CAUTION

Sensor/Process Application Compatibility

The wetted sensor materials may not be compatible with process composition and operating
conditions. Application compatibility is entirely the responsibility of the user.

CAUTION

The 402 and 402VP sensors are retractable. BEFORE RETRACTING THE SENSOR, be absolutely certain
the process pressure is less than 64 psig (542 kPa abs) and the process temperature is at a safe level!
