Zedeyes 431 Flat Glass  Thermometer

The Zedeyes 431 flat glass thermometer is engineered for exceptional vibration resistance, making it an essential instrument for marine vessels, industrial pipelines, power generators, and heavy-duty HVAC installations. Featuring a flat V-shaped aluminum case and a precision spirit-filled glass capillary, it provides steady, accurate, and glare-free temperature readings even in environments subjected to severe mechanical oscillation and engine vibration.

Protected by a durable brass-colored aluminum housing and a solid brass thermowell, the Zedeyes 431 offers a completely power-free, maintenance-free temperature monitoring solution built to withstand harsh marine and industrial conditions.

Key Features & Benefits

• Vibration-Resistant Construction: Specifically designed to absorb line vibration and mechanical shocks commonly found in marine engine rooms and pumping stations.

• Power-Free Thermal Indication: Operates strictly on liquid thermal expansion, delivering continuous, reliable readings without electrical wiring or battery replacement.

• Straight & 90° Angle Mounting Configurations: Offered in straight (Model 431L) and 90° right-angle (Model 431B) styles to fit any pipeline orientation or tight mounting location.

• Corrosion-Resistant Housing & Thermowell: Built with a protective brass-colored V-shaped aluminum body and a matching threaded brass thermowell for efficient thermal transfer and longevity.

• Wide Insertion Options: Available in insertion lengths ranging from 30 mm up to 250 mm to ensure proper immersion depths in varying pipe diameters and vessels.

Primary Applications

• Marine & Shipbuilding: Engine cooling lines, fuel preheaters, exhaust manifolds, and marine ballast systems.

• Industrial Pipelines: High-vibration fluid transport lines, oil lines, and steam utility piping.

• HVAC & District Energy: Commercial heating headers, chillers, and large-scale boiler loops.

• Heavy Machinery & Power Skids: Generator sets, large hydraulic units, and compressor stations.
