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 a probe. When probe is used for continuous measurements, max. temp. should be reduced by 25 % unless specified.
