Installation and Maintenance Instructions
BI-METAL THERMOMETERS
CAUTION
1. Thermometers can be rendered inaccurate during shipment despite care
taken in packaging. To assure the accuracy to which the thermometer was
manufactured, it should be checked before use. When installing the
thermometer into a threaded connection, always tighten with a wrench on
the hex nut.
2. Never use the head of the thermometer for tightening.
3. Bi-Metal thermometers should be installed in thermowells on all pressure
and velocity applications to protect the stem from corrosion and/or
damage.
CALIBRATING INSTRUCTIONS
1. A very accurate master thermometer should be used for calibration.
2. Immerse Trerice thermometer together with a master thermometer into an
agitated liquid for at least three minutes. Compare thermometers.
IMPORTANT – For most accurate reading, at least three inches of the
stem must be immersed in the liquid. The master thermometer
should also be immersed to the same depth.
3. A slotted hex head calibrating screw is provided on the back of the
thermometer case.
4. With a ¼ inch wrench or screw driver, turn the screw until the pointer
reads the exact temperature.
NOTE: Series B83100 & B82200Y cannot be recalibrated.
