Default Those chinese make some bargain thermometers

So Im really excited because Im about to do my first partial mash recipe and my digital thermometer just came in. So sorry if Im rambling. But I ordered a digital thermometer on ebay for an unreal price of $1 plus $2.95 shipping not realizing that it was coming from China, until I got this email.

Well I laughed at this for a while and thought Id share it with you guys. And it came in today and I shoved it under my arm pit, gave it a minute, and it read 98.4 degrees, not bad. It took 15 days to arrive in Boston but for a total of $3.95 its definitely worth it. Just search "Digital Cooking Food Probe Meat Thermometer Kitchen BBQ" on ebay.

Cheers

Your going to brew with a $4 thermometer? I believe I would check more than my armpit temp.

Try ice water and boiling water. And if you have another thermometer, check that they both read within a degree or two of each other.

1+ on the ice water. We run a commercial kitchen at our facility and that is how the Health Dept. tests our dial thermometers.

I was going to suggest another body orifice but then you might not want to brew with it.

LOL

btw - It's crazy how some Ebay sellers are nutz to protect that 5 star rating. I ran up against one of them who sold me a POS $10 item and I had to spend $5 in shipping it because it was defective. They went crazy when I left them bad feedback.

In the lab we use ice water and boiling water and always compare to a NIST calibrated thermometer. You need the extremes (0C and 100C) to determine the linearity of the device. While it may be accurate at 0C, the boiling temps could be a few degrees off.... In an ideal world, the device will be linear throughout the entire range you wish to measure.

Thats an awesome score, but I would make sure to calibrate it before every brew day. The cheapies are known to eventually go bad and you dont want to mash 10 high or low
