Available in Multiple Colors

Originally, we manufactured the Thermapen in gray only. Later we added all the food-safety color-coding versions. Many people in the food industry use color coding to prevent cross contamination by dedicating tools to specific food products. That way, a knife, cutting board or thermometer that is used for say, raw poultry, won't end up contaminating fresh vegetables like salad greens.

Standard Color Code:
Red = raw meat, raw beef and pork.
Blue = raw seafood
Yellow = raw poultry
Green = produce
White = dairy or bakery items

That was the reason we did multiple colors for the Thermapen. Of course most people buy a color variety simply according to personal preference. Even in commercial applications it seems most people buy colors so they can quickly tell who belongs to which Thermapen (blue is Fred's, yellow is Cathy's, etc…)

What is Biomaster?

Biomaster is a silver-based antimicrobial additive that is molded directly into the plastic housing that becomes an integral part of the product to prevent bacteria growth on its surface. The controlled release of the active ingredient provides maximum antimicrobial protection for the life of the product. When bacteria come into contact with a Biomaster protected surface, the silver ions prevent them from growing, producing energy or replicating, therefore they die, inhibiting degradation, discoloration or odors. Biomaster is an additional line of defense between cleanings.*

*Biomaster does not protect the user from disease causing organisms and is not a substitute for good hygiene and/or cleaning.



Thermapen Mk4 FAQ

1. Where can I buy the Thermapen?
You can buy it right here online. There are only a few authorized dealers, (watch out for counterfeit Thermapen look-alikes). There are a few retail outlets in the U.S. and Canada that stock the Thermapen.

2. Why don't more retail outlets carry it?
Most retailers want to more than double their money. The big name chains want the most. If a product costs them $4, they want to charge you $10. The Thermapen is already priced at "Trade Pricing". Meaning, this is the price we sell it to commercial food service users and health departments. And, we offer it to the general public at the same price. Big retail chains would have to charge you much, much more and they'd still be mad that we would take your order at a lower price. The retailers that do carry the Thermapen are not making their normal mark-up so thank them if you buy there!

3. Where can I buy replacement batteries?
The Thermapen Mk4 uses one AAA battery, which are commonly found at Wal-Mart, Target, and other stores.

4. How long should the battery last?
The new Thermapen Mk4 with one AAA battery should give you about 3,000 hours of use. This number is based without using the back light. If you grill a lot at night the number will be reduced.

5. Will the Thermapen tell me when my meat is done?
Not exactly. Instead it (very quickly) tells you the actual temperature and you decide if that is "done". We can give you the USDA guidelines for food safety but you should consult your favorite cookbooks, TV shows and recipes for advice not only on safe temperatures but the best cooking temperatures for flavor and texture. Also remember that individual preference is very important.

6. Other digital cooking thermometers are cheaper. Why pay more for a Thermapen?
In use there's a big difference. Don't take our word for it. Check our Reviews page to read the many reasons written by others. Cheaper thermometers are limited by the technology that they use. These can be mass produced for just a few dollars. On the other hand, the Thermapen is hand-assembled and hand-tested and uses a professional thermocouple circuit design. This design costs more to make than the cheap thermometers.

7. Why is the Thermapen so much faster than other cooking thermometers?
The main reason is the professional thermocouple technology that we use instead of mass-produced thermistor technology. Thermocouples are recommended by the USDA for measurement of cooked meat products and thin portions. Go here to see what a thermocouple means in performance vs. a thermistor. We also use a reduced-diameter needle tip on the probe. Comparable professional meters cost $140 to $300 for the electronics and a similar probe! Some improvements were made in the sensor manufacturing process and the probe assembly in the new Thermapen Mk4 to make it just slightly faster than the original Super-Fast® Thermapen.
