Fits intrinsically safe trace oxygen where you need an Analytical Industries GPR-1500 Series. Trace O₂ analyzer/transmitter family with ranges 0–10 / 0–100 / 0–1000 ppm and 0–1% (0–25% class available), LDL 0.05 ppm, T90 under 10 s, and 4–20 mA loop output with optional Modbus on AIS versions.
Key advantages
- Ranges — 0–10/100/1000 ppm and 0–1%
- LDL — 0.05 ppm (50 ppb)
- Response — T90 <10 s (typical)
- Output — 4–20 mA; optional Modbus RTU
- Sensor life — Up to 24 months in <1000 ppm O₂
Typical applications
- Trace O₂ in inert gases.
- IS area oxygen.
- Process ppm O₂ panels.
Selection guide
