It’s easy to select the right thermometer for the task at hand. Start with the requirement that is most important to you and look for the recommendations under that category.

Accuracy:

• Calibrated Thermometers—Fractional Degree
• Mercury Thermometers, Total Immersion
• Enviro-Safe® Thermometers

Low Cost:

• BASIX Spirit-filled Thermometers

Safety:

• Enviro-Safe Thermometers
• Teflon-coated Mercury Thermometers

Durability:

• 6" (165 mm) Enviro-Safe Thermometers
• 8" (203 mm) Spirit-filled Thermometers
• Teflon-coated Thermometers (Spirit-filled)

Immersion: (The two types of thermometers are not interchangeable)

• Partial: For general use, thermometers should be immersed in the test solution up to the line printed on the thermometer.
• Total: For highest accuracy, the entire thermometer column needs to be immersed in the liquid to be measured. This gives the highest accuracy, but using a total immersion thermometer improperly will result in errors.
