Key Features: Mercury-Free, Accurate, and Safe for Freshwater and Saltwater Tanks.
-
Mercury-Free & Fish-Safe – The non-toxic liquid column gives fast, reliable readings without endangering freshwater or saltwater inhabitants.
-
Truly Floating Design—The weighted base keeps the thermometer upright for at-a-glance temperature checks; no clips or brackets are required.
-
Removable Suction Cup Included—Optional mount lets you anchor the unit to any inner tank wall for extra stability; detach anytime to let it drift.
-
Easy-Read Vertical Scale – High-contrast °F/°C markings from 30°F to 120°F (0°C–50°C); colored liquid pools at the bottom for instant accuracy.
-
Compact & Tank-Friendly – Measures only 0.5″ W × 0.8″ D × 4.25″ H; disappears into the background yet remains highly visible when you need it.
-
Ready to Use – Simply rinse, drop in tank vertically, and wait 30 seconds; any temporary liquid separation self-corrects once upright.
