Features: - 19" standard machine case, easy installation, IP65/IP54 defense degree - High stability, low excursion range, high precision, high ingenuity - Strong anti-jamming capability, high identification capability, short delay time - Multi-functions, constant temperature, linearization, shift between measure extensions, maximum alarming - Small size, light weight, convenient operation, easy maintenance Fields of application The instrument can on-line serial analyze the content of CO, CO2 and CH4 etc. Respectively, or the measure the content of several sample gases at the same time, which are applied in the power generation station, petroleum chemistry, concrete manufacture, metallurgy, chemical fertilizer, air pollution inspection, air analysis, constructing material etc. The advantage of the DI101 Dazhi infrared gas analysis instrument use the Dazhi patented sensor which have twice refrigeration to guarantee sensor keeping in constant temperature, which make our instrument enjoy a high precision, and high stability, reliability and ingenuity, at same time, the patented sensor cut our cost and make our instrument more competitive comparing our competitors. The capability Measure extension: One instrument can measure two measuring range which the rate of the two ranges should not bigger than 20:1. Linear output: All measure extension is linear outputted. Display: Display by LCD, multi-language operation menu, can show content and time at the same time, and can auto store the information when meet abrupt power off, and check the information and store them at any time, it has multi-function and can be operated easily. High point alarm: It has maximum and minimum alarming point, which can be set by the customers freely. Output signal: It has three kinds of output way that is 0~10mv, 0~20mv, 4~20mv which can be selected by out customers. The main technical parameter: Measure range: 0-100ppm or 0-100% depending on the choice of the customer Target gas: CO, CO2, CH4, NH3, SO2 etc. Linear error degree: +-0.5% FS Zero excursion: <=+-1% FS/week Measure extension excursion: <=+-1% FS/week Reaction time: Normal percent T90 <5S, ppm T90 <10S Output: Signal: 0-10mv, 0-20mA, 4-20mA depending on the c
