Easy to use with consistent results!

Very fast shipping, nice website

We lost our power cord in a move, and it was quick and easy to get a new one. Thank you!

Shipping was fast,

This instrument is much easier to use than the individual Hanna Checkers. It will guide you step by step on the screen as to what you need to do for each type of test. It also. Integrates with the Hanna app to record test results. I highly recommend the Marine Master Multiparameter Photometer.
