Start-up Guide
Intended Use
The phx42 analyzer can be used to safely collect data in Class 1, Division 1
hazardous locations. This includes:
• Refineries & Chemical plants
• Gas or oil pipelines
• Compressor and pump stations
• Oil field production facilities
• Anywhere VOCs are present
• Indoor and outdoor environments
The phx42 must be installed in a backpack while in hazardous locations.
• The phx42 should be upright in the pack with the north end (with probe port)
facing up.
• The phx42 must not share a pocket with any other items or tools.
• Backpack should fit snugly so the phx42 does not tilt away from the tech or tip
over. This can cause probe kinks.
Overnight equipment storage and calibration should be done indoors at or near room
ambient conditions (15-25 °C or 59-77 °F) with a maximum humidity of 85%.
