The exciting new eXact iDip 570Smart Photometer System is a 570 nm variant of the original eXact iDip Smart Photometer which was the first handheld photometer to provide 2–way communication with a Bluetooth SMART (4.0) ready Apple or Android smartphone/tablet (patent pending) with the capacity to the most commonly tested water quality parameters. The 570 variant allows the iDip to test parameters requiring a higher wavelength such as Ammonia, Fluoride, QAC, and more. Data is seamlessly transferred between the two devices when paired with the eXact iDip smart photometer using Bluetooth SMART wireless technology that syncs and transmits test results in real time. The eXact iDip photometer is waterproof (IP-67) and incorporates a permanent built-in sample cell which eliminates loose parts, streamlines the test procedure and improves accuracy. The multilingual eXact iDip app is the brain of the system which allows for instantaneous software updates/upgrades, test customization, and mobile sharing of results via email as a CSV file! It comes with 4 tests installed including pH, Free Chlorine, Combined Chlorine and Total Alkalinity. Over 35 additional parameters are available for in app purchase, making the eXact iDipa truly customized experience. Combined with the built in smartphone/tablet GPS function all results include time, date, and location to enhance test integrity. Water technicians appreciate eliminating repetitive data entry tasks while saving time and money. The eXact iDip uses a patented iDip 4–step reagent delivery method, a quick yet safe and easy procedure for water analysis. Select your test then push a button and dip an eXact strip into the 4 ml water sample for 20 seconds using a gentle back and forth motion. Discard the strip and read your results!
