1. Working Principle
Horizontal Tensile Testing Machine is a device used to test the tensile properties of materials in the horizontal direction. It usually consists of a sturdy base and a movable tensile fixture. The material sample is clamped between the tensile fixtures and the material is stretched by applying force. The testing machine can measure the tensile strength, breaking strength, elongation and other parameters of the material.

The calibration of VOC sensors, whether mutual calibration or calibration with standard instruments, is based on GB/T 14295-2008 Air Filter and the American Pollution Control Association recommended specification IEST-RP-CC014.2 Optical Particle Counter. The relevant provisions of calibration and characteristic calibration require the use of VOC gas sensor calibration chamber for calibration. The test method of the voc gas sensor calibration chamber is as follows.
Test equipment: Huanyi Instrument voc gas sensor calibration chamber
Calibration basis: GB/T 14295-2008 Air Filter, IEST-RP-CC014.2 Optical Particle Counter
