Press Release Summary:

Using EZ-3™ Reagent Delivery Method, eXact® Micro 20 performs on-site testing for over 35 water quality parameters without lookup tables, drops, or color matching. Unit self calibrates and automatically selects optimal wavelength, either 525 or 638 nm, for each parameter. Test procedure only requires user to push button and dip eXact® Strip into built-in sample cell for 20 sec. Waterproof meter is compliant with USEPA levels for free/total chlorine and chlorine dioxide testing.

Original Press Release:

Handheld Dip Strip Photometer - The Ultimate Water Quality Tester - .

The ultimate water quality tester  - The eXact® Micro 20 dual wavelength photometer uses a patented test procedure for quick and accurate water quality testing results.

The eXact® Micro 20 dual wavelength photometer is the ultimate water quality tester delivering design and engineering with the latest patented technologies to deliver sustainable water testing solutions that cost less. The eXact® Micro 20 is waterproof (IP-67) and quickly does on-site testing for over 35 direct read water quality parameters without lookup tables, counting drops or matching colors. It features a narrow band wavelength filter for optimal accuracy, long-life LEDs, and a built-in cell for ultra-performance. Each parameter stores the 20 previous results for a total of over 600.

This high quality unit self calibrates (no returning it to the manufacturer) and automatically selects the optimal wavelength (525 nm or 638 nm) for each parameter. The meter uses our patented EZ-3™ Reagent Delivery Method for streamlined testing. Simply push a button and dip an eXact® Strip into the build in sample cell for 20 seconds (liberating the reagents), discard the strip and read the results! It provides smooth and precise reagent dispersion into samples without leaving suspended solids that adversely affects test results. Compliance with USEPA levels for Free/Total Chlorine and Chlorine Dioxide testing attests to the meter’s quality. 

The eXact Micro 20 dual wavelength photometer is available in three portable kits packed a sturdy case with eXact® Strip reagents. It’s the preferred tool for accurately and quickly testing water quality. Try it now risk free with our industry leading 30-day money back guarantee.
