6 Best Incubator Thermometers For Hatching Chicken Eggs For Peace of Mind
Precise temperature is key to hatching. Discover the 6 best incubator thermometers for reliable readings and worry-free incubation for a successful hatch.
You’ve done everything right: sourced good fertile eggs, cleaned the incubator, and set it up in a quiet corner of the house. Yet for the next 21 days, you’re haunted by a single question: is the temperature really what the display says it is? A reliable, independent thermometer is the single best tool for ending that anxiety and giving you the confidence you need for a successful hatch. Let’s look at the best options to get you that peace of mind.

Why Your Incubator’s Built-In Gauge Isn’t Enough
The digital display on your incubator is a great starting point, but you should never treat it as the absolute truth. These built-in sensors can be off by a few degrees right out of the box, or they can drift over time. It’s not necessarily a sign of a bad incubator, just a reality of mass-produced electronics.
Think of it this way: a single degree can be the difference between a perfect hatch and a disappointing one. A temperature that’s consistently two degrees too high can lead to premature hatching and physical deformities. Two degrees too low, and you’ll see late hatches with weak, unabsorbed yolks.
The goal isn’t to replace the incubator’s thermostat, but to verify it. An independent, high-quality thermometer acts as your second opinion. It gives you the real data you need to adjust your incubator’s settings accurately. Trust, but verify is the mantra of successful hatching.
Govee H5075: Smart WiFi Monitoring on Your Phone
Monitor your home's environment with the Govee Bluetooth Hygrometer Thermometer. Track temperature and humidity remotely via the app, receive instant alerts, and export up to 2 years of data.
For the hatcher who wants data at their fingertips, the Govee is the answer. This isn’t just a thermometer; it’s a complete monitoring system that connects to your home’s WiFi. The major benefit here is obvious: you can check your incubator’s temperature and humidity from anywhere using an app on your phone.
This is a game-changer if you work away from home or can’t be physically present to check on things. The app will send you an alert if the temperature or humidity goes outside your preset range, letting you know about a power outage or failed heating element instantly. This early warning can save a hatch.
The Govee also stores historical data, allowing you to see trends over hours or days. Did the temperature dip overnight when the house got cold? You’ll know for sure. The only real tradeoff is the reliance on technology—it needs WiFi and a smartphone—and a slightly higher price point. But for pure, unadulterated peace of mind, it’s hard to beat.
Brinsea Spot-Check for Calibrated Accuracy
If you’re looking for the undisputed source of truth, the Brinsea Spot-Check is it. Brinsea is a leader in the incubation world, and this thermometer is built for one purpose: providing a hyper-accurate reading. It’s calibrated for precision, which is a step above the typical consumer-grade thermometer.
You don’t leave this thermometer in the incubator 24/7. As its name implies, you use it to "spot-check" your other instruments. Before you set your eggs, you place the Spot-Check inside for an hour to see how its reading compares to your incubator’s display and your primary digital thermometer. This tells you exactly how much of an offset, if any, you need to account for.
It’s a simple, rugged tool with a large, easy-to-read display. It lacks the bells and whistles of a smart thermometer, but it delivers what matters most: confidence in your numbers. Think of it as the reference tool you measure everything else against.
AcuRite 00613: A Reliable Digital Readout
Easily monitor indoor comfort with the AcuRite thermometer and hygrometer. It displays temperature and humidity at a glance, tracking daily highs and lows, and offers versatile mounting options.
The AcuRite 00613 is the dependable workhorse you see in countless hatching setups, and for good reason. It strikes the perfect balance between affordability, reliability, and features. It provides a clear digital display of both the current temperature and humidity, along with high and low records for the past 24 hours.
Its most important feature is the design. The main display unit sits outside the incubator, connected by a thin wire to a remote sensor probe. This is crucial. It allows you to place the sensor probe exactly where it needs to be—at the level of the eggs—without having to open the incubator to read the temperature. Every time you open the lid, you lose heat and humidity, so this design minimizes disruptions.
This thermometer is a fantastic primary monitoring tool. It’s not as fancy as a WiFi model, but it gives you all the essential data you need at a glance. For most hobbyists, the AcuRite provides the perfect combination of function and value.
ThermoPro TP50: A Great Value Hygrometer
If you’re on a tight budget or running several small incubators at once, the ThermoPro TP50 is an excellent choice. It’s incredibly affordable and delivers surprisingly good performance for its price. You get a clear, simple readout of both temperature and humidity in a compact package.
The main tradeoff with this model is its all-in-one design. The entire unit has to go inside the incubator, which means you have to open the lid to check your readings. This isn’t ideal, as it causes temperature and humidity fluctuations. However, it’s a far better option than relying solely on a questionable built-in gauge.
For small tabletop or DIY incubators where space is tight and you want a quick, cheap verification tool, the TP50 gets the job done. It’s a massive step up from having no secondary thermometer at all.
IncuTherm Plus: Designed for Incubator Use
Many digital thermometers are designed for general household use, but the IncuTherm Plus is made specifically for the harsh, high-humidity environment of an incubator. This purpose-built design gives it a real edge in longevity and reliability over time.
Like the AcuRite, it features an external display with a wired probe, allowing for proper placement at egg-level without disturbing the environment. Its probe is often better sealed against moisture, which is the primary killer of cheap electronics in an incubator. It also typically includes a min/max temperature memory, which helps you see if your temps remained stable overnight.
Choosing a tool designed for the job is always a smart move. The IncuTherm Plus is a solid, mid-range option that offers durability and features tailored directly to the needs of hatching eggs.
Zoo Med Digital Thermometer for Small Spaces
Don’t overlook the reptile hobby for great hatching tools. The Zoo Med Digital Thermometer is designed for terrariums, but it’s fantastic for very small or homemade incubators. Its key advantage is its incredibly small probe on a very long, thin wire.
This tiny probe can be snaked into the tightest of spaces without disrupting airflow or taking up precious room needed for eggs. If you’re using a small Hova-Bator or a DIY styrofoam cooler incubator, this is often the best physical fit.
Most models are temperature-only, but that’s the most critical variable to track. It’s a simple, focused, and affordable tool that solves the problem of monitoring temperature in a confined space better than almost anything else.
Calibrating and Placing Your New Thermometer
Buying a great thermometer is only half the battle; using it correctly is what ensures a good hatch. Placement is everything. The sensor probe must be positioned at the same height as the tops of your eggs. Don’t let it rest on the incubator floor or touch a wall or heating element. You need to measure the temperature the embryos are actually experiencing.
Next, take a moment to calibrate your new tool so you can trust it completely. The easiest way is the ice water bath test. Fill a glass with crushed ice and add just enough cold water to fill the gaps. Submerge the probe (not the whole unit!) in the slurry for a few minutes. It should read 32°F (0°C). If it reads 33.5°F, you now know it reads 1.5 degrees high. You can apply that knowledge to your incubator readings.
This simple check removes all guesswork. Knowing your thermometer’s specific offset turns it from a good instrument into a precise, reliable partner in your hatch.
Ultimately, the goal isn’t just to measure temperature; it’s to have reliable data that lets you make the right decisions. Whether you choose a high-tech WiFi monitor or a simple, accurate spot-checker, this small investment is your best insurance policy. It protects your larger investment of time, effort, and valuable eggs, and paves the way for the rewarding sight of a successful hatch.
