The AC 500 - Automatic Colorimeter is a high-performance spectral colorimeter for measuring the color of clear and transparent liquids across over 25 international color scales, including ASTM, ISO, DIN, USP, and EP. Equipped with automatic wavelength calibration, automatic cell recognition, and advanced data storage, it provides precise, reproducible, and network-ready color measurement for laboratory and industrial quality control applications.
The AC 500 Automatic Colorimeter is a state-of-the-art laboratory instrument designed for accurate color measurement, transmission, extinction, and wavelength scanning of clear and transparent liquids. Capable of covering over 25 color scales, the instrument supports global standards such as ASTM D1209, D156, D1544, ISO 6271, ISO 4630, USP, EP, CP, and DIN 6162, making it suitable for petroleum products, lubricants, oils, fats, beverages, and pharmaceutical liquids.
The device features a 7-inch high-resolution TFT color touch screen, offering an intuitive, multilingual interface (16 languages) for easy navigation. Automatic functions include cell recognition, wavelength calibration, and measurement procedures, reducing manual intervention and enhancing reproducibility.
With extensive data storage capabilities — 100 color references, 1000 photometric values, 20 time scans, 20 wavelength scans, and 3000 color readings — and Ethernet/USB connectivity, results can be directly integrated into LIMS or laboratory networks for seamless reporting and compliance tracking.
The AC 500’s optical system (0°/180° rectilinear) and photometric accuracy (0.005 Abs at 0–0.5 Abs, 1% at 0.5–2 Abs) ensure precise measurements. Wavelength range of 320–1100 nm with ±1.5 nm accuracy, 1 nm resolution, and 0.1 nm reproducibility supports detailed spectral analysis. Its compact design, low weight, and broad operating temperature range (10–40°C) make it ideal for industrial and laboratory environments.
