100mm – Gas Filled Thermometer – Back Stem

Heavy-Duty 100mm Gas-Filled Dial Thermometer – Back Stem Entry

Achieve highly reliable, clear, and instant thermal readouts with our commercial-grade 100mm Gas-Filled Back Stem Thermometer. Engineered for direct insertion into process lines, tanks, ventilation ducts, and mechanical plant rooms, this instrument utilizes a sophisticated inert gas thermal system. This provides superior linearity and speed of response compared to old-fashioned bimetal alternatives.

The distinct Back Stem (rear entry) profile allows for clean, flush installation onto front panels, manifolds, or pipe headers, positioning the massive 100mm dial squarely facing the operative for optimal visibility.

Fully Configurable for Your System

• To suit diverse mechanical specifications, this product is available to customize in your choice of specialized measurement spans and insertion depths:
• The 0°C to 120°C range is ideal for LPHW (Low Pressure Hot Water) systems, boiler loops, heating networks, and condensate lines.
• The -20°C to +40°C range serves as the perfect diagnostic tool for chilled water networks, refrigeration plant equipment, and environmental conditioning.

Key Benefits & Structural Features

• Rapid Inert Gas Actuation: Delivers highly accurate pointer movement with zero lag, unaffected by ambient casing temperature changes.
• Large 100mm Dial Face: Features stark black markings over a clean white contrast background, allowing engineers to check system states from a distance.
• Dual Stem Profiles: Pick between a 63mm or 100mm immersion stem to hit the absolute center-stream of your process flow, reducing thermal gradient errors.
• Robust Mechanical Casing: Built to withstand the vibrating, heavy-use environment of active commercial mechanical plant rooms.
