Pressure Equipment Safety Notes

HOT SURFACE - External Sensor temperature can exceed 93°C (200°F).
Exceeding rated pressure identified as MAOP may cause Sensor failure.
User is responsible for ensuring that all Sensor ports are properly sealed.
It is the responsibility of the user to account for any potential confusion or misuse of gas
equipment with liquid equipment or visa versa.
Materials of construction are chosen based on their chemical compatibility (or inertness) for
general purposes. For exposure to specific environments, check with chemical compatibility
charts before installing.
