由中国科学院上海冶金研究所研制,并由上海嘉定学联仪表厂试制的小型、便携、低功耗的氧、二氧化碳气体分析仪,最近在上海嘉定通过鉴定。该仪器测量速度快、重复性好、精度高、结构紧凑、体积小(190×100×70毫米)、重量轻(1.2公斤)、采样气体少和功耗低。主要技术指标是:①精度:±3%(满量程);②响应时间:小于40秒;③重复性:0.1%(氧)、0.2%(二氧化碳);④环境温度:5～40℃可自动补偿;⑤电源:5~#电池9节或用交流电,功耗约0.3瓦;⑥采样方式:手握
The small, portable, low-power oxygen and carbon dioxide gas analyzer, developed by Shanghai Institute of Metallurgy, Chinese Academy of Sciences and trial-produced by Shanghai Jiading Shenshi Instrument Factory, recently passed the appraisal in Shanghai Jiading. The instrument has high measurement speed, good repeatability, high precision, compact structure, small size (190 × 100 × 70 mm), light weight (1.2 kg), less sampling gas and low power consumption. The main technical indicators are: ① Accuracy: ± 3% (full scale); ② Response time: less than 40 seconds; ③ Repeatability: 0.1% (oxygen), 0.2% (carbon dioxide); ④ Ambient temperature: Compensation; ⑤ Power: 5 ~ # 9 batteries or AC, power consumption of about 0.3 watts; ⑥ Sampling methods: Hand
