This product is the use of sealed catalytic digestion, and then colorimetric measurements.
The instrument uses advanced , narrowband interference technology and microcomputer
automatic processing of data, direct display. The instrument is widely used in environmental monitoring,
wastewater treatment and universities, research institutes and other departments.
Technical Parameter Measurement Range: (over dilution assay) COD: 5 ~ 2000mg / L Ammonia: 0.02 ~ 25mg / L Total Phosphorus: 0.00 ~ 10mg / L Indication error: COD: ≤ ± 5% Ammonia: ≤ ± 3% (F.S) Total Phosphorus: ≤ ± 5% (F.S) Repeatability: ≤ 3% Resistance to chloride interference: ≤ 2000mg / L (COD measurement) Temperature control system: room temperature ~ 180 ℃ can be set, COD digestion temperature of 165 ℃, total phosphorus digestion temperature of 120 ℃. Temperature control accuracy: ± 0.5 ℃ Temperature control time: 1 ~ 999min adjustable Digestion time: COD is 15min, total phosphorus is 30 min Optical stability: Instrument absorbance values drift less than 0.002A within 20min Batch capacity: 16 water samples Dimensions: COD total phosphorus ammonia analyzer 340mm × 250mm × 130mm Digestion device (DIS-16 type) 216mm × 320mm × 146mm Weight: host 6kg, digestion device 4kg Power consumption: <500W Normal conditions of use: ⑴ Ambient temperature: 5 ~ 40 ℃ ⑵ Relative humidity: ≤ 85% ⑶ Power supply: AC (220 ± 22) V; (50 ± 0.5) Hz ⑷ no significant vibration and electromagnetic interference, avoid direct sunlight. Feature ●Analyzer separated with digestion, without affecting the stability of the optical system. ●Analyzer is cold light, narrowband interference optical system, good optical stability. ●High temperature digestion PID automatic temperature control, timing accuracy. ●Simple operating and saving time, Digestion colorimetric no need to change tube. ●Digestion temperature and time can be infinitely set to be used for other purposes. ●Can each save COD, ammonia nitrogen and total phosphorus standard curve 10 and 99 measured values, power is not lost. ●LCD large-screen LCD for easy and intuitive operation. ●Has a factory recovery curve to restore accidentally deleted curve operation. ●Has a print function: recording test print or query records printed immediately. ●USB interface can be connected to a computer.
