Hey Guys,
I am trying to purchase a reference thermometer. We calibrate our probe thermometers on a daily basis using the ice and hot water method however, we don't have a certified reference thermometer. I tried looking at NIST Traceable thermometers but the shipping cost is more than half the cost of the thermometer. I am finding thermometers which are NSF certified with inexpensive shipping costs but I am unsure of the difference between the two. Does it matter if I use one or the other? I was looking at the fillowing two options:
