Bi-Metal Thermometers

Bi-metal thermometers use two bonded metal strips with different expansion rates to provide accurate, reliable temperature measurement. As temperature changes, the metals expand differently, causing a calibrated mechanical dial to indicate precise temperature values. Ideal for industrial environments, these robust instruments withstand harsh conditions such as extreme temperatures, vibration, and corrosive atmospheres. Bi-metal thermometers commonly measure temperature in HVAC systems, boilers, heat exchangers, piping systems, and industrial processes including chemical, petrochemical, pharmaceutical, and food industries. Simple installation, maintenance-free design, durability, and visual clarity ensure consistent operational reliability and accurate readings critical for process control and safety.
