Accuread Digital Nutrient Thermometer - Reservoir Temperature Monitoring on a Budget
Best for: Growers who need to keep an eye on reservoir temperature but don't want to spend on a multi-function meter.
Our thoughts
Reservoir temperature gets overlooked constantly, and it shouldn't - too warm and you're inviting root rot and algae, too cold and uptake slows right down. This is the cheapest possible way to actually know what's going on in your tank instead of guessing. No frills, just a number.
The Accuread Digital Nutrient Thermometer is a simple wired-probe digital thermometer built specifically for monitoring nutrient solution temperature in hydroponic reservoirs and tanks. The probe sits on the end of a 97cm cable, long enough to reach into most reservoirs while the digital display stays outside the tank where you can actually read it.
It's a single-purpose tool - it reads temperature, nothing else - which keeps it simple to use and very cheap to buy. If you're already managing pH and EC separately, this fills the one gap those meters often don't cover well: a dedicated, easy-to-read solution temperature reading.
How it compares
This sits at the budget end of reservoir monitoring, well below combined pH/EC/temperature meters.
- Vs Bluelab combo meters (pH/EC/temperature): Bluelab meters are considerably more expensive but give you three readings from one probe; this Accuread does one job for a fraction of the price.
- Vs analogue dial thermometers: a digital display with a probe on a cable is easier to read at a glance and easier to position than a dial thermometer clipped to the tank side.
- Vs aquarium-style digital thermometers: functionally similar wired-probe design, but this one is sold and calibrated for hydroponic reservoir use.
If all you need is a reliable reservoir temperature reading, this does that job without paying for features you won't use.
Usage guidance
Simple to fit and use.
Placement
Drop the probe end into the reservoir so it sits fully submerged in the nutrient solution, away from the direct pump outlet where readings can be skewed by turbulence.
Reading
Keep the digital display outside the tank, ideally somewhere you'll actually glance at daily rather than tucked out of sight.
Target range
Most hydroponic crops do best with reservoir temperatures in the high teens to low twenties Celsius - if you're regularly seeing readings outside that, look at reservoir insulation, chillers, or heaters depending on which direction you're drifting.
Technical specifications

Who this is for
- Growers on a budget who want reservoir temperature monitoring without a combo meter
- Anyone troubleshooting root health issues who needs to rule temperature in or out
- Growers running multiple reservoirs who want a cheap thermometer for each one
A sensible add-on for any reservoir-based hydro system, regardless of how basic or advanced the rest of your setup is.
Our take
At this price there's no real reason not to have one in every reservoir you run. It won't tell you pH or EC, but it answers the one question a lot of growers never actually check.
Does exactly what it should, day in, day out - cheap enough to buy a spare.
