BT-1 General Purpose Probe - Probably our best general purpose probe designed for temperature measurement of solids, liquids, gases and semi-solids. Welded stainless-stell shaft, plastic handle. Tip is .028'' diameter bent at right angle to probe to facilitate accurate surface measurements. Immersible. Maximum temperature 240°C, Time constant 0.15 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.
