What is the best thermometer on the market. One that is not made in China and would be used by Scientist that have to be 100% correct. Vic

I am sure there are many sources. Here is one source of handheld temperature measurement devices I have used.

A search of the web should turn up a number of hits. Search for "precision temperature measurement devices" or "temperature measurement instruments for science" or etc.

Thanks, I've looked through all that. I'm looking for someone to recomend one they have used and trusted on big and costly indevers. Vic

For what temperature range? What material are you measuring? Air, liquid, surface, etc? Fast-changing temps or slow-changing temps?

How much do you want to spend? All about cost. The higher the accuracy, the higher the cost. The better able to respond to fast changing temps, the higher the cost usually.

Temp range is important. Thermistor devices work great for example in the "herp-related" temp ranges. If that is your application, consider a handheld with thermistor probe.

Here is an economy one that has all the features you may need, such as min/max recording and interchangeable probes with no recalibration. Accuracy is darn good (not the best, but better than many you see in stores). Check it out. www.eutechinst.com/brochures/temperature_handhelds/ecoscantemp4.pdf

Temp. inside egg containers inside a incubator for tortoise eggs. Full time inside probe or wireless so I dont have to open. I'm trying to improve on a 2F degree flux. Thanks but got the information on the Burmese Python Forum, were the masters of incubation for herps go back 30 yrs. Simple solutions for complex life creation. From a liquid to a fully developed prehistoric beast in 64 days. Its been going on in nature in an above ground nest built perfectly through thremo controled mixing and reajusting forest floor materal to produce a warm/moist but cooler than the outside hot and wet environment were the species survives inspite of nature's cruel and inefficient results for 30,000 years.

CORRECTION 30,000,000 yrs* (Eocene stem) pritchard p311 ency.of turtles.vm

Ah, I see.
Look for something with a NIST rating for the best in accuracy.

Also, as you know, these reptiles use large mass (the ground) to keep the egg temps constant.

In captivity in a small incubator, even a great temperature controller and heating system cannot necessarily maintain to 1/10 of a degree unless that air temp in the room stays constant or the incubator is very well insulated.

Those thermometers they sell at Radio Shack and other places for $20 or so will never have the accuracy you look for.
