MINI DIGITAL THERMOMETER
The industry standard aquarium thermometer — stripped back, reliable, and now available in two colours so you can colour-code your tanks. Black probe or yellow probe. Your system, your colour match.
Two Colours. One Legendary Thermometer.
Same bulletproof digital thermometer you have relied on for years — now in two colourways so you can visually organise your tanks, systems, or store displays at a glance.
BLACK Variant
The classic stealth look. Black display unit with black probe — blends seamlessly into darker tank backgrounds and equipment racks. Perfect for broodstock systems, quarantine, or anywhere you want a clean, understated install.
# COLOUR-CODE → BLACK TANKSYELLOW Variant
High-visibility confidence. Yellow display unit with yellow probe — easy to spot at a glance across the fish room. Ideal for grow-out tanks, display aquariums, or store bins where you want the reading to pop.
# COLOUR-CODE → YELLOW TANKSWhy Professionals Choose Mini Digitals
When you are running dozens or hundreds of tanks, you need a thermometer that does not complicate your life. No apps, no calibrations, no nonsense — just plug it in and read.
Unapologetically Simple
No Bluetooth pairing. No firmware updates. No phone apps. One button toggles Celsius and Fahrenheit. That is it. Your staff already know how to use it because everyone knows how to read a number.
Field-Proven Reliability
You have seen these units in fish rooms, hatcheries, and aquarium stores across the world for over a decade. They survive drops, splashes, and the occasional knock because the LCD is recessed and the housing is built solid.
Dual Colour = Dual Purpose
With BLACK and YELLOW variants, you can instantly assign colours to different systems. Black for broodstock, yellow for grow-out. Black for quarantine, yellow for display. Your system, your scheme — at a glance.
Engineered for Fish Rooms
Every feature exists because a fish farmer or store owner asked for it. No fluff — just practical, durable hardware that works when you need it.
Dual Suction Cups
One cup for the display unit — mount it anywhere on the glass. One cup for the probe — hold it at the exact depth you need. Independent placement means the screen is always readable where you want it.
1-Metre Submersible Probe
Fully waterproof probe on a 1-metre cable gives you reach into deep sumps, tall display tanks, and awkwardly placed filtration compartments. Place it where the actual water temperature matters, not just at the surface.
Battery Included (LR44/AG13)
Ready to go straight out of the box — or bag, since we skip the retail packaging. Uses a widely available LR44/AG13 button cell you can grab at any supermarket or hardware store.
°C / °F Toggle
One-press toggle between Celsius and Fahrenheit. No menus, no long-press confusion — just a single button that cycles the display. Simple enough for any team member to operate.
Fresh & Saltwater Safe
The probe and cable are built to handle both freshwater and marine environments. No special precautions needed — drop it in and it reads. Used in hatcheries running everything from trout to coral propagation.
Large LCD Readout
Big, high-contrast LCD digits you can read from across the room. No squinting, no glasses required — designed for quick walk-by checks when you have 50 tanks to scan before lunch.
No Retail Packaging
We ship these units without the wasteful retail box. Less plastic in landfill, lower cost to you, and less time spent opening shrink-wrapped blisters. Because you are buying equipment, not a gift box.
Miniature Footprint
The display unit is barely larger than a matchbox. Mount it on the tank glass and it stays out of the way — no bulky controller boxes, no dangling wires across walkways. Clean and compact.
