 Purpose and use of 
 ZDR Series microcomputer solid carbon dioxide (CO2) measurement and control instrument is a health epidemic prevention, environmental protection, scientific research departments in the CO2 concentration measurement and control environment, special equipment. It on hotels, restaurants, discos, shops, air defense fortifications, cars, cargo hold, storage and other public places in the CO2 concentration in the air monitoring and control. Can also be used for agricultural research, plant photosynthesis in the field measurements, CO2 fertilization, vegetables, fruits, grain storage CO2 monitoring and control. The instrument temperature is -5 ℃ ~ +45 ℃, relative humidity is not 85% RH. The environment does not have a corrosive gas, 

 Features 
 FIGARO adopting international advanced solid CO2 analyzer movement, the machine has no moving parts. By a microcomputer control automatic equipment, the operation does not adjust zero and full scale. Zero and full-scale differential drift does not exceed 5 years. Figures show CO2 concentrations, 220V50HZ electricity supply. 2 hours after the warm-boot, small size, light weight, high precision and long life. Zero adjustment without alkali asbestos, diffusion sampling, sampling without electric pump with power-saving features. 
 The test controller can be set by the user of the CO2 concentration, CO2 concentration in the external automatic control, simple operation, easy to use. 
 Detection and control built-in smart chip, LED display, the use of international brands of sensors, microprocessors, and data records to remain solid, long-distance communication interface.
