MS-H340-S4 Digital 4-Channel Hot Plate Magnetic Stirrer
Product Introduction
The MS-H340-S4 Digital Hot Plate Magnetic Stirrer is a high-performance four-channel laboratory magnetic stirrer with heating function, designed for simultaneous mixing and temperature-controlled heating of multiple samples.
Equipped with four independent heating plates, individual temperature and speed control, PID intelligent temperature regulation, and brushless DC motors, the MS-H340-S4 provides accurate, stable, and safe operation for demanding laboratory applications.
With a maximum heating temperature of 340°C, stirring speed up to 1500 rpm, and support for external PT1000 temperature sensors, this multi-position magnetic stirrer is widely used in chemistry, biology, pharmaceutical research, material science, and industrial laboratories.

Key Features & Advantages

● Four heating positions operate independently.
● Each channel has separate temperature and speed control.
● Allows simultaneous processing of multiple samples.
● Improves laboratory efficiency and experimental throughput.
2. Precise PID Temperature Control
● Advanced PID control technology provides real-time heating adjustment.
● Maximum temperature reaches 340°C.
● Temperature display accuracy: ±0.1°C.
● External PT1000 sensor enables sample temperature accuracy up to ±0.2°C.
3. Powerful Magnetic Stirring Performance
● Maximum stirring speed: 1500 rpm.
● Single position stirring capacity up to 10L (H₂O).
● Supports magnetic stir bars up to 40 mm.
4. Safe Brushless Motor Design
● Explosion-resistant DC brushless motor.
● No sparks, no maintenance requirements.
● Provides long service life and improved laboratory safety.
5. Advanced Safety Protection
● Residual heat warning when plate temperature exceeds 50°C after heating stops.
● Independent over-temperature protection circuit.
● Automatically stops heating when temperature exceeds 420°C.
6. Durable Chemical-Resistant Structure
● Stainless steel ceramic-coated heating plates.
● Excellent corrosion resistance and temperature uniformity.
● Fully enclosed aluminum alloy housing improves heat dissipation.
● Powder-coated surface provides chemical resistance.

Working Principle
The MS-H340-S4 Digital Hot Plate Magnetic Stirrer combines electric heating technology with magnetic stirring principles.
The heating plate converts electrical energy into controlled thermal energy, while the magnetic drive system generates a rotating magnetic field that drives the stir bar inside the container.
The built-in PID temperature control system continuously monitors and adjusts heating power according to the set temperature. When connected with a PT1000 external temperature sensor, the system directly measures sample temperature and automatically compensates heating changes to achieve precise temperature control.
The four independent control units allow each sample position to operate separately for flexible multi-sample experiments.
