HT-1 ''Workhorse'' General Purpose Probe - designed for temperature measurement of liquids, gases and semi-solids. Plastic handle with straight 3'' stainless shaft. Not good for surface temperatures. Maximum temperature 400°C, Time constant 0.5 Seconds. 5 foot lead. Not isolated.
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.
