Who should choose it and who should not

What to verify before ordering

Confirm that the 1/4 inch male NPT thread matches the port on your equipment and that the centre-back orientation fits the available clearance. Check that the +/-3-2-3 percent accuracy class meets your calibration requirements and that the Proposition 65 notice is acceptable for your facility.
