Production of soil respiration analyzer

　　Soil respiration meterKey Features:

● Intuitive display: The Chinese LCD screen has a 160 × 256 dot matrix, which is easy to operate and has a clear interface.

Data storage: Large capacity SD cards are used to store data, with a large storage capacity and easy export.

Data collection: It can simultaneously collect indicators such as CO2 concentration, soil temperature, air temperature, air humidity, photosynthetically active radiation intensity, gas flow rate, etc. The stability, accuracy, importance, and time response of the measurement are all very good.

● Easy to use: small size, light weight, portable, single person operation, free movement, clear air and circuit connections.

● Suitable for general use: Users can choose different volumes of breathing chambers or select breathing chambers for other purposes, which can be widely used for measuring the respiration of soil, fruits and vegetables, seeds, plants, etc.

● Convenient power supply: Equipped with standardized maintenance free lithium batteries, it can be used for more than 10 hours on a single charge, and can also be powered by both AC and DC methods.

● Instrument protection: Adopting a miniature electronic flowmeter with air path blockage warning protection function.
