product description

The instrument has the characteristics of high measurement accuracy, wide range and simple operation. It is widely used for the determination of total nitrogen in surface water, groundwater, industrial wastewater and domestic sewage.

technical parameter

measuring range:  0 ~ 100mg / L indication error: ≤ ± 5%
repeatability: ≤ ± 3% temperature control system: room temperature ~ 180 ° C can be set, the total nitrogen digestion temperature is 125 ° C
digestion time:  30 minutes optical stability:  the absorbance drift within 20min is less than 0.002A
 Dimensions: Main unit: 340mm×250mm×130mm Digestion instrument: 355mm×260mm×135mm
weight: host 4kg, digestion instrument 5.5kg


With high performance, long life (100000 hours), high brightness light source imported from the United States, equipped with high stability optical system, with good accuracy and repeatability.

The digester adopts a 3.5-inch color touch screen with a resolution of 320x240, which is displayed in Chinese and English.

Simple and time-saving operation. The digestion colorimetry does not need to be changed.

With multi-point error free calibration, the zero error measurement of the set point is realized, which completely eliminates the error caused by the nonlinearity of the common digester in the market.

The digester has the function of timing reminder, automatic shutdown after digestion can be set, and the instrument has the function of secondary protection. When the temperature of digester exceeds 200 ℃, the instrument will cut off the power supply by itself to ensure the safety of digestion process

It can store 10 working curves and 999 historical records without losing power.

With USB interface, data can be transferred to the computer.

With printing function, it can print the test record or query the record immediately.
