CST900A constant Coulomb corrosion Tester

Introduction

This instrument applies to the ocean pier , bridge construction and other concrete works on-line corrosion monitoring , also applies to plant high water and cooling water circuit corrosion monitoring , underground pipelines and other on-site inspection and monitoring of corrosion rate ; compared with available experimental scene coupon more comprehensive and rapid corrosion and corrosion control information.

Features

CS900 has an easy to carry, easy to operate, rapid measurement , display the results visually , etc., can make manual measurements , the instrument can be installed in the field timed automatic measurements ; This instrument also has a calendar clock and large flash memory can store up to 4000 group . Communication part adopts RS232 interface , the measurement data can be uploaded to a PC dedicated software for data processing and graphically displayed on a PC media resistance , polarization resistance , corrosion rate and so on.
