Bimetallic Thermometer for Industrial Pipeline
-- Steady & Reliable Manufacturer --
Product Overview
Our Industrial Bimetallic Thermometers provide dependable local temperature indication across a broad range from −50°C to +500°C, without any electrical power source. The sensing element is a precision-wound bimetallic coil that responds to temperature by rotating a shaft connected directly to the pointer. Housed in a robust stainless steel case with a large, easy-to-read dial, these thermometers are the standard choice for steam lines, heat exchangers, HVAC systems, and chemical process piping where simple, low-cost, maintenance-free temperature monitoring is required. The adjustable-angle head option allows the dial to be oriented for optimal visibility regardless of installation position.
