INDUSTRIAL THERMOMETER

• Standard Well & Lagging Well Option

• Mounting Options: Adjustable Angle

• Easy to Read Dual Scale

• 5 Temperature Ranges

• Aluminum or Molded Glass Fiber Case

Marsh Industrial Thermometers are designed for demanding applications. The large 9” scale permits easy reading
at longer distances. The glass-reinforced nylon case is lightweight yet rugged enough for demanding installations.
The adjustable stem can be locked into any position through a 180° arc. These thermometers are commonly used
on hot or chilled water lines in commercial/industrial buildings.

The Marsh Industrial Thermometers have a compact design that is well suited for limited space applications such
as diesel engines, steam turbines, reduction gears, pumps, condensers and pipelines.
