DDG-760A electromagnetic acid-base concentration meter/conductivity meterDetailed product description：

DDG-760A electromagnetic acid-base concentration meter/conductivity meter

Application:
Mainly used for continuous monitoring of conductivity or acid/alkali concentration in power plants and departments such as petroleum, chemical, pharmaceutical, and environmental protection

Key Features:
The instrument is an online monitoring device with a single-chip microcomputer that can accurately compensate for the temperature of the solution
Using electromagnetic induction method to measure the conductivity of solution, without polarization phenomenon, accurate measurement, and easy maintenance
It can measure the concentration of HCl solution or NaOH solution, as well as the conductivity of general solutions
Large screen dot matrix LCD display, which simultaneously displays the temperature and concentration (or conductivity) of the measured solution. The concentration (or conductivity) value has been automatically converted to the value at 25 ℃
Can output (4-20) mA isolated current signal, and the measurement range corresponding to the output signal can be adjusted arbitrarily
Digital communication function with RS-232 or RS-485 (optional)
Equipped with upper and lower limit alarm functions and power-off protection function
Adopting a metal chassis with IP65 protection level
