China's first autonomy pH tester came out in Beijing

Launched by Beijing Changan (Group) Henderson Electronics Co., Ltd., the first domestic HYW type upper digestive tract pH dynamic tester with independent intellectual property rights for gastric and esophageal reflux disease was launched in Beijing for 8 years. .

It is understood that the instrument can continuously measure the pH value in the stomach and esophagus for 24 hours, and is recorded and stored by the microprocessor through analog-to-digital conversion, and then analyzed and processed by computer system to print various statistical tables, histograms, trend graphs, etc. Based on the clinical diagnosis, the objectification and quantification of long-term continuous measurement of pH value in the body are realized.

The instrument has been developed to provide effective clinical diagnosis and clinical and pathological and physiological research on difficult diseases such as reflux respiratory disease and non-cardiac chest pain and throat diseases caused by gastric and esophageal reflux disease. Tools and means. In particular, it provides a reliable objective diagnosis basis for patients with "stomach and esophageal reflux symptoms, and under the endoscope, the esophageal mucosa is normal".

Domestic gaps in this field.

The Small Graphite Crucible is one type Graphite Crucible with very small capacity. Generally, it is used in the lab for analysis. Clients will put the powder in the small graphite crucible, and put it in the high temperature furnace. We always adopt the high pure graphite material for the small graphite crucible and polish the surface inside and outside. There will no metal liquid and any other smelting residue. We can also design the graphite cover for the graphite crucible. Sometimes, our clients also choose the fine grain type graphite material. But this type is not durable for such small size. Clients choose this just for one time use.
