7 Inch LCD Digital Magnetic Hotplate Stirrer 20L Aluminum Cover MS7-H380-E
LCD Digital Magnetic Hotplate Stirrer
Features
- Corrosion-resistant Ceramic Coated Aluminum Hot Plate - 178×178mm large heating surface with ceramic coating, excellent resistance to acid, alkali & organic solvents, smooth surface for easy cleaning, uniform & fast heat transfer.
- Spill-proof Guided Platform Design - Sloped drainage structure diverts spilled liquid outward, prevents liquid penetration into internal circuit boards to extend machine service life.
- High Volume Mixing Capacity - Max stirring volume up to 20L water, max heating temperature 380℃, adjustable stirring speed 0-1500rpm, ideal for large-volume & high-temperature reactions.
- Clear LCD Digital Display - Simultaneously shows stirring speed, temperature & timer; two independent control knobs for separate heat & stir adjustment, user-friendly operation.
- Compatible with PT1000 External Temperature Sensor - External PT1000 probe immerses directly into samples to monitor real liquid temperature, eliminates temperature deviation between plate & solution.
- Multi-layer Safety Protection - Built-in dry-burn prevention, overcurrent, earth fault & overtemperature protection; auto power-off under abnormal conditions to avoid lab hazards.
- Residual Heat Warning Function - Flashing "HOT" alert on screen when plate temperature exceeds 50℃; warning remains active even after power cut to prevent scald injuries.
