Dissolved oxygen analyzer 7118 model

The dissolved oxygen analyzer 7118 model is a measuring instrument designed to continuously measure the dissolved oxygen concentration of condensate and feed-water used in boiler plants. Since dissolved oxygen is a major factor in corrosion or scale, it must be monitored continuously.
天天斗牛 The 7118 model is capable of performing measurement stably by the diaphragm polarography process without contaminating samples. Optional "one-touch calibration" allows the operator to perform calibration easily.

Features

  • Diaphragm polarography process
  • Excellent maintainability
    • Optional "automatic calibration cell unit" allows the operator to perform one-touch calibration.
    • Only calibration and sensor wiping are performed as daily maintenance. (one standard maintenance/two months as standard)
  • Wide measurement range
  • Free power source
  • Capable of connecting conventional 7115 cell
Measurement principle Diaphragm polarography process
Measurement range (1) LOW range
(2) HIGH range
* During calibration
The setting range shall be either (A) or (B) as shown below.
The setting range shall be either (A) or (B) as shown below.
Fixed to mg/L. Range is switched automatically during calibration.
