Yokogawa is working with HAMILTON to provide best-in-class dissolved oxygen sensors. Dissolved oxygen measurements in the parts per billion range are critical in, but not limited to power generating plants. Maintaining a low level of dissolved oxygen in boiler feedwater assures that corrosion of certain components is minimized. A reliable measurement of ppb dissolved oxygen helps to reduce downtime and improve efficiency. The OXYGOLD G sensor accurately measures trace levels of dissolved oxygen down to 1 ppb. The modular design of the membrane cartridge allows simple recharging of the electrolyte or membrane replacement. It is not uncommon for the OXYGOLD G sensor to not require maintenance for over 8 months after installation.
