Industrial Thermometer

The Industrial Thermometer from Marsh Instruments offers high-performance monitoring in temperature ranges to +300°F (+150°C) in a compact design. The large 9″ dial scale of the Industrial Thermometer permits easy reading at extended distances. The thermometers feature a glass-reinforced nylon case that is lightweight, yet rugged enough to withstand harsh environments. The adjustable stem can be locked into any position through a 180° arc.  The Industrial Thermometer is commonly used on hot or chilled water lines in commercial/industrial buildings. Their compact design is also especially well-suited for use in space constrained applications such as those typically encountered in diesel engines, steam turbines, reduction gears, pumps, condensers and pipelines.
