GX-2012 Gas Detector Calibration Kits

Gas detector calibration involves two main steps: a zero calibration using clean air or inert gas, and a span calibration using a certified calibration gas at a known concentration. Connect the calibration gas to the detector inlet, allow the reading to stabilize, and adjust the instrument's span accordingly. Always use NIST traceable calibration gases that match the target gas type and concentration range specified by the detector manufacturer.

Yes. Gas detectors require regular calibration to maintain measurement accuracy and reliability. Sensor sensitivity can drift over time due to age, chemical exposure, and environmental conditions. OSHA guidelines recommend bump testing before each use and full calibration whenever a bump test fails or per manufacturer-specified intervals. Using certified, NIST traceable calibration gases ensures your detector responds accurately to real hazardous gas concentrations.

The RKI GX-2012 typically monitors combustible gases (LEL), oxygen (O₂), carbon monoxide (CO), and hydrogen sulfide (H₂S). Calibration requires a four-gas mixture or individual certified calibration gases for each target component. SpecGas supplies NIST traceable CH₄, H₂S, CO, and O₂ calibration gases in concentrations appropriate for GX-2012 span calibration, available in both disposable and refillable cylinders.

Calibration gas cylinders have a defined shelf life that varies by gas type and concentration. Reactive and toxic gases such as H₂S and CO may have shorter stability windows. SpecGas's proprietary cylinder treatment process and Stability Guarantee extend shelf life significantly. Always check the cylinder's expiration date before use, and replace cylinders that are expired or show signs of concentration drift to maintain accurate calibration.

Yes. SpecGas specializes in custom calibration gas blends tailored to exact customer specifications. Whether you require specific PPM or PPB concentration levels, unique gas combinations, or tolerances adapted to your detector's calibration range, SpecGas blends all mixtures in-house using gravimetric techniques. Custom blends are available in disposable and refillable cylinders and are fully NIST traceable.

Yes. SpecGas offers calibration gases in disposable aluminum and steel cylinders specifically designed for field applications and remote operations. These compact, portable cylinders are ideal for on-site bump testing and calibration of the GX-2012 where refillable high-pressure cylinders are impractical. Disposable cylinders are also approved for overseas shipping, making them suitable for global field operations and confined-space monitoring programs.
