The AVAIN LABS® Microprocessor Photo Calorimeter AL-31D is a compact, reliable, and easy-to-use laboratory instrument designed for accurate colorimetric analysis and photometric measurements. Featuring advanced microprocessor-based operation, the AL-31D is suitable for routine analysis in chemical laboratories, pharmaceutical laboratories, educational institutions, research laboratories, water testing laboratories, and quality control facilities.

The instrument is equipped with 8 filters and provides direct measurement of results in Concentration (%), % Transmittance (%T), and Optical Density (O.D.), helping simplify routine laboratory analysis. Its built-in memory can store up to 3 standards, reducing the need for frequent standardization and making repetitive testing more convenient.

The automatic zero-setting facility improves ease of operation, while the instrument's 1 mL solution measurement capability makes it suitable for applications where sample volume is limited. Results and operating information are clearly displayed on the easy-to-read 16 × 2 LCD display.
