| Thermocouples and TC Ts | ||
 | High temperature, three point thermocouple, 24" long by 1/8" or 1/16" OD; K type, inconel shieth. Measure temperature at three points inside a reactor. Temperature is measured at tip, 4" up, and 8" up. |
$600. |
 | 3 point thermocouple in a "Thermocouple T". High temperature, three point, K-type thermocouple; 1/8" OD inconel shieth, as above, threded from the side through a thermocouple "T". Allows flow to enter at pressure without interfering with the temperature measurements, and allows catalyst to be added and removed easily without interfering with thermocouple. Temperature is measured at tip, 4" up, and 8" up. |
