We used to have the big time wheel type to measure temperature and now I would like to get the kind that I can leave inside the Fresh Food or Freezer.
Some you bring back to download on a PC and some work with smart phones.

I would like to know which type are working well for you guys &n gals

interesting USB Temperature sensor / recorder $6.50 shipped
(while connected to laptop)

stand-alone version ... about $ 35

the included software may be a little "hokey"
and the temperatures aren't necessarily accurate (but repeatable)

I carry the Supco (older ) model SL200 and the newer SL300 the newer one will record for a month at 5 ? minute intervals and can vary from one second to once a day ( need to verfy, unit out in the van )....pricey at $ 135 clams but I haven't found a more reliable unit out there

Got the supco Sl300 few weeks ago and did my first logging last week. Fridge repair where the only problem was a intermittent fridge light staying on. Replaced the switch. Customer's husband refused to believe the fix was as simple as that. Large fridge, took about 48 hours to stabilize but hubby didn't quite trust the simplicity of the repair. So used the logger for a week. Results 38.2 degrees with no spikes. Emailed the graph. Not unlike your graph posted in http://www.applianto...d-thermistor-5- but I did include humidity and dew point just for the coolness. Great tool and adds a wonderful professional touch. Thanks for the tip, Sensei!

I use the SL200 as well. Whatever Im looking at, after 2 days Ive got enough of a track record to read the problem out like a book. Indespensible for those intermittant problems, but you do need to understand the box so you can interpret the data

I use the LogTag from Microdaq. One base and as many credit card sized recorders as I want to own. I got it a few weeks ago and it's saved a lot of money. I can now adjust those expensive cold controls rather than replacing (some) of them. Excellent software. I wanted to upload an image of sample data record I recorded but can't seem to find where. Anyway, it's the best one I've used so far. Only $33.00 for the recorders and I think about $55.00 for the base.

I use the Supco LOGiT data logger:

looking at the Extech Sd200 3-channel logger. They can record to an sd card in excel format. Thinking about them since no special software is needed and I can examine the info on my android tablet at customer's house without needing a windows laptop.

Ooo, sounds nice. Can you post a link?

looks like amazon and sears has the best price at $229

 

 

Now if you want to record fridge, freezer , dryer and oven temps all at the same time, you need the 4 channel model for $350 ...lol

The only problem I have with these fancy  data loggers is they will attract the attention of customer's nerdy, lying ("i didn't touch it mom") son.  The Supco  model I have  is no bigger than a cigarette lighter and can easily be hidden in a fridge/freezer. Down side...only one channel and I have to connect it to a pc to set it up and to retrieve the data.  Decisions...Decisions
