About this product
The digital aquarium thermometer reads the water from outside the tank: you press it onto the glass with 3M double-sided tape and the LCD shows the current temperature together with the highest and lowest readings of the last 24 hours. The display covers 32°F to 140°F, switches to Celsius with a hidden side button, and works on freshwater and saltwater tanks. Readings sit within 0.5°F, and the unit runs on a battery on its front, with a spare in the pack.
Checks before you stick it on the glass
The thermometer suits freshwater and saltwater aquariums (F3). The stated tolerance is 0.5°F, which is the margin to expect between the reading and the true water temperature (F2).
It mounts on the outside of the glass with 3M double-sided tape, so the surface needs to be a glass panel rather than a frame or lid (F10). The screen has no backlight, so the numbers are read in ordinary room light (F7).
What comes in the box
- One hygger thermometer in blue, model HG073 (S1, S2)
- A battery already fitted in the unit (F12)
- A spare battery (F12)
Fitting it and clearing the record
Press the thermometer onto the aquarium glass with the 3M double-sided tape; no wire runs from the unit to the water (F10, F11). The battery sits on the front, and the cover slides off so a replacement goes in without peeling the thermometer off the glass (F13).
To reset the stored highs and lows, long-press the buttons and the record clears (F9). The unit records the maximum and minimum of the past 24 hours (F8).
What can you read on the screen at once?
The LCD shows the current water temperature alongside the memorized maximum and minimum for the last 24 hours, all on the one screen (F5).
How do you change the display from Fahrenheit to Celsius?
A hidden button on the side of the unit switches the unit between ℃ and ℉ (F6).
Does the thermometer need a cable into the tank?
No cable is needed; the cordless unit holds a built-in smart microchip and an aluminum alloy sensor (F4, F11).
Can it be used on a saltwater aquarium?
Yes, the thermometer is suitable for both freshwater and saltwater tanks (F3).
How close are the readings to the real temperature?
The stated tolerance is within 0.5°F (F2).
How the readings and the housing work
The display covers 32°F to 140°F and holds a tolerance of 0.5°F (F1, F2). Both the current reading and the 24-hour maximum and minimum stay visible together (F5, F8).
A hidden button on the side of the housing switches the readout between ℃ and ℉ (F6). The cordless body carries a smart microchip and an aluminum alloy sensor inside, and the battery on the front slides out for replacement (F4, F13). There is no backlight on the screen (F7).
