Caltech India is the leading manufacturer and supplier of CES 296 Magnetic Surface Thermometer. The Magnetic Surface Temperature Gauge is a high-accuracy, easy-to-use temperature measuring device designed for monitoring the surface temperature of ferrous metal equipment. It is built with quality materials, using the strongest magnet ever designed for a surface thermometer. It is also known as Magnetic Dial Thermometer and Surface-Mount Magnetic Thermometer.
It is designed for applications such as surface temperature measurement for hospitals, IVF labs, rail fabrication, hot plates, weld preheats, annealing, foundry boxes, annealing ovens, furnaces, motors, generators, engines, ovens, bearings, dies, molds platens, hotplates, griddles, boilers, tanks, drums or any application where metal surfaces temperature needs to be monitored
It is equipped with a strong built-in magnet, which allows the thermometer to attach firmly to ferrous surfaces such as pipes, boilers, tanks, ducts, radiators, HVAC units, industrial machinery, and other metal surfaces, providing fast, reliable and continuous temperature monitoring.
The thermometer typically consists of a bi-metallic sensing element, a durable dial indicator, and a strong permanent magnet that ensures stable attachment even in demanding working environments. When placed on a hot or cold metal surface, the bi-metallic strip inside reacts to temperature changes by expanding or contracting, which in turn moves the pointer on the dial to display the real-time temperature.
Magnetic Surface Temperature Indicator are valued for their robust construction, fast response, and reliable readings over a broad temperature range. Because they do not require drilling, wiring, or external power, they offer a simple and cost-effective solution for surface-temperature measurement.
In industries where efficiency and safety are critical, Magnetic Surface Thermometers help operators maintain optimum operating conditions and identify potential issues early. It ensures safe operation by helping users detect overheating, energy loss, and irregular temperature variations. Their portability and ease of installation make them ideal for field technicians, service engineers, and maintenance professionals across manufacturing, automotive, chemical, power generation, food processing, and HVAC sectors.
