Chickens can be wonderful pets, but they are also good side-hustle. You will need to expand the flock at one point. You can achieve this in either one of two ways; naturally or artificially using an incubator.

Before reviewing the top 7 best incubator thermometers and hygrometers, let’s explain these two options.


Going the Natural Way

First, you can let nature take the course. Here, the laying hen stops and goes broody. It then sits on the eggs she laid or stole for 21 days to hatch them. The hen provides optimal temperature and humidity for the eggs to hatch into healthy chicks.

A few problems can arise if you go with this option, though:

  • Broody hens will stop laying eggs. Is this good news for those who keep chicken for egg collection? Certainly no, it isn’t. If a rooster isn’t involved, the hen may sit on the eggs for the rest of its life. That means no more eggs for the period.
  • Broody hens are likely to ‘infect’ others with their broodiness. Soon, the entire flock will be brooding. Egg production will cease completely.
  • Broody hens are territorial and aggressive. They will puff their feathers out and screech at you and anything else that approaches their nest. Some breeds become so fierce; that they can even bite children and pets, injuring them.

Using an Incubator

Although nature provides the best incubator, the disadvantages we discussed limit its use. Luckily, technology has made it possible to use an artificial incubator. Your chicken can lay eggs all year round. Thus you can start a new flock without having to interrupt your business.

However, incubators cannot work alone. They need humidity, heat, and other factors to work properly. All these factors must be maintained within a narrow range. Put differently, you must continuously monitor the aspects if you must get the best results.

Thus you will need the best incubator thermometer and hygrometer. Our aim here is to provide you with in-depth information to allow you to make an informed choice. In the end, you will be able to buy the best thermometer or the best hygrometer.

Our Comprehensive Buyer’s Guide

The reason you are looking for the best incubator thermometer and hygrometer is best known to you. Regardless of your reasons, you still need the best. Several factors contribute.

Here is a list of those factors at a glance:

  • The intended use
  • Accuracy and response
  • Power source and battery life
  • Quality of user-interface
  • Alerts and remote monitoring
  • Data storage and logging

Let’s now dissect each of these factors. If you have already found your match, well and good. If not, they will guide you into making the right decision.

1. The intended use

Incubator thermometers and hygrometers aren’t specifically for incubating eggs. You can also use it with a host of other home appliances and installations. Even when you intend to use it in hatching eggs, it’s important to decide based on the type of eggs.

For instance, some incubator sensors for better suited for hatching chicken eggs. Others may be ideal for incubating reptile eggs. Luckily, most brands are versatile. Therefore, they can be used successfully with multiple applications.

2. Quality of the user-interface

The first thing you will see on a digital electronic product is its display. Therefore, you must consider the user-interfere of each incubator thermometer and hygrometer of interest before you settle on buying it. Is the display bold, clear, and easy to read?

Older users and those with problems seeing need large and bold displays. Check the size of the LCD, the font, and the size of the writings. When you see it displayed on manufacturers’ websites or product descriptions may not be accurate. Conduct further research by reading customer reviews.

3. Accuracy and response 

The success of any artificial egg hatching depends on how well you maintain the conditions within the incubator. Temperature and humidity should be monitored closely. Any deviation from the optimal heat and humidity embryos require to mature, and hatch can result in low hatching rates.

You will see accuracy ratings on product descriptions. These are mere claims by manufacturers, marketers, and distributors of vital devices. You need to do your research. Visit user forums, review sites, and owner’s websites.

When shopping, look for a hygrometer rating which is given as ±% RH. The unit represents the margin of error the sensor has. The most accurate humidity sensors currently in the market have an error margin of 1±% RH. They are the best, but even those that have 2-4±% RH are still sensitive enough.

The accuracy range for temperature is in the order of ± oC or oF. An error margin of ±2 to ±10 can is acceptable. Lower error rates are associated with better accuracy. You must keep that in mind when shopping.

The refresh rate is also very important. It allows you better to monitor the small changes in humidity and temperature. Thus you can adjust any conditions by dehumidifying or humidifying the air. Best quality hygrometers have a refresh rate of 10 seconds.

4. Power source and battery life 

Incubator hygrometers and thermometers are electric devices that work only when powered by security. This can happen in either one of two ways: wirelessly through a battery or through a power cord.

A battery-powered model is portable and convenient. The batteries have low power and are not that durable. Those with cords must be plugged into the power source. Those cables can be cumbersome, especially those that have corded probes too. Choose according to your needs.

5. Alerts And Remote Monitoring 

Unfortunately, only high-quality, often expensive models have alerts and remote monitoring capabilities. But this feature is invaluable. Monitoring the conditions in the incubator remotely through an app can help you better manage the hatchery.

The alerts will help you know if the levels you pre-set have been exceeded or otherwise. Reacting quickly to any changes will make a big difference in the success rate of your incubator. You will spend a little bit more, but it’s a great feature you can’t afford to ignore.

6. Data Storage And Logging 

Storing data about the temperature and humidity is crucial. You get the chance to have a historical overview of the humidity levels in the incubator. The data can be stored over long periods or for just a couple of hours.

For example, some models store high and low readings over 24 hours. Most affordable models, however, do not offer any storage at all. You will have to choose depending on your budget and your needs.
