industrial conductometer

The instrument is disk-mounted type, dry and wet split structure, which is easy&nbsp to be mounted, operated and maintained.

Backlight dot matrix type, Chinese menu, display of conductivity (uS/cm) of water sample measured (converted into the value at 25°C) and temperature value of the water sample (4~20)mA buffered output signal,upper value and lower value of itscorresponding conductivity can be set freely Upper limit alarm function of conductivity.

Its contact capacity is 2A, 220V AC Power off protection function. Data stored in the instrument can be kept even if off normal power&nbsp cut. It can be in measuring state dispensed with the calibration after starting up the machine again.

Make automatic temperatuer compensation for temperature coefficient of pure water and hyperppure water and conventional electrolytic solution. Its measuring result is accurate. Automatic calibration, automatic switchover function of measuring range.

Protection grade of the casing of electronic unit is IP65, which can prevent water's spraying and dust's invasion RS-232 or RS-485 output interface, which can realize digitized output. Material of measuring cell: stainless steel.
