Product Description
Field crews and teaching labs can run more than 50 water quality tests with a single handheld instrument. The OHAUS Aquasearcher AP50MM Portable Multiparameter Colorimetric Turbidimeter combines seven LED light sources with built-in standard curves for quick on-site results.
This listing is for OHAUS item number 30853394: Aquasearcher Portable Multiparameter Colorimeter and Turbidimeter a-AP50MM-B, 7 Wavelengths. Fixed wavelengths of 365, 420, 455, 525, 560, 570 and 630 nm cover 0 to 1 Abs with ±0.005 Abs accuracy, and a nephelometric channel measures turbidity from 0 to 200 NTU. The unit reads 24 mm round vials, stores 30,000 results with date and time, and shows data on a backlit 160 x 240 graphical LCD. It runs on four AA batteries with auto-off for about six months of typical use and comes in a carrying briefcase. Add it to your LIGHT LABS order and keep your lab running with genuine OHAUS equipment.
