Use ACCURRA-Hz, Infinity-Tx. Solvent vapour needs an oxygen reading in vent and blanket lines. Hazardous area; confirm certificate.
The measurement and why it matters
Solvent vapour needs an oxygen reading in vent and blanket lines. This is a good fit, with one configuration or sample-handling point to confirm before we quote.
Solvent vapour, fine powders and reactive intermediates are handled under inert gas, and the oxygen limit in vent and blanket lines is a safety figure. Hazardous-area units and a loop-powered transmitter cover the classified locations.
ACCURRA-Hz uses an enclosure certified for Gas Group IIC, Zone 1 and 2, T6, and INFINITY-Tx is a loop-powered two-wire transmitter. Confirm the certificate against your zone before ordering; we make no SIL claim.
Typical buyers in India: pharma and fine-chemical plants (several are customers). Where this matches your plant, send us the gas, range, pressure and temperature at the tapping point and we will confirm the analyser and sample path.
Models and ranges
| Model | Measures | Range | Sensor and notes |
|---|---|---|---|
| ACCURRA-Hz | Oxygen, hazardous area | Percent and trace | Gas Group IIC, Zone 1 and 2, T6 |
| INFINITY-Tx | Oxygen transmitter | Percent O2 | Loop powered two-wire, hazardous areas |
Process notes
What the analyser reads here
Gases of interest: O2. Analyser fit: ACCURRA-Hz, Infinity-Tx.
The table above lists each model with its range; where a row says to confirm the range, we check it against the datasheet for your application before quoting.
What to settle before ordering
Hazardous area; confirm certificate.
We would rather confirm these points at the start than discover them at commissioning, so please include them with your process details.

Sampling and installation
- Every ACCURRA-S has an internal fine filter and rotameter. Regulate sample pressure and flow externally; the catalogue recommends about 1 LPM and a sample pressure of 2 to 10 psig.
- Keep sample lines short, clean and dry, and vent the sample somewhere safe.
Send us your process data
The same pre-order design inputs our engineers design from, online. Fill in what you know, leave the rest. Your draft saves as you go, and you can print or send it when ready.
What the data sheet asks for
Send what you have and we will ask for the rest.
- The gases to measure, the range, and the accuracy you need
- Background gases and their typical composition
- Sample temperature, pressure and dew point at the tapping point
- Dust level, and whether the gas carries tar, oil or condensable vapour
- Process connection and, for ducts, the duct diameter
- Where the sample vents to, and at what pressure
- Area classification of the tapping point and of the analyser location, and the IP protection needed
- Distance between the tapping point and the analyser
- Outputs you need: 4-20 mA, dual range, relays, Modbus RTU
- Calibration approach, calibration gas available, and whether blowback is required
- Utilities at site: power supply, instrument air, nitrogen, steam and cooling water, and the ambient temperature range
- Gases and ranges: O2
- The point to confirm: Hazardous area; confirm certificate.
