Brief introduction: This instrument belongs to no spectral type infrared gas analyzer, its working principle is based on the certain choice of infrared gas absorption. Instrument using single light source, single tube every half air chamber and advanced detector, exquisite workmanship, analysis, high accuracy, good stability. The use of advanced digital processing technology, new LCD screen. Features: 1. The standard 19 cases (can be installed in the complete sets of equipment) 2. The large screen LCD display, full Chinese menu operation, and prompt function operation, the operation is simple and efficient 3. Manual/automatic zero/end point calibration, 4. The fully digital processing, more accurate and stable and reliable 5. Standard RS232 digital communication function, can be directly connected to a computer or DCS 6. The output of synchronization, isolation (4-20).two survivors/mA and (1-5) / 0/0.5 V signal is optional, by default (4-20 mA and (1-5) V, output current load 400 or less Ω, voltage output load Ω 250 or higher 7. A complete isolation of calibration, fault, alarm, such as range switching state of the output signal Technical parameters: Range: the minimum range of 0 ~ 50 PPM. The maximum range of 0 ~ 100% (according to the need to make sure) Repeatability: 1% or less (in distinguishing rate: constants: 0.01%, v/v or less trace: 1 PPM) Stability: zero drift plus or minus 1% or less F.S / 48 h Plus or minus 1% or less range drift F.S / 48 h Linear error: plus or minus 1% or less F.S The instrument response time: T90 acuities were 15 s Measured gas flow volume: 0.5 ~ 3 l/min Using the environment temperature: 0 ~ 40 ℃; Relative humidity: 90% or less Power: 220 v + / - 10%; 50 + / - 0.5 Hz 150 w Measured value output: 0 to 20 ma; 0 ~ 10 mv; 4 ~ 20 ma
