PSR‑11‑39‑MHD Oxygen Sensor
|Megalodon, Juergensen Marine Hammerhead (tighter mV)
The Analytical Industries (AI) PSR-11-39-MHD is a special version of the PSR-11-39-MD which provides a slightly higher mV range. Do not use the MHD version unless recommended by the rebreather OEM for your specific unit because otherwise some sensor validation checks may produce misleading results.
- Accuracy within +/- 2% of full scale
- Response time is 6 seconds
- Conformal coating
- Temperature compensated
- Hydrophobic membrane
AI brand diving sensors ship with the documentation of a final pressure test for each sensor. The sensor is tested at approximately one ATA in air and 100% oxygen, then tested again at 1.8 ATA in oxygen, and the millivolt readings are recorded for all measurements. The results document that the cell is within specifications for current and linearity up to a PO2 exceeding 1.6 ATA. The dated test results are included in the package with each individual sensor.
