SJ Series

The Model SJ dial thermometer withstands vibrating conditions to give accurate temperature indication. Its liquid actuated temperature sensing system utilizes a spiral wound Bourdon tube that absorbs shock. Steady operation results, which combines with the 3 ½" dial size for ease of reading. The Model SJ is available in a variety of case styles and with a selection of temperature measurement ranges.
