Yokogawa pH Sensor DPAS405 for Small Culture Tanks
Yokogawa's pH and ORP analyzers are highly reliable. They feature advanced functions and are useful for a wide variety of applications including water quality management in a broad range of production processes and in medium-sized wastewater treatment plants, or as general pH and ORP control systems.
Based on Yokogawa's track record and years of experience, a comprehensive range of products has been produced to provide solutions best suited to individual applications.
In addition to the PH8EFP, PH8ERP, OR8EFG and OR8ERG standard Ryton pH and ORP sensors, specialty pH and ORP sensors are available for various applications.
Features
Yokogawa pH Sensor DPAS405 for Small Culture Tanks
pH/ORP Sensors for Chemical Processes : DPA405, DPA485
• Extremely long life
span for pH measurement in electrolytic processes
• With the pressurized inner solution there is no
need for a pressure holder.
• The silver barrier
incorporated in the reference electrode inhibits the generation of sulfide
around the liquid junction.

CAUTION ON USE:
This sensor cannot be used outdoors, even when
using with a holder, this sensor cannot be used outdoors due to exposure to
rain or due to condensation at a high humid place. This sensor cannot be used
with a guide- pipe holder. The sensor must be installed in a vertical
position. It can not be installed from below and
in a horizontal position, either.
