OHAUS AP50 Series Portable Colorimeter

Fast and Reliable Water Quality Testing for Field Applications

The OHAUS AquaSearcher AP50MM portable colorimeter delivers fast, reliable multi-parameter colorimetric and turbidity measurements specifically designed for field water quality testing. This rugged, single-handed device features an intuitive interface with built-in calibration curves that automatically select appropriate wavelengths from a long-lasting LED light source, enabling efficient field measurements without complex setup procedures. The photometer provides comprehensive testing capabilities across seven fixed wavelengths (365nm, 420nm, 455nm, 525nm, 560nm, 570nm, and 630nm), with photometric measurement range from 0 to 1 Abs and accuracy of ±0.005 Abs at 1.0 Abs nominal. Turbidity measurements utilize nephelometric optical system technology with detection limits of 1 NTU and measuring range from 0-200 NTU, accommodating diverse water quality parameters. The large, backlit graphical LCD display (160×240 pixels) ensures easy real-time result visualization even in challenging field lighting conditions, while the rugged design with carrying case containing all necessary test accessories makes the AP50MM the ideal solution for portable water analysis in remote locations or field environments.

Advanced Data Management with User-Friendly Operation

The AP50MM simplifies field operations through intuitive design features that store commonly used test parameters for efficient field use and allow users to pre-program testing protocols to increase operational efficiency. With capacity to record up to 30,000 datapoints with automatic time and date stamps, the colorimeter provides comprehensive data documentation for quality assurance and regulatory compliance. The device operates on four AA batteries (included) providing approximately six months of battery life at typical usage rates of 25 readings per week, eliminating the need for charging infrastructure in remote field locations. Automatic wavelength selection combined with the long-lasting LED light source reduces operator error and ensures consistent measurement accuracy across diverse water quality parameters. The compact, lightweight design (0.6 kg / 1.32 lb) enables one-handed operation for portability and extended field deployments, while the nephelometric turbidity system and round sample vial compatibility (Ø24mm) provide standardized measurement protocols. Designed for operation in challenging field environments from 4-41°C with up to 85% relative humidity at altitudes up to 2000m, the AP50MM delivers reliable performance in diverse geographic and climatic conditions encountered during environmental water quality monitoring.
