivers precise heating and vigorous stirring for chemical synthesis, analytical workflows, and biopharma labs.
With a 7"×7" glass-ceramic plate for superior chemical resistance and heat transfer, external PT1000 sensor support (accuracy ±0.2°C), and digital speed regulation up to 1,500 rpm, the 7-H550-PRO pairs control with reliability in daily use.
Integrated safety includes over-temperature protection, a flashing “HOT” warning above 50°C (even when powered off), and a stable chassis for confident operation.
7" Glass-Ceramic Plate 550°C Max Temp Up to 1,500 rpm PID & LCD Control PT1000 External Sensor TÜV Certified
Performance: Brushless DC motor delivers smooth torque and up to 1,500 rpm for robust vortex and dispersion.
Precision: PID loop with ±1°C control (PT1000 to ±0.2°C) and independent LCDs for heat/stir readout.
Safety: 550°C max plate temp with over-temp protection and persistent “HOT” 50°C warning indicator.
