Multifunction Water Quality Tester

Features:
EZ-9909 is a new multi-functional water quality test instrument, which can measure pH, TDS,EC, salinity value and temperature. The measurement range is large and wide, which can measure both for fresh water salinity and sea salt
Low power consumption，Automatic shutdown,The instrument will shut down automatically for 5 minutes without any operation
Automatic temperature compensation function
With backlight function, it can be tested at night
Small size, light weight, easy to carry, can be put into a pocket
The waterproof grade is IP67, at normal temperature and pressure, when the for shell is temporarily immersed in 1M water will not cause harmful effects
