POLYTEF
TRADER
Polytef Trader is the leading thermocouple wires and cables supplier in Uttarakhand, offering high-quality thermocouple and compensating cables for precision temperature measurement. Our wires are trusted by process industries, laboratories, and manufacturing sectors across India for accurate and reliable temperature sensing.
Thermocouple wires are specialized cables made from two different metal alloys that generate a voltage proportional to temperature difference. This phenomenon, known as the Seebeck effect, enables accurate temperature measurement across a wide range of industrial applications.
As a trusted thermocouple wires supplier in Uttarakhand, Polytef Trader offers a comprehensive range including thermocouple grade wires, extension wires, and compensating cables in all standard types (J, K, T, E, N, R, S, B) with various insulation options to meet diverse industrial requirements.
Complete range of thermocouple wires for all temperature sensing applications
Most popular general-purpose thermocouple for wide temperature range applications.
Popular for vacuum and inert atmosphere applications with good sensitivity.
Best for cryogenic and low-temperature applications with high accuracy.
Highest EMF output per degree, ideal for cryogenic to moderate temperatures.
Enhanced stability and oxidation resistance, alternative to Type K at high temps.
Platinum-based thermocouples for very high temperature and precision applications.
Different grades for different applications
Used at the sensing junction where actual temperature measurement occurs. Highest accuracy and purity.
Same alloy composition as thermocouple grade but with relaxed tolerances. Used to extend thermocouple circuit.
Different alloy that matches EMF characteristics. Cost-effective alternative for long cable runs.
