Bringing Effortless Accuracy to Your Lab 為您的實驗室帶來輕鬆精準的檢測分析

Built on the trusted legacy of the DR3900, the DR4900 Spectrophotometer increases analytical reliability and strengthens your laboratory’s operational performance. Engineered for routine and high‑throughput water analysis, the instrument combines stable optics, automated verification functions, and streamlined workflows to deliver consistent, traceable results across a wide range of parameters.
DR4900 分光光度計傳承 DR3900 的可靠技術，提升分析可靠度，強化實驗室的運作效率。專門為常規和檢測數量多的水質分析而設計，整合穩定的光學系統、自動化驗證功能以及簡化的工作流程，讓您檢測超過百種以上的水質參數都能獲得一致並且可追溯的分析數據結果。

Accurate, reproducible data is fundamental for laboratory oversight. The DR4900 reduces sources of analytical variability by integrating diagnostic controls, guided workflows, and an interface designed to standardize testing steps. The result is fewer repeat analyses, reduced operator‑dependent variation, and better confidence in day‑to‑day results.
準確、可重複的分析數據是實驗室控管的基礎。 DR4900 透過整合診斷控制、引導式工作流程和標準化測試步驟的使用者介面，以減少分析變異，進而減少重複分析次數，降低操作人員差異，並提高對每次分析結果的信心。

Technical Innovations That Protect Data Integrity 創新技術帶來保護資料完整性

10-inch High‑Resolution Touchscreen 10 吋高解析度觸控式螢幕
The large, full‑color display enables rapid navigation of analytical steps, clear visualization of spectral data, and fast review of sample information. The modern UI is optimized for multi‑operator labs, reducing training time and minimizing navigation errors.
大尺寸彩色顯示螢幕顯示分析步驟的快速導航、光譜資料的清晰視覺化，以及樣品資訊的快速檢視。現代化的使用者介面針對多操作人員的實驗室進行最佳化，可縮短培訓時間並大幅降低錯誤可能性

Integrated Turbidity Diagnostics 整合濁度診斷
Optical monitoring verifies whether sample turbidity may interfere with TNTplus vial measurements. The system alerts the operator when filtration or additional sample preparation is recommended, helping maintain result accuracy in samples with suspended solids.
光學監測功能可驗證樣品濁度是否會干擾 TNTplus 樣品瓶的測量。當需要進行過濾或額外的樣品製備時，分析儀系統會發出警示，以協助維持含懸浮固體水樣的測量結果準確度。

Temperature Monitoring for Vial Tests 樣品瓶測試溫度監測功能
An integrated temperature sensor evaluates vial temperature prior to measurement. This helps ensure that exothermic reactions or insufficient equilibration times do not impact analytical output, particularly important for temperature‑sensitive colorimetric methods.
內建溫度感測器，可在測量前評估樣品瓶溫度。以協助確保放熱反應或平衡時間不足不會影響分析結果，這對於溫度敏感的比色法尤其重要。

With more than 250 pre‑programmed Hach methods, including a broad range of regulatory‑relevant parameters, the DR4900 supports standardized workflows and consistent method execution. Its robust optical design and built‑in diagnostics help maintain instrument performance over time, giving you greater oversight and control over daily testing operations.
