SJG-2084 Industrial Acid Concentration Meter

SJG-2084 is the new generation English microcomputer type top grade instrument produced in our company which is characterized byEnglish show,English menu operation, intelligence, multi-function, high measure property, strong environmental suitability, etc.. It can universally apply to fire power, chemical industry and so on for inspecting the regeneration concentration in the process of extracting the ultra- pure water with the ion-exchange method and preparing the pickle alkali of boiler and pipe for monitoring the hydrochloric alkali concentration continuously.

 Features :

Intelligence: SJG-2084 English on line alkali densimeter adopts the high precision AD convert and single chip micro-processing technology which can fulfill the HCL concentration measurement, temperature measurement, temperature automatic compensation, range automatic change, instrument self inspection, etc..

High reliability: 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 dustproof: The degree of protection is IP65 which is suitable for outdoor operation.

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.

Phrase-sensitive detection: remove the affect on the hydrochloric alkali concentration measurement by the wire.

Automatic change the measurement frequency: avoid the polarization of electrode and improve the measure precision.
