Limiting Liability

The Quantifit is calibrated to an NIST traceable standard. It is the
only quantitative fit test machine that can be calibrated to an NIST
standard. Calibrating the Quantifit annually will help establish your
good faith concerns for employee health and safety. Whereas the use of
an out of calibration unit may be used against an employer in a
litigation process.

OSHA Compliance

Calibrating the Quantifit annually may exemplify an employer’s desire
to meet all OSHA recommendations concerning respirator fit testing.

Extend Service Life

The heart of the Quantifit is a piston-type pressure engine. In the
calibration procedure the pressure engine is completely disassembled,
cleaned, and lubricated. Much like routinely changing the oil in an
automobile, this can prolong the life of your unit.

Upgrades

During the calibration procedure each unit is upgraded with the latest firmware versions and modifications as needed.

Confidence

Due to our complete system functions tests and quality control
procedures, you can be assured that the unit is functioning properly and
within accepted tolerances.
