BF2S Forums What are they called and where do I buy one?

So I have this temperature monitor Velcro'd to my case, it runs on a watch battery when system power (4pin molex) is of, however theres no blue backlight... thats how i describe it...

The thing is, there is no name on it, and I got it from www.coolerguys.com a LONG time ago when I first built my system... anywho it came up in a conversation and my dad wants one to run some specs on a TV lift systems motorbox tempature because he just added a heatsink for display purposes

(As simple as I can put it... He wants to monitor tempatures on something other than a computer, with no 4pin molex system)

An ambient monitor wont work, the one I have has a plastic film on it (where the sensor is) which is exactly what he wants, so he can stick it between the motor (or whatever it is) and the heatsink plate...

It also needs to run on a charge, or battery's (watch battery is O.K.)

It also doesnt need to be fancy



I looked on Newegg but wasnt sure what to search for, so I got no good results...
I also looked on coolerguys, and again, wasnt sure what I was looking for (as far as a name)

Thanks all

any help will be appreciated
