Powerful stirring performance with strong vortex, ideal for a wide range of laboratory applications.
In the laboratory equipment market, low-cost competitors often suffer from issues such as inaccurate analog knobs, short-lived brushed motors, easily corroded heating plates, and lack of over-temperature protection. The Hengnuo MS-H Series fully upgrades to solve these industry points:
1. 【Core Advantage】 Brushless DC Motor vs. Brushed Motor
Competitors often use brushed carbon motors, which wear out quickly and generate sparks. Hengnuo adopts a brushless DC motor – maintenance-free, explosion-proof, quiet, and extremely durable. It can be safely used even in flammable or explosive reagent environments.
2. 【Precise Temperature Control】 Digital Display + External PT1000 Sensor
Competitors’ analog knobs offer vague control. Hengnuo features a high-resolution LCD/LED display with accuracy down to ±0.1°C. By connecting an external PT1000 temperature sensor, the liquid temperature can be controlled with an accuracy of ±0.2°C (see Image 3). This is a standard feature for high-end experiments.
3. 【Safety First】 Multiple Safety Protections
Many ordinary hotplates lack overheat protection, posing fire risks. Hengnuo includes built-in safety circuit over-temperature protection (up to 420°C). When the plate temperature exceeds 50°C, the "HOT" warning light flashes – even when the unit is turned off – to prevent burns.
4. 【Durable Material】 Ceramic-Coated Work Plate
Traditional aluminum plates are easily corroded by acids and alkalis. Hengnuo uses stainless steel/aluminum with ceramic coating for excellent chemical resistance and long service life.

Q1: What is the difference between MS-H-Pro+ and MS-H-S?
A: The MS-H-Pro+ features LCD digital control, with a more intuitive display and support for an external PT1000 sensor for precise temperature control. The MS-H-S uses analog knob control – more affordable and suitable for basic heating and stirring where high precision is not required.
Q2: Can your stirrer handle viscous liquids?
A: Yes. Our motor is a brushless DC motor with high torque, capable of stirring up to 20L (water). For viscous liquids (such as glycerol or polymers), we recommend reducing the speed or using a longer stir bar.
Q3: What if the work plate gets scratched?
A: Hengnuo’s work plates feature a ceramic coating. Although scratch-resistant and durable, avoid using hard metal tools on the surface. Minor scratches do not affect heating performance or chemical resistance, and the plate can continue to be used.
