Operators can quickly finish parameter setup, spectrum viewing and data query without complicated training. 

### 2. Comprehensive Testing Functions It covers all mainstream lab spectroscopic measurement demands: - Photometric measurement - Quantitative concentration testing - Kinetics reaction monitoring - Full-spectrum scanning - DNA & protein concentration detection - Multi-wavelength simultaneous analysis Built-in large-capacity storage supports up to 1024M space to save test data and standard working curves, avoiding repeated calibration for frequent samples. 

### 3. Convenient Data Export & Connectivity Standard USB storage interface enables one-click data export to Excel for offline sorting, analysis and permanent archiving. Additional RS232 communication port supports stable connection with external PCs, realizing seamless laboratory digital management. 

### 4. Easy Maintenance & Replaceable Light Sources Adopts socket-type deuterium lamp and tungsten lamp. Users can swap light sources directly without complicated optical debugging, greatly lowering daily maintenance time and technical barriers. Imported light sources and silicon photodiode detectors guarantee long-term stable optical performance. 

### 5. Ultra-Large Sample Chamber & Expandable Accessories The spacious sample chamber accommodates cuvettes ranging from 5mm to 100mm, compatible with most standard sample containers. 

Multiple optional accessories are available to expand application scenarios: 

- Auto 8-cell holder for high-throughput testing 

- Film holder for solid film sample analysis 

- Peltier temperature control & sipper system for liquid flow measurement 

- 21 CFR compliant software for pharmaceutical regulated labs 

- Built-in thermal printer for instant report output
