Why do I need to recalibrate?
Generally, gas detectors are placed in a potentially hazardous area that may be hard on sensor systems. Sensor systems degrade over time and the zero and span levels will vary as the sensors age and are exposed to harsh environments. All sensors have finite lifespans and will have to be replaced periodically. To ensure that the sensors are responding correctly, each sensor needs to be exposed to the gas that it is detecting to insure it is working and is reading accurately. This ensures the safety in the workplace as well as preventing the frustration of false alarm conditions. Many sensors will read zero concentration and appear to be working and then also read zero when exposed to gas if they are no longer working. Therefore, bump testing and calibration are the way to know if the sensor in question is indeed working correctly.
How often do I need to recalibrate?
ACD gas generators must be recalibrated every 12 months to maintain NIST certification. If NIST traceability is not required, the unit can be used for longer between recalibrations.
GazCal is not NIST traceable, so the 12-month rule applies to ACD only.
ACD calibration gas instruments
To maintain NIST certification, ACD instruments must be recalibrated every 12 months. ACD and Spantech offer a back-up service which enables the CAL2000 to be re-certified every year to USA NIST standard +/-10% or +/-5% accuracy on some cases on request.
My instrument is due for calibration, what do I need to do? Contact Customer Service to obtain an RMA #.
ACDGazCal servicing and recalibration
If your GazCal requires servicing or recalibration, please contact Spantech before sending your unit to us.
Once your unit arrives, we will inspect it and provide a quotation for recalibration and any corrective work required. After the quotation has been approved, our engineers will carry out the work and aim to dispatch the unit within 48 hours of approval, helping to keep downtime to a minimum.
