Description
The Orbisphere M1100 Luminescent Dissolved Oxygen Sensor (Part Number M1100‑S00) is an optical sensor designed for continuous inline measurement of dissolved oxygen at low concentrations up to 2 ppm. It employs advanced luminescent technology, eliminating the need for membranes and electrolytes to reduce maintenance and ensure long‑term stability. Mechanical robustness and resistance to Clean‑In‑Place (CIP) processes offer extended operational life and reliable performance in beverage production and process water monitoring.
Advantages M1100‑S00
- Minimal drift with long calibration interval — M1100‑S00
- Luminescent optical technology with no membrane or electrolyte degradation — M1100‑S00
- High precision measurement down to ppb levels — M1100‑S00
- Fast measurement frequency for responsive process control — M1100‑S00
- Robust construction designed for CIP resistance — M1100‑S00
- Suitable for inline beverage and process applications — M1100‑S00
Usage Instructions
Install the M1100‑S00 sensor into the corresponding Orbisphere analyzer or controller according to the manufacturer’s mounting instructions. Perform a single‑point zero calibration using high‑purity oxygen‑free gas (e.g., 99.999 % nitrogen). Regular weekly CIP procedures help maintain accuracy without frequent recalibration. Follow specific cleaning, calibration, and storage guidelines in the official Hach documentation.
