What is the oxygen index test?Oxygen concentration values are known as the Oxygen Index (OI) or, historically, the Limiting Oxygen Index (LOI). The oxygen concentration is measured using a paramagnetic oxygen analyzer and is controlled by varying the relative flow of oxygen and nitrogen through a ve

In November, our customer from a lab in the USA purchased our GD-ISO1182 Building Material Non-Combustibility Tester.

In September, a customer from Norway purchased our GD-1716 Bomb Calorimeter for building material heat of combustion test. We have completed production in late September.

Bomb calorimeter - The calorific value of the sample is measured.
