Page 7: Introduction
1.2 Probe Description The Honeywell probe is housed in either PVC or Stainless steel casing. One end has a 1” NPT male thread for mounting. The sensor extends from the housing and is covered by a protective guard (of the same material as the casing) which allows sample entry while preventing physical damage. -
Page 8: Operating Principal
1.3 Operating Principal When the probe is placed into the sample stream, oxygen diffuses through the membrane and is reduced at the cathode, and an equal amount of oxygen is generated at the anode. The diffusion continues until the oxygen partial pressure on both sides of the membrane is equal and a balance exists. The electrical circuit is designed such that the current necessary to maintain this equilibrium is converted to read out the dissolved oxygen concentration in the solution. -

Probe membrane must be kept wetted both in the process and during storage. See Storage under Maintenance section. The silicone membrane surrounding the D.O. probe is permanent. If this membrane is removed by user for any reason, the warranty on the D.O. probe is voided 11/07 DL5000 Dissolved Oxygen (D.O.) Probe – User’s Manual... -

After these actions are taken, a cleaning schedule should be established. ATTENTION Never use a brush to clean a Honeywell D.O. probe as it can cause a tear in the probe membrane rendering it inoperable. This type of abuse is not covered under probe warranty. -
Page 22: Probe Storage
Short term The Honeywell probe arrives from the factory with a red cap on the end of the probe. This cap contains a 3% solution of Isopropyl alcohol and water. The water keeps the probe wetted until it is put into the process. -
