DDG-2080C INDUCTIVE ONLINE TDS METER
Industrial inductive conductivity TDS meter is the new generation English microcomputer type top grade instrument produced in our company which is characterized y English show, English menu operation, intelligence, multi-functional, high measure property, strong environmental suitability, etc.. It can be widely used in continuous monitoring of electrical conductivity in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water.The secondary meter with constant conductivity electrode 1.0 or 10 measuring common liquid; with 0.1 or 0.01 electrodes, can accurately measure the conductivity of pure water or ultra pure water, especially suitable for the on-line monitoring of power plant boiler feed water and steam condensate water and high water conductivity.
Industrial inductive conductivity meter? adopts the high precision AD convert and single chip micro-processing technology which can fulfill the conductivity?measurement, temperature measurement,?temperature automatic compensation, range automatic change, instrument self inspection, etc..
Parts integrate in a circuit board without any complex function switch, regulation knot or potentiometer.
Strong resistance to interference
Current output adopts photoelectricity coupling and isolation technology which holds strong resistance to interference and realizes long distance transmission as well as good electromagnetic compatibility.
Design with waterproof and dust-proof
The degree of protection is IP65 which is suitable for outdoor operation.
It provide 25℃ base temperature translation of the measured conductivity, so the conductivity value at 25℃ can be directly displayed. This is particularly suitable for measurement of water quality in power plants.
Range automatic change
Realization of range automatic change within the range of the electrode covered.
RS485 communication interface
Easily connects to the computer for monitor and communication.
Remove the affect on the hydrochloric acid concentration measurement by the wire.
Automatic change the measurement frequency
avoid the polarization of electrode and improve the measure precision.
Display fully in English and user-friendly interface
It uses high-resolution lattice graph-type LCD display module, and all data, status and operation prompts are displayed in English, without any symbols or codes defined by the manufacturer.
Simple menu structure and text-type man-machine interaction
Compared with traditional instruments, is provided with many new functions. However, with sorted menu structure and the operation manner similar to PC, it can be conveniently and simply operated. Users need not remember the operation steps and sequences, and can operate it even without a user manual, just following the prompts on the screen.
Multi-parameter display in the same screen
It displays several parameters in the same screen, including conductivity, output current, temperature, time and status. The main display area displays conductivity in 10×10mm, very striking and readable even far away; The 6 auxiliary display areas display in 5×5mm the output current, temperature, status, week, date and time, designed to meet different habits of users and provide time base for the instrument.
