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
