Mesa’s primary flow standards are a critical link in the chain to protect workers, monitor an ever-changing environment, or authenticate process control. To verify that your primary standard has not been compromised by inadvertent damage, environmental factors, or time and use, Mesa recommends annual service and calibration of your DryCal primary gas flow standard.
Our ISO accredited facility provides an annual NIST-traceable calibration with a secure audit trail that backs and supports your hard work. Additionally, our periodic factory care and maintenance protects your instrument from:
- Time – Your instrument is made to last a lifetime with proper care and maintenance. However, extensive use without factory service can wear down components over time and affect performance.
- Contamination – Dust, dirt, particulate, chemicals and other items may affect performance over time. Some contamination may not be visible and your unit could appear normal, but performance could be affected.
- Abuse – Your instrument has a durable protective care with non-slip grips as well as internal shock absorbers for field use. However, performance could still be affected by accidental mishandling that could damage connections and loosen timers, even if the unit appears undamaged.
- External Influences – Environmental factors such as unit storage and operating conditions could cause changes in performance over time.
To protect your workers and hard work, your DryCal instrument should receive the expert service and quality calibration that befits a precision measuring tool. Annual service and calibration at our ISO accredited facility will be performed by Mesa’s trained Validation Experts, without the need for a third party.
What is included in Mesa’s factory calibration?
Mesa performs the following factory maintenance and repair on instruments during calibration:
- Disassembly and inspection of the instrument for wear, defect, contaminants and damage
- Full cleaning, repair and/or replacement of parts as needed
- Battery test/replacement
- Upgraded firmware and hardware
- Temperature and pressure sensor calibration if required
- Multi-point flow calibration with adjustment
- NIST traceable calibration certificate with As-Found (pre) and As-Left (post ) data
- 90 day service warranty
OSHA provides the following recommendation in their technical manual* in regards to calibration equipment recertification:
- “This chapter provides basic information related to sampling air contaminants. These instructions are essential for acquiring documented and valid exposure data that will be defensible in the event of contested citations.”
- “Assure that the calibration equipment is within its prescribed calibration interval”.
