QUALITY GUARANTEE

SICC can supply type N thermocouple alloy wires meet the accuracy standard IEC60584 and ASTM E230, The advanced melting skills combined controls the chemical composition to achieve the highest quality products , our produce base has the capacity of 900 tons annual with 35000 square meters that can meet your comprehensive requirements. whatever the bright annealed or oxidized conditions,all thermocouple materials are calibrated at our lab ,this includes the testing of EMF, chemical composition,physical and thermoelectric properties before shipment.


SICC provides calibration results for all bare thermocouple wires with each shipment, including EMF values, accuracy, batch number, raw materials chemistry, lab environment condition,etc, each order has only one job number for tracement, Calibration capability is available up to 1000C on suitable thermocouple types.

Our lab routinely calibrates at the following fixed points:100C,200C,400C,600C,800C for type N thermocouple materials,we work continuously to reduce the measurement uncertainty at each calibration temperature and new estimates are made every six months to ten months,ensuring any deviations are identified early so that results generated by the lab remain consistent and accurate.

    Nickel chrome wire

    Nickel chrome wire is a kind of non-magnetic alloy of nickel and chromium, it is widely used in heating elements. The maximum operation temperature of the heating elements is related to the wire diameter, it is better to choose thicker wires, the corrosive atmospheres also have a considerable relationship with the maximum operation temperature. The surface temperature is about 100C higher than the inner normally, when the operation temperature exceeds the limit, the oxidation of heating elements itself is accelerated, the heat resistance will be reduced, which is easily deformed,collapsed and even appreas to be broken, thereby shortening the service life.

    Mineral insulated thermocouple cable

    Mineral insulated thermocouple cable is used to insulate thermocouple wires from one another and from the metal sheath that surrounds them. MIMS Cable has two (or four when duplex) thermocouple wires running down the middle of the tube. The tube is then filled with magnesium oxide powder and compacted to ensure the wires are properly insulated and separated. Mineral insulated cable helps to protect the thermocouple wire from corrosion and electrical interference.
