[Samurai Appliance Repair Man]

I've run into a couple of situations lately where I realized that I needed a way to log temperature data inside a refrigerator for at least 24 hours to get a clear picture of what's going on inside that box. Now, for the first time ever in theaters, the Samurai reveals his personal technique for capturing and logging temperature changes inside a refrigerator or freezer. Topics covered include:

- Why use a temperature data logger?

- Which temperature data logger does the Samurai use?

- How do you set up and use a temperature data logger?

- Interpreting temperature data logger data and graphs



Here's the temperature data logger that I use:

and you'll need this software kit to get the data to your Windows PC:

For speed, efficiency and to be able to check switcher behavior in dual evap fridges, it's a good idea to have two loggers or a two channel logger like the one the Samurai uses. Provide them with identical settings and place one in each compartment. I already owned one supco sl300th logger and purchased another so i could do both compartments or even two standard fridges at the same time. Maybe one day i can get the advanced version The Samurai has. The small model I use can be set on standby and placed in a little pocket in my toolbag, awaiting to be used at a moments notice.

An added benefit of having a logger is to use it as a "punter"... ie I have no idea what's going in this fridge... got to ask the folks on Appliantology... so i tell the customer "I need to data log your fridge for a few days".. pull out the logger, press the button... and signal a temporary, yet face saving, retreat.

The sl300th also does humidity. I probably could have saved money if i only got the sl300t model without humidity monitoring, unless someone explains to me what i'm looking for when reading the humidity graph.

I use NASA-brand Temperature Data Loggers.

 

Great tool---temps are skewed/doctored *northwards* of 30 to 40 percent.
