●The use of high brightness, long life cold light source, as well as high stability narrowband interference optical system, the instrument stability, high reproducibility.
●Digestion and host are independent instrument, does not affect the stability of the optical system.
●Digestion temperature PID automatic temperature control, timing and high accuracy.
●Digestion temperature and time can be infinitely set to be used for other purposes.
●Digestion, colorimetric cuvette with the same digestion tube, its strength, high hardness, can be used repeatedly.
●can each save COD, ammonia nitrogen, total phosphorus and total nitrogen standard curve 10 and 99 measured values, power is not lost.
●print function: test records can be printed or query records to print immediately.
●with a USB interface data upload function, the instrument can be stored in the data uploaded to a computer to save the recording or editing print.
●Has a factory recovery curve to restore accidentally deleted curve operation.
●LCD large-screen LCD, long life and low failure rate, operating english menu
