Recommendations for equipment used to validate cold storage units

[duff999]

Hi Folks

I would like to know if anyone has a recommendation of a temperature probe or data logger that I can use to validate our cold storage units. We have several -80 freezers, -20 freezers and cold storage refrigerators that I would like to do some temperature mapping on.

Thank you in advance!

I've worked with this company's equipment before, they make good stuff:
Data Loggers | Onset Data Loggers

The folks at Traceable also make good stuff:
Traceable® Thermometers with Data logging Capabilities

Thanks for the links. Do you know if these can handle temps below -80. This is my first attempt to validate cold storage, are multiple probe available for these loggers?

They both carry ultra low temperature models.
