Review on hand2mind High-Range, Dual-Scale, Mercury-Free, Safety Thermometers: Ideal for Indoor Science Activities (Pack of 10) by Jay Blo

Revainrating 1 out of 5

Soften and heat to the boiling point of water.

Not reliable at temperatures above 90 degrees Celsius. I used them for a home lab for my chemistry students to measure the temperature of boiling water. The students brought them back with their ends warped from the heat. That's terrible, because thermometers have a mark of up to 120 degrees Celsius.

Pros
  • Finally bought
Cons
  • Expensive insurance
