A degree, held, and the manufacturer's own numbers
The most technical family of the network, and the one where the specification is the product. An immersion circulator is a heater, a pump and a thermostat; what separates models is the stated temperature stability — a figure in tenths of a degree that makers publish — together with the wattage, which decides how long a bath takes to come up, and the maximum bath volume it is rated for. We also compare the pump flow, how the clamp fits different pot walls, whether the display is readable across a kitchen, and the timer behavior when the target is reached. Every temperature and time on these pages is the manufacturer's own published figure. We report them; we do not translate them into food-safety guidance, which is the business of the maker's manual and of your national food safety authority.

1,100 W · 40–90 °C (104 to 194 °F) · 16 L/min · IPX7
The only sous-vide appliance here that publishes a pump flow rate: 16 liters a minute, through a metal propeller on a 45-degree double-inclined spiral wheel KitchenBoss states is unusually quiet. 1,100 W, 40 to 90 °C (104 to 194 °F), IPX7, an LED touch display, SUS304 stainless on everything immersed, and a clamp that stays on the rim when the stick is lifted out.
Best for: A bath that needs stirring properly, and a clamp that does not have to be re-fitted every time.
Sous-vide cooking runs for hours: the appliance's regulation and sealing count far more than its power.
A simple circulator and a container are enough to understand the technique before investing further.
An immersion circulator fixes by clamp or screw onto a wall of a given thickness. The stated clamping range says whether it holds on a stockpot, a plastic tub, or nothing at all.
No. A zip bag lowered slowly into the water has the air pushed out by water pressure, which is enough in most cases.
Always, in a very hot pan and for a few seconds per side. Sous-vide cooks through but browns nothing.
In the order of an hour for a thin piece to several hours for a thick or collagen-rich one. It is thickness, not weight, that governs.
At sous-vide temperatures, no, provided they are food bags intended for cooking. Ordinary freezer bags are not all suitable.
On long cooks, yes: evaporation lowers the level and the appliance eventually cuts out. A ping-pong ball or cling film is enough.
Yes, provided they do not touch and water circulates around each. A separating rack helps a great deal.
Rapid chilling in iced water then cold storage lets you finish later. That is what makes the technique practical for entertaining.
The low temperatures mean respecting the durations given in the cooking tables. It is the point on which not to improvise.
Sous-vide gives a perfectly even cook right through and browns nothing: the final sear in a very hot pan is not optional. A zip bag lowered into water replaces a vacuum sealer, and on long cooks cover the container — evaporation cuts the appliance out.
There is no table here, and the reason is in the listings. Enough of these 18 products name the same row — temperature range — for a column to qualify, and too few publish a figure in it: the column would compare blanks rather than models. Each product page says what its own maker published.
