GT-1 Air and Gas Probe - 24'' #304 stainless steel shaft. Wooden Handle. For instant readings of temperature gradients in environmental chambers, freezer boxes, etc. Diameter is .3/16'' diameter. Immersible. Maximum temperature 200°C, Time constant 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.
