Description
JRZ10 Building Material Combustion Calorific Value Determination Apparatus
1. Product Overview
The JRZ10 Building Material Combustion Calorific Value Determination Apparatus is a fully automated constant-temperature oxygen bomb calorimeter integrated with professional microcomputer control system. Controlled by dedicated Windows test software, it automatically completes full testing, data acquisition and result calculation.
This lab instrument accurately measures the gross heat of combustion (total calorific value) of combustible samples, covering building materials, coal, petroleum products, chemicals, timber, food and explosive materials. It is core equipment for fire hazard classification of construction materials, raw material quality inspection, fuel energy detection and material combustion performance research, widely used in third-party fire certification labs, construction material factories, energy testing institutions and university research labs.
