ATAGO PAL-31S Formic Acid Refractometer

PAL-31S is a digital handheld refractometer specifically designed for measuring formic acid aqueous solution concentration. With its wide measurement range of 0.0-90.0%, it measures both dilute and concentrated formic acid solutions with ±1.0% accuracy. Requiring only 2-3 drops of sample and delivering results in approximately 3 seconds, it enables significant time savings in production lines requiring rapid quality control.

The instrument features an IP65 water-resistant metal housing, ensuring safe operation in field and industrial environments. Automatic Temperature Compensation (ATC) reduces measurement errors caused by ambient temperature fluctuations. Powered by 2 × AAA batteries with compact dimensions (5.5 × 3.1 × 10.9 cm), it provides excellent portability.

It is a practical solution for chemical production, textile dyeing, leather tanning, and agricultural applications where rapid and reproducible monitoring of formic acid concentration is required. Supplied with calibration certificate.
