DKG ONE-CF4 photoacoustic spectroscopy gas analyzer Introduction: Cleanrooms need to control the level of pollutants. Accurate, reliable, and low-cost AMC control of gaseous molecular pollutants in cleanrooms can significantly improve production capacity. The highly sensitive DKG ONE-CF4 can quickly detect pollutants in production environments. In addition, direct absorption detection can ensure long-term high stability due to its zero background property. The DKG ONE-CF4 analyzer is based on ultra sensitive cantilever beam enhanced photoacoustic spectroscopy detection technology, combined with quantum cascade laser (QCL) light source, and operates on the mid infrared basic spectral absorption peak of CF4. The combination of these two provides sufficient sensitivity to detect the smallest concentration of CF4 overflow without delay, while ensuring ultra-high levels of stability. The recalibration cycle can take several months or even years, greatly reducing the overall holding cost. characteristic: 1. Accurate, reliable, and low-cost clean room pollution control 2. Fast response time to capture sudden increases in concentration 3. Independent operating system with built-in gas exchange pump 4. No consumables or chemical reagents 5. Short path length and single point calibration can also achieve industry-leading dynamic range 6. Direct absorption measurement without drift 7. Long calibration interval (up to several years) 8. High selectivity, not affected by acetaldehyde and other VOCs interference Technical parameters: Response time: Depending on the channel integration time (C.I.T.) and gas replacement cycle, typically ranging from 3 seconds to 3 minutes Detection limit: 0.1ppb Dynamic Range: Typical Level 5 (100000 times detection limit) Repeatability: Measurement values less than 1% at standard concentrations under working conditions Accuracy: depends on the accuracy of the calibration concentration standard gas, typically 2-5% Temperature stability: No impact within the working temperature range Pressure stability: No impact within the pressure working range Chassis size: 48.4cm W x 13.9cm H x 44cm D (19.1 In W x 5.5 in H x 17.3 in D) Weight: Approximately 13kg Total gas production: 10-30ml Input voltage: 100-240VAC, 50-60 Hz Input power: 100-200 W (depending on specific requirements) Communication interfaces: Ethernet, USB
