About this item Audit Tracking & Security: provides full audit tracking with user-level permission management. Super administrators can manage all accounts, track operations, lock/unlock users, and export tamper-proof PDF/Excel data via USB. All actions are fully recorded User Management: supports hierarchical user management. Super administrators assign permissions, while administrators can create multiple users. Each user has a unique login with enable/disable controls for flexible personnel management Data Retrieval: powerful data search function allows users to quickly locate required records within large datasets, improving efficiency Real-Time Graph Display: graphs are displayed in real time during testing for easier analysis. Historical graphs and recorded images can also be replayed Expandable Memory: system memory can be expanded to meet growing data storage needs Easy Software Upgrade: supports automatic software upgrades via USB, eliminating the need to return the device to the factory Technical Indicators Model GM30 GM50 Temperature range room temperature - 350°C Room temperature-400°C Detection mode semi-automatic/manual Manual Processing capacity 4 per batch (up to four samples can be processed simultaneously) Judgment ability visual inspection via video Temperature resolution 0.1°C Heating rate 0.1°C - 20°C (200 levels, infinitely adjustable) Temperature control mode precise PID temperature control, fully enclosed furnace design Heating method conductive liquid heating or electric block air heating (optional) Temperature rise resolution 0.1°C Temperature rise rate 0.1°C/min - 20°C/min Accuracy ±0.3°C (200°C) ±2°C (200°C) Repeatability at a temperature rise rate of 0.1°C/min, the melting point repeatability is ±0.1°C Calibration function Yes Exploration mode Yes Video function photographing and filming Video playback available/with time watermark High-definition camera observes the melting state of the sample Magnification =10 User management more than 30, with three-level classification.
