Monitoring Internal Temperature When Cooking Sous Vide

[Anonymous Modernist 3761]

Does anyone use a probe inserted into your subject while it's in the Immersion Circulator? If so, what are you using to maintain the vacuum and seal?

Thanks,

Hi,

For the moment I insert the probe through the bag and then put the sealed bag in another bigger one that remains open (open part clip to the side of the bath to avoid water flowing in.) It is not perfect but it allows to keep an eye on how temp evolves without having to buy a probe with a seal tag.

I'm not using a probe myself but according to Douglas Baldwin and other sources you use closed cell foam tape (which is similar to high density foam weather stripping) with a small probe and you keep the probe there.

Does anyone know where to get this tape at? That sounds like the perfect solution...

Polyscience sells it on their site.

Can anyone confirm that this product on Amazon is the same thing?

I'd stay away from that. Plastics used for food prep have different quality standards than those used for construction. It's very possible for chemicals to leech out of that tape that would not be present in the food grade version of that tape.

polyscience website has the tape and a hypodermic probe to use with it

Does anyone have a good recommendation for a probe set-up to use to monitor sous vide cooking? I would like to try to avoid spending as much as the MC recommended ones are, anyone know of a good budget deal?

Luke,

I have a very cheap corded probe thermometer purchased from Target for $10 or $15. It beeps when temperature reaches the set point. The display also shows min/max temps, Fahrenheit or Celcius.The probe is 1/8" dia, with a nice sharp point. Cord is silicone, crimped into the stainless probe, the joint hasn't leaked yet.

Temperature readings are very repeatable, however the calibration is uniformly off by 2.5 degrees (F) - If the display says 140, the actual temperature is 137-138.

If you get one of these, checking and compensating for the error is a must!

FWIW, the manufacturer's point of reference is conventional ovens and dial thermometers which are both an order of magnitude less accurate than that. So I'm fairly sure they consider their product well adjusted.
