Marsh
Instruments Bimetal Thermometers combine the
benefits of economy and reliability for local mounted temperature
indication in the dual scale ranges from -50°F to 1000 (-40°C to 525°C).
Additional advantages offered by the Series "L" Bimetal
Thermometers include easy-to-read dual scale, fast speed of response,
and accurate temperature indication.
The hermetically sealed and ruggedly built case is resistant to shock,
vibration, dust and moisture. Corrosion resistance to most
chemicals is provided by the all welded type 304 stainless steel
construction.
The extremely responsive bimetal sensing element provides an accuracy to
within ±1% of scale. An external adjustment screw on the back of
the 3" and 5" case provides convenient reset and field
recalibration. Built-in over range protection is a standard
feature.
