DDS-307A
Characteristics:
1.Double digits LCD display with big screen and blue back light, display conductivity value and temperature value
2.With manual or automatic temperature compensation.
3.There are four types of electrodes for conduction cell constant: 0.01,0.1,1.0 and 10.0cm-1 ,user can select by your need.
4.Automatic switching measuring frequency, measuring ultrapure water with using K=0.01cm-1 titanium alloy electrode and sealing measuring cell
Specifications:
1.Measurement range: 0-1×105 mS/cm
There is the best correspondence point between conductivity measuring range and conduction cell constant
