Quantifit Calibration

OHD, LLC, strongly recommends that your Quantifit be serviced and calibrated on an annual basis. There are many benefits received from the calibration procedure.

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 on an annual basis 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 theQuantifit 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 the unit.


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


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. 

To send in your unit for calibration, please use our RSG Service Form. If you have questions, please call us.
