★ Digestion time: 10 minutes
★ Monochromatic wavelength: 610nm
★ Optical stability: absorbance within the 20mim drift of less than 0.002A
★ Batch weight: 20 water samples/second
★ Maximum power: 400W
★ Dimension: host: 210x280x190mm (length x width x height)
Digestion: the 200x240x190mm (length x width x height)
Characteristics of the instrument:
1, the use of cold, monochromatic light source, optics excellent stability, will not be affected by a variety of disturbances.
2, the use of PID control digestion temperature, high precision temperature control.
3, large screen (320x240) LCD display, all operating under the same screen press menu to realize.
4, high-temperature digestion and colorimetric (including host) separation of the two parts, makes the effect of temperature on optical parts to a minimum.
5, high efficiency and digestion and 20 water samples at a time, each batch of samples measure time is only about 20 minutes.
6, cell each time you remove the cleaning, clean can be avoided completely.
7, data power is not lost.
