BDFIA-200 Portable Flow Injection Analyzer Introduction: The BDFIA-200 portable fully automatic flow injection analyzer is a miniaturized and integrated design of laboratory instruments, which can be used for temporary on-site testing. The instrument adopts a suitcase design, which is convenient for users to carry. It can be used for on-site testing or emergency monitoring of drinking water, surface water, groundwater, sewage, and so on. characteristic: 1. Support the determination of multiple parameters, including volatile phenols, (total) cyanides, anionic surfactants, total phosphorus, total nitrogen, ammonia nitrogen, nitrate/nitrite, hexavalent chromium, etc; 2. The instrument adopts an integrated overall design, with each module embedded with an automatic sampler, peristaltic pump, chemical analysis flow path, dual beam detector, temperature controller and control circuit matched with the chemical analysis flow path, and built-in online automatic dilution device; 3. Built in standard curve, the concentration can be directly calculated based on the standard curve after sample injection, which is convenient and fast; 4. It can achieve an automatic dilution factor of 20 for the sample, and the automatic dilution standard curve can automatically configure 6 concentration points (including concentration zero), with a correlation coefficient r>0.9995; 5. Equipped with a built-in cleaning solenoid valve, it automatically cleans the internal pipeline after testing the sample to avoid cross contamination between samples; 6. Equipped with an intelligent operating system and user-friendly operation prompts, it enables continuous measurement of multiple samples and shortens the analysis time for a single sample; 7. Equipped with a suitcase and a portable power bank, it is easy to carry and suitable for on-site monitoring of water quality in environmental pollution incidents; 8. Built in 42 bit automatic sampler for fully automatic monitoring; 9. Equipped with a vehicle mounted device and a mobile power supply, it is convenient to set up monitoring points along the river or around the lake, suitable for emergency detection or daily monitoring of water system environmental emergencies; 10. Adopting earthquake resistant design, not limited by terrain and climate; Equipped with windproof design, not affected by external airflow interference; Equipped with a light avoidance system, outdoor work is not affected by external light sources.
