Please note the following definitions in the product descriptions below:
Time Constant is defined as the time required to reach 63% of final temperature in liquid. An accurate reading is obtained when the reading stops changing, typically 5-10 time constants.
Maximum Temperature refers to intermittent use of probe. When probe is used for continuous measurements, maximum temperature should be reduced by 25% unless specified.
