About the 3100
Hach's Orbisphere 3100 is the most rugged, reliable and long-lasting portable optical oxygen analyzer in the industry designed to withstand the harshest environments with a stainless steel enclosure. Fast results, longer calibration intervals and easy on-site maintenance make it the most stable sensor with the longest calibration interval in the beverage and power industries.

How the 3100 LDO works
The 3100 dissolved oxygen analyzer is equipped with a measuring LED that emits a pulse of blue light and a photo diode as a light detector. The instrument is also equipped with a sensitive luminescent coated spot that is exposed to the sample.

  • The measuring LED emits a pulse of blue light which irradiates the back of the oxygen sensitive spot. The coating material reacts with luminescence and emits a pulse of red light where the intensity and time delay are measured.
  • When oxygen is present in the sample stream and contacts the coating, the intensity and time delay of the luminescent light emission are changed.
  • The more oxygen molecules come into contact with the coating, the lower the intensity and the shorter the duration of the red radiation. These changes in the profile curve are used to determine the measurement.
