Our Analysis and Test Results
The Precision Cooker Nano is compatible with the Anova app, so you can remotely start or stop your sous vide right from your smartphone. This app also offers you a handy set of pre-configured recipes that you can send right to the machine or an option to create custom recipes to make it easier to cook your favorite meals again and again.
First and foremost, we rated and scored the temperature accuracy and heating abilities of each product, which accounts for 40% of the final score for each product. When it came to determining scores, we looked at how well the Precision Cooker Nano did at maintaining a stable temperature over an hour, how accurate it is, how long it took to initially warm up the bath, and how quickly it regained its set temperature after you added cold food to the container. The Precision Cooker Nano did very well, earning an 8 out of 10.
The Anova Precision Cooker Nano struggled a little bit when it came to heating up 9.5 quarts of cold tap water to 147°F, taking just shy of an hour to accomplish this task, with the fastest models only taking about half of that. The Anova Precision Cooker Nano did recover decently well when we dropped 3 frozen burger patties in the sous vide bath, returning to 135°F after three minutes or so.
The Precision Cooker Nano did thoroughly impress us in our stability test, maintaining an essentially perfectly stable temperature water bath over the course of an hour. We measured this with an iButton data logger vacuum sealed into a sous vide bag, which measures to a resolution of 0.1°F. The Precision Cooker Nano also did very well in our accuracy tests, with the temperature shown on its display only differing from our lab-grade thermometer by an average of 0.38°F when the temperature was set to 135°F and 0.19°F when set to 147°F.
Our second metric focused on how well the Anova Precision Cooker Nano circulated water throughout the vessel, which makes up 30% of the final score for this appliance. We evaluated performance by timing how long it took for measured quantity of dye injected into the bath to become a consistent color throughout. The Anova Precision Cooker Nano has quite an impressive amount of circulation, earning it a 7 out of 10.
The Precision Cooker Nano only took 48 seconds to evenly disperse the dye throughout the water bath — much faster than the 2 or 3 minutes it took some of the slower models. However, the Precision Cooker Nano was still considerably slower than the fastest models, which distributed the food dye in approximately 15 seconds.
Ease of Use
Next, we moved on to evaluating how convenient and easy to use the Precision Cooker Nano is, which is responsible for 30% of the total score for each product. Scores were based on the interface for each sous vide — including its companion app, if there is one — and how easily each product can attach to different containers. The Precision Cooker Nano did exceptionally well, earning a 9 out of 10.
The Precision Cooker Nano has basic manual controls — touch buttons and a digital screen — that are responsive and intuitive. They make a good backup option if you don't feel like using your smartphone to control the sous vide or if someone who hasn't set up the connected features needs to make an adjustment while cooking is underway.
The companion app is also very convenient and straightforward to use but we did occasionally find it to be a little glitchy if the wifi wasn't the best or if we were swapping networks. We liked that you can start or stop the Precision Cooker Nano remotely, look up recipes in the library and automatically have your sous vide follow them, or even create and save custom recipes to get repeatable results once you have fine-tuned your dishes.
The Precision Cooker Nano clamps to the side of the container with a screw action clamp. The screw spins freely and quickly lets you mount it securely to all sorts of vessels.
The Anova Precision Cooker Nano is a great option if you are shopping for a top-tier sous vide and hoping to save some cash.
The Precision Cooker Nano is one of our all-time favorite sous vide machines, pairing excellent temperature accuracy with impressive circulating power all in a much more affordable package than many of the other top-tier models.
