MIDAS-L-O2S | Honeywell Midas® oxygen (LonWorks cell) 0–25 %vol
MIDAS-L-O2S is a Honeywell Midas® IR cartridge for oxygen (LonWorks cell) (O₂), range 0–25 %vol, electrochemical. It plugs into the MIDAS-T-004 extractive transmitter — not a Sensepoint XCD diffusion head. Sample line up to 30 m FEP at ~500 mL/min.

Transmitter 150×65×153 mm / 0.8 kg; NF₃ pyrolyzer 70×63×85 mm / 0.41 kg; high-temp PFC pyrolyzer 100×101×140 mm / 1.36 kg.
Why this SKU
Midas is extractive: the cell sits in the tool cabinet while FEP pulls sample from the valve box. oxygen (LonWorks cell) uses electrochemical. Pyrolyzed species need MIDAS-T-00P / T-HTP / T-NP1 or the cartridge will not read.
Mates and spares
MIDAS-L-O2S mates to MIDAS-T-004. Pump MIDAS-A-007, internal filter MIDAS-A-009. Do not substitute an electrochemical cartridge for this IR cell. Calibration notes live on product-2679.
Typical applications
Gas cabinets, VMBs, wet benches and CVD/etch exhaust. MIDAS-L-O2S locks gas and cartridge life; budget transmitter, pump A-007 and internal filter A-009 on the PM cycle.

Install and sample line
Wall-mount MIDAS-T-004 on the pre-drilled chassis or DIN kit A-036, then insert MIDAS-L-O2S. Sample 1/8″ID×1/4″OD FEP to 30 m; exhaust 1/4″ID×3/8″OD to 30 m. End-of-line filter 0780248 or 1830-0055/0027 by gas. 24 VDC (−15%/+10%) or PoE 48 V; pyrolyzer load up to 12.95 W. 0–40 °C, 0–30 °C with pyrolyzer.
FAQ
- How to pick spares?
- Match gas code and S/E/IR prefix in the family matrix; no look-alike substitutes.
- Which product line is MIDAS-L-O2S?
- Honeywell Analytics Midas / Midas-M extractive cartridge & transmitter family.
- Install notes?
- Mind sample tubing, flow and leaks; ventilate/exhaust per the manual.
- Cartridge warranty?
- S ≈ 1 year; E extended ≈ 2 years; LEL has separate cal-life notes.
- Interchangeable with Sensepoint XCD?
- No. Pneumatics, mechanics and P/N systems differ.

Quote and lead time
Stock and lead time are batch-based. If an E cartridge is short, look at the same-gas S cartridge. Pyrolyzed gases need the pyrolyzer ordered with the transmitter.
