— Quality —
  • "Product quality is the lifeline of enterprise development." Hengxiang Technology attaches great importance to product safety requirements, quality requirements, and service requirements. The company has successively introduced thermal conductivity meters, Mooney viscosity meters, oxygen index meters, and smoke density meters to ensure products The superior performance.

    The constant temperature and humidity test chamber is preset in the constant temperature and humidity chamber to adjust the temperature and humidity of the sample to meet the test requirements.

    Oxygen index meter

    The oxygen concentration is calculated by adjusting the oxygen and nitrogen flowmeters respectively. In general, the higher the measured oxygen index, the better the fire resistance of the material.

    Smoke density tester
