I wanted to purchase devices do validate thermometers - contact, infrared/tympanic and non contact (pyrometers).
Can someone advise me what testing equipment is decent for that pupose (in two dimensions : price and quality...)

I was thinking about these devices:
Welch Allyn 9600 plus - maybe there is something more flexible and less expensive?
VOLTCRAFT IRS-350 - maybe there is something more accurate and more medical-oriented?
