Founded in 1991,Shanghai San-Xin Instrumentation Factory is a manufacturer specializing in producing electrochemical analysis instruments and electrodes, located in Cao He Jing High-Tech Park, Shanghai, China.

We are approved by ISO9001:2000 and CE Certification.

Our main products include pH meters, conductivity meters, DO meters, ion meters, water hardness meters, magnetic stirrers and various models of pH electrodes, ORP electrodes, conductivity electrodes, dissolved oxygen electrodes and ion electrodes etc.

We have been designing, manufacturing and selling electrochemical analysis instruments and electrodes for over 17 years. Our company also has technique cooperation relationship with many famous companies which are from the United States, Japan and Korea on developing new products.

We have a team of professors, senior engineers and chemists with wide product experience on designing and developing new electrochemical analysis instruments and electrodes. In 2007, we invented the first YD200 bench top and YD300 portable water hardness meter which measurement by using electrode instead of EDTA titration in the world. In 2008 we promoted MP500 series of electrochemical meters be classified 14 types of electrochemistry meters for covering 12 kinds of electrochemical measuring parameter and the SX600 series of pen type testers. One of the products, MP551 which is a multi-parameter can test pH/mV/ISE/Con/DO just by one meter.

In order to meet demands from various customers, we are continuelly improving our products on designing and creating, meanwhile, we welcome to do OEM business and customize according to customers' special requirements.

If you have any requests regarding our products, please feel free to contact us. We are looking forward to being your reliable and stable supplier for mutual development.
