Electrlcallsolatlon Except as noted, sensing elements and lead wires are electrically isolated from the outer probe surfaces. To provide maximum safety for medical and biomedical applications, however, the probe should be used with isolated instruments. Time Constant Time required to indicate 63% of the difference between two sequentially impressed temperatures. Derived from measurements in water at 3 ft/sec, except 405, which is measured in moving air at 3 ft/sec at 0% RH. Approximately five time constants are required for a probe to read 99% of total temperature change. Note: Stable glass bead sensors are available in other configurations on special order, please contact factory.
