Thermostat Types for Hova-Bator Incubators

Learn about the various thermostats available for the Hova-Bator Incubators.

As incubators become less expensive, the easiest way for a manufacturer to save is on the thermostat. Now, does this mean the less expensive thermostats don’t work … no, they work, but they’ll require more attention on your part to ensure that they’re maintaining the correct temperature at all times. Let’s take a closer look at types of thermostats used with Hova-Bator incubators

Different Thermostats Offered in the Hova-Bator line of Incubators

The 1602 and the 1583 are two models that use a thermostat wafer to maintain the proper temperature. A thermostat wafer is a very simple machine that has been used for decades to accurately maintain temperature. It consists of a metal “wafer” that contains a small amount of ether. This ether expands and contracts and causes the metal wafer to expand and contract. As the wafer expands and contracts, it hits a micro switch. This switch controls the heating element, turning it on or off.

How a wafer thermostat works.

Wafer thermostats generally require a bit more maintenance because they are not as accurate as we would like. It seems that you need to check the temperature and adjust the settings very frequently with these thermostat types. How frequently? I think that seems to depend on the conditions outside of the incubator. However, when I use this style, I try to check it as frequently as I can, and keep notes on how I’ve adjusted the wafer’s position in relation to the switch.

The 2362E model incubator uses a dial style thermostat. This is not as accurate nor as easy to use as digital style thermostats, but is still much easier and accurate than the wafer style. With these incubators, you simply turn the dial to adjust the incubator’s temperature up or down. These thermostats use a small electrical conductor that will maintain the temperature. It does not have a digital readout like we will see next but is still more accurate than the wafer style. You will to experiment with your dial settings see how they affect the temperature inside the incubator: Adjust and then observe.

The 1588 model is the most popular and easiest to use, with a digital thermostat that controls the incubator’s temperature. What does this mean? Instead of using a dial or having an adjustment screw, this unit has a very simple two-button system: You simply hit the “up” arrow to increase the temperature, or the “down” arrow to bring the temperature down. As you can see in the photo above, you can adjust this to the exact temperature that you’re looking for. As with all incubators, I do suggest having a backup thermometer inside just to be certain the thermostat is reading correctly. If, by chance, this thermostat does start showing the wrong temperature, there are easy-to-follow instructions included to recalibrate the thermostat.
