ACCURRA-S 3015 plus M015 measures trace oxygen (0 to 1000 ppm) and dew point (minus 80 to plus 20 C) from one sample, in one enclosure. Oxygen and moisture are the two signs of air ingress, so reading both speeds up leak diagnosis.
Specifications
| Item | Specification | Notes |
|---|---|---|
| 3015 | Oxygen 0 to 1000 ppm (min 0 to 100 ppm) | Electrochemical |
| M015 | Dew point -80 to +20 C | Ceramic sensor |
| Notes | Sensor bypass valve supplied; no auto-calibration; no internal sample pump | |
| Independence | Own electronics, outputs, relays and Modbus ID per channel |
From the current Sarvesh product datasheets and company profile. Specifications may change without notice as products improve. The final responsibility to check that a product meets the process and analyser requirement remains with the customer.
Key features
- Independent electronics, microcontroller, 4-20 mA, relays and Modbus ID per sensor
- Common pneumatics and one fine filter
- Calibration history and password protection
How it works
Oxygen and moisture are the two signs of air getting into a dry inert gas, and they usually rise together. Reading both gives a faster diagnosis of a leak than either alone.
The pharma note recommends this pairing for lyophiliser back-fill gas and the catalogue lists O2 ppm with dew point in N2, H2, Ar and He. The sensor bypass valve isolates both sensors during start-up and purging.
Requirements and limits
- Safe-area analyser; the standard sample specification applies.
Selection guidance
See the dual-gas analyser page for the full list of combinations.

What backgrounds?
Nitrogen, hydrogen, argon and helium.
Is auto-calibration available?
No, not on 3015 or M015.
Do I need a sample pump?
An internal pump is not available; use a regulated sample pressure or external pump.
Can I add hydrogen?
The catalogue lists O2 ppm with H2 percent in nitrogen as a separate pairing.
