该仪器是一种新型光电气检测仪,主要用于测量空气中二氧化碳浓度,其工作原理是利用CO2外光,将光信号转换成电信号,当空气中CO2浓度不同时,则信号大小不同,可显示出来。
该仪器最主要特点是成本低廉(仅为几百元),并且精度高,交、直流两用,便携式(仪器内部具有充电电线路),功耗小,操作简单,整机设计新颖,其光路和电路有创新性,
采用仪器主要技术指标如下:
(1)测量范围≤200-300ppm ;        
(2)工作误差≤5%;
(3)示值误差≤3% ;                
 (4)重复性误差≤3%;
(5)指示噪音(输出波动):≤0.5%  ;  
 (6) 干扰误差:水蒸气干扰≤1%;
(7)预热时间:≤15min;            
  (8)滞后时间:≤15秒;
(9)稳定性:零点漂移≤30/3h,量程(跨度)漂移≤4%/7h;
(10)功耗:≤1瓦(电流≤0.1A);
(11)供电:Ac220伏=20%,Dc伏=10%(蓄电池连续供电8小时);
(12)环境温度:0-40度  ;          
 (13)环境温度:≤90%;
(14)重量:2公斤;
农作物产量95%以上来自光合作用,即植物利用太阳光,将CO2和水合成为碳水化合物,而空气中CO2含量仅325ppm。因此,在温室和塑料大棚空气中增施 CO2 气可大幅度增加蔬菜产量,如西红柿可增产几倍,此项技术几年前曾获国家科技进步二等奖,不同植物对空气中CO2 的浓度有不同最佳值和限额,若CO2 浓度超过限额,植物反而减产,这就需要检测空气中CO2 浓度并可根据不同植物和不同光照强度控制浓度,使之达到最佳值,进一步增增增收,可是国内外现有的红外气体分析仪均为双电路系统,锁相放大电路,优点是精度高,缺点是结构复杂,使用不便,尤其是价格昂贵(至少万元),没有用于温室或塑料大棚中并针对我国国情适合农民使用的CO2 检测仪。
应用范围:
该仪器具有广泛的适用性,虽然它主要为温室和塑料大棚中蔬菜生产设计的,但也可用于许多方面。如温室中花卉生产;蔬菜与水量储存和保鲜;环境保护与检测;医疗和卫生防疫(如宾馆、商店、医院、影剧院、歌舞厅、车厢、机舱和利用人防等地下公共场所),并可用于军事领域。下面仅就应用于温室和塑料大棚蔬菜生产进行分析。
效益分析:
下面仅就应用于山东省某县(全国蔬菜生产基地)温室进行分析。由于目前没有仪器检测CO2 浓度,只能凭经验估算每个大棚中CO2 施气量(约1000ppm),且宜少不宜多,以免减产。
这浓度并未达到蔬菜所需最佳值,因此使用CO2 检测仪检测后可以增加CO2 气浓度,进一步增产增收,该县有19万个大棚,使用CO2 检测仪后蔬菜至少再增产15%,每个收获季节亩产平均约8000斤,每个大棚约一亩地,每年收1茬,则全县每年可增产8000×2×15%×190000=4.56亿斤。若每斤平均卖0.8元,则可增收4.56亿×0.8=3.65亿元。每个大棚每年增收8000×2×15%×0.8=1920元,所以农民能买得起。
