Generic needle hydrometer
Durable clear plastic hydrometer.
Accurate and easy to read.
Designed for use in warm water aquariums (18-28C).
Readings are temperature-corrected & accurate to +/- 0. 002 specific gravity units which range from 1. 000 - 1. 030 specific gravity.
0-40 salinity ppt.
It is optimum to be put into below 6" deep water, so it can avoid the error from the oil slick.
Fit for brackish and marine aquariums.
Perfect for testing both salinity and specific gravity of your brackish and marine tank.
The easy-to-read swing-arm pointer and extra wide stable base provide an accurate test result.
