## The measurement and why it matters

Argon cover gas and nuclear glove boxes track oxygen and moisture. This is a good fit, with one configuration or sample-handling point to confirm before we quote.

Research and nuclear users need low oxygen and moisture in argon or nitrogen atmospheres and a clear record of instrument health. ACCURRA-S stores calibration, alarm and fault records and password-protects calibration and set-up.

Volumes are often small and closed, so the sample drawn by the analyser has to be returned or limited. Orders are small and technical, and we treat each set-up as an application engineering job.

Typical buyers in India: DAE and its labs (an existing customer). 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 |
|---|---|---|---|
| 3015 | Trace oxygen | 0 to 1000 ppm (min range 0 to 100 ppm) | Electrochemical; no internal pump, no auto-calibration |
| M015 | Dew point | -80 to +20 C | Ceramic sensor; no internal pump, no auto-calibration |

## Process notes

### What the analyser reads here

Gases of interest: O2 ppm, moisture. Analyser fit: ACCURRA-S 3015 + M015.

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

Procurement through DAE; validate each use.

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.
- Models 3015, M015, 3130 and 3190 are supplied without an internal sample pump. Tell us the sample pressure and we will confirm the sample path or add a pump.
- Models 3015 and M015 have no auto-calibration, so plan a calibration routine with the right reference gas.
- Keep sample lines short, clean and dry, and vent the sample somewhere safe.

ACCURRA-S sample specification: non-corrosive, non-toxic, non-flammable, non-condensing and dry, free from entrained oil; sample pressure 2 to 10 psig, regulated externally; flow about 1 LPM; dust below 3 micron. Where your sample differs, we design conditioning around it.

- 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 ppm, moisture
- The point to confirm: Procurement through DAE; validate each use.
