YSI 9300 and 9500 Photometers
Flexible Photometers for the Lab or the Field
Eliminate sample preservation by taking your portable, waterproof
instruments to the field to perform the analysis on-site. All reagents
are safe and easy to use.
Selecting the desired test has never been easier. Simply navigate
among the list of available tests on the screen (favorite tests stay
at the top) of the instrument to choose your test and say “OK”.
The instrument will then walk you through the steps to complete
the test. Simple. Convenient. Accurate.

Features (Model 9300 and 9500):
• Direct-reading concentrations with automatic set up
• Waterproof; IP-67 (floats)
• Large backlit graphic display
• Unique sample tube holder accommodates various diameters
• On-screen instructions
• Multiple languages (English, French, German, Spanish, Italian)
• 100+ test choices on the photometer display
Additional Features (Model 9500 only):
