Introduction: The calibration accuracy is high, it is easy to carry, and can meet the flow calibration of the soot sampling instrument. It is widely used in measurement verification, environmental protection monitoring, labor insurance and health, scientific research institutes and other occasions that require gas flow calibration. Executive standard JJG680-2007 "Verification Regulations for Smoke Sampler" Features: 1. The temperature and atmospheric pressure can be automatically measured or manually input 2. Large-capacity data storage and query, with digital interface, can be connected to an external printer for printing or connected to a computer for data communication 3. Automatically convert the standard flow rate and read directly 4. The flow rate in multiple states can be automatically converted and displayed at the same time 5. AC and DC dual purpose, built-in high-energy lithium battery, long working time 6. With software parameter calibration function and user password protection function 7. Chinese dot matrix LCD display, rich interface display 8. Automatic fault detection protection 9. Attached with the calibration certificate of China Metrology Research Institute to ensure measurement accuracy
