â– SBA-5 series introduction:
PP Systems is a world-renowned company specializing in the development and development of plant physiology and ecological science instruments and high quality infrared CO2/H2O analyzers. Dr. Keith J Parkinson, the founder of the company, has more than 30 years of experience in producing high quality infrared CO2/H2O analyzers. He designed the world's first open gas path photosynthetic system, which is widely used in many international photosynthetic systems. Adopted, the core high-quality infrared CO2/H2O analyzer provides open source development ports for the majority of companies. After the founding of PP Systems in 1984, the company has a number of patented technologies such as auto-zeroing and differential balancing of the world's unique infrared analyzers to produce a world of high-quality infrared CO2/H2O analyzers.
The two technologies of automatic zero adjustment and differential balance ensure data accuracy and avoid human error. In the measurement, once the instrument detects that the difference exceeds the specification, it will automatically zero and balance immediately, without human intervention, and ensure data consistency.
At present, the company has CIRAS series ultra-high precision CO2/H2O analyzer, EGM series portable high-precision CO2/H2O analyzer, WMA series laboratory high-precision CO2/H2O analyzer, SBA series high-precision open source CO2/H2O analyzer.
Measurement parameters (function): Accurate measurement of CO2 concentration, temperature, humidity, oxygen, etc. in the environment or container
Main applications: environmental gas monitoring, indoor environmental control, atmospheric research, growth chamber, biodegradation, CO2 storage and escape, animal and plant respiration, fruit and vegetable storage, brewery, medical equipment, CO2 leakage, indoor air quality and safety, industrial monitoring, Oceanography and other research
â– SBA-5 performance:
â—‹ Measurement method: Microcomputer controlled linear non-dispersive infrared gas absorption meter
â—‹CO2 measurement range: 0-1000ppm (accuracy 0.1%)
â—‹ Pressure compensation range: 80-115kPa
â—‹ Accuracy: 0.1% within the calibration range, the actual accuracy is affected by the accuracy of the calibration gas
â—‹ Linearity: <1% within the range
â—‹ Accuracy: It can automatically zero at specified intervals to correct drift caused by sample chamber contamination, light source and detector aging, preamplifier gain change
