NiCr-CuNi Type E Constantan Thermocouple Wire Versatile and Accurate for Industrial
NiCr-CuNi Type E Thermocouple Wire is a highly accurate thermocouple material known for its excellent thermoelectric properties and high sensitivity. It consists of a positive leg made of Nickel-Chromium alloy (NiCr) and a negative leg made of Copper-Nickel alloy (CuNi), also known as Constantan. Type E thermocouples are ideal for applications requiring precise temperature measurements in a wide range of environments.
NiCr-CuNi Type E (Constantan) Thermocouple Wire is a highly sensitive and accurate thermocouple material suitable for cryogenic and moderate high-temperature applications. Its superior thermoelectric output, non-magnetic nature, and excellent performance in clean environments make it ideal for precise temperature measurement in scientific, industrial, and medical applications.

Produces the highest thermoelectric output (Seebeck coefficient) of all standard thermocouple types, approximately 68 µV/°C, making it highly sensitive to temperature changes.
Operates effectively in temperatures from -270°C to 870°C (-454°F to 1600°F).
Particularly effective for cryogenic and moderate high-temperature applications.
Provides precise temperature readings with standard tolerances of ±1.7°C or ±0.5% of the measured temperature.
Resistant to oxidation in clean and dry environments, but not suitable for reducing or sulfurous atmospheres.
The Constantan (CuNi) leg provides stability in various conditions.
Positive Leg (NiCr): Typically 90% Nickel and 10% Chromium.
Negative Leg (CuNi/Constantan): Typically 55% Copper and 45% Nickel.
Stable thermoelectric behavior ensures consistent readings over extended periods.
Ideal for low-voltage signal measurement.
