Eliminates Conversion Kits: Built-in tapered bulb and 1-1/4" x 18 swivel nut fitting
for SLIP-FIT Bimetal Thermometer interchange with existing industrial thermometer
style thermowells.

Replaceable Element Feature: (BIE & AIE Models): Easy to replace - just remove
the element and save the case, making changing the internal elements as easy as
replacing batteries in a flashlight. Range changes can be easily made. In some applications, used with a Union fitting, the case and stem will serve as a thermowell.

Adjustable or Fixed Back Connections: The All Angle (AI and AIE) Models offer
easy adjustment to any viewing angle. Back Connected (BI and BIE) Models are fixed
at the most common style connection.

Accurate: Consistent accuracy is achieved within 1% of full scale. Ambient temperature changes at the case will not affect accuracy.

Simple, Convenient Recalibration: Either reset gear or adjustable pointer feature
(Replaceable Element only), permits setting for zero calibration error at any desired
temperature within scale.

Easy-To-Read 3" or 5" Dial: Deep drawn, anti-parallax dial design. Dial can be
seen from a greater distance and from more angles than mercury-in-glass thermometers.Minimized reading errors from low-glare background with graduations
and pointer on the same surface level.

Hermetically Sealed Case: Securely sealed by quick-lock, cam-action bezel ring.
Heavy, heat resistant gasket seals out moisture, prevents icing and helix freeze-up.
