NOTES

1. Minimum recommended insertion length (“u” dimension) in liquids is 4 inches and in gases is 6 inches for standard 3⁄8 × 3˝ bulb.

2. Thermowells must be used on any application where the bulb of the thermometer may be exposed to pressure, corrosive fluids, or velocity.
Additionally, the use of a thermowell permits instrument interchangeability or recalibration without shutting down the process.

All specifications are subject to change without notice.

All sales subject to standard terms and conditions.
