In the process of product development and quality control, simulating product performance under extreme environmental conditions is a crucial task. Thermal shock test is a common method used to evaluate the performance stability of materials or products under rapid temperature changes. As an advanced testing equipment, the Three box-type Thermal Shock Test Chamber has been widely used in aerospace, electronics, automobile manufacturing and other industries.

Drug stability test chambers are widely used in pharmaceutical and other scientific research institutions for drug stability test operations. They are usually composed of a chamber, a refrigeration system, etc. There are many brands and models of drug stability test chambers on the market. To choose a suitable drug stability test chamber, you need to master some key points for selecting drug stability test chambers. Next, let me show you the common selection methods:

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
