To Measure Is To Know

Mailbag time!

I got this HT-9815 4 channel K-type digital thermometer from eBay seller PerfectPrimeUSA (which of course is located in Hong Kong). Got it for a mere $26 (including free shipping) and four (cheap) thermocouples included. And it actually seems to work fairly well! Refresh rate is about once per second, it remembers lowest and highest temperatures measured as well as average temp. It can switch between degrees Celsius, degrees Fahrenheit and Kelvin and it actually appears to be reasonable accurate. The backlight is piss-poor (one LED located on the left side) but for this kind of money I can't complain really. Just shipping it back to Hong Kong would probably cost me more than what I've paid for it :)

I'll crack it open tomorrow, see what makes this thing tick, and I'll do some measurements with the oven.
