Waltron 9165 LDO Dissolved Oxygen Analyzer

Fits low-level dissolved oxygen monitoring where you need a Waltron 9165 optical LDO analyzer with ppb/ppm ranges and multi-stream electronics options.

Key advantages

• Technology — Optical luminescent DO sensing (9165 LDO)
• Ranges — 0–200 / 2000 ppb; 0–20 / 45 ppm (sensor dependent)
• Accuracy — ±0.5 ppb at 1 ppb or ±2% of displayed value
• Streams — Up to four sample streams on one electronics platform
• I/O / power — 4–20 mA options; 100–250 VAC or 24 VDC

Typical applications

• Boiler feedwater and condensate DO at ppb levels.
• Process water DO with optical sensor maintenance profile.
• Multi-stream analyzer panels sharing one transmitter.

Selection guide

• Range / sensor — ppb vs ppm sensor head
• Streams — 1 to 4 sample streams
• Power — AC vs 24 VDC
• Outputs — 4–20 mA channel count

Common mistakes

• Ordering ppm sensor for sub-ppb boiler chemistry — lock the ppb range.
• Assuming four streams are populated without ordering the multi-stream option.
• Ignoring sample conditioning (flow/temp) for optical DO.

When to RFQ / what to tell us

1. ppb vs ppm range; number of streams.
2. Power and 4–20 mA needs.
3. Quantity and ship-to.
