BW H2S Single Gas Cylinder 25ppm 34 Liter, Cal Gas CG2-H-25-34
Description
BW CG2-H-25-34 is a 25 ppm hydrogen sulfide (H2S) single-gas calibration cylinder in a 34-liter aluminum can. Fully compatible with BW Technologies by Honeywell gas detectors equipped with an H2S sensor, including the GasAlert Clip and GasAlert Clip Real Time series. Use for bump testing and full calibration procedures to verify sensor response and maintain OSHA compliance records.
Gas Specification:
- Gas: Hydrogen Sulfide (H2S)
- Concentration: 25 ppm
- Cylinder size: 34 liters
- Cylinder material: Aluminum
Note: This item ships via UPS Ground due to HazMat restrictions and is not available for expedited shipping. Calibration gas is not returnable. Please check your selection carefully before ordering.
Regulatory Note: Per OSHA 29 CFR 1910.1000 Table Z-2, the H2S ceiling limit is 20 ppm. The 25 ppm challenge concentration in CG2-H-25-34 verifies alarm response above the OSHA ceiling. Employers operating permit-required confined spaces under 29 CFR 1910.146 must maintain calibrated gas detection equipment with current calibration records.

Frequently Asked Questions
What BW monitors is the CG2-H-25-34 compatible with?
The CG2-H-25-34 is compatible with BW Technologies by Honeywell gas detectors equipped with H2S sensors, including the BW Clip 2 Year H2S BWC2-H510, BW Clip Real Time H2S BWC2R-H510, and the GasAlert Max XT II and MicroClip series when configured with an H2S sensor. Call 800.829.9580 to confirm compatibility with your specific monitor model.
Why is 25 ppm used for H2S calibration when the OSHA ceiling is 20 ppm?
Calibration gas concentration is typically set above the target alarm setpoints to ensure the sensor registers a measurable response. For H2S monitors with a low alarm at 10 ppm and high alarm at 15 ppm, a 25 ppm challenge gas generates a clear alarm response that verifies sensor functionality. Per OSHA 29 CFR 1910.1000, the H2S ceiling limit is 20 ppm — confirming the monitor alarms at 25 ppm validates proper sensor response across the working concentration range.
Can I use CG2-H-25-34 for both bump tests and full calibrations?
Yes. The CG2-H-25-34 cylinder is suitable for functional bump tests (to confirm alarm response) and full span calibration procedures (to set sensor output to a known concentration). Pair with a BW Fixed Flow Regulator REG-0.5 LPM for diffusion monitors or the Demand Flow Regulator REG-DF-1 for aspirated instruments and IntelliDoX automated stations.
Why can't this calibration gas ship via expedited or air freight?
Compressed calibration gas cylinders are classified as HazMat under DOT regulations and cannot be shipped by air or via expedited services. The CG2-H-25-34 must ship via UPS Ground only, which typically takes 3–7 business days depending on destination. Calibration gas is also non-returnable — verify your sensor type and alarm setpoints before ordering. Plan ahead to avoid gaps in your gas detection compliance program.
What is the shelf life of BW calibration gas cylinders?
BW calibration gas cylinders have a shelf life of two years from the fill date printed on the cylinder label. Do not use expired gas for bump testing or calibration — degraded gas concentrations produce inaccurate sensor readings and invalidate compliance records. Store cylinders upright in a cool, dry location below 120°F, away from heat sources and direct sunlight. PK Safety recommends tracking cylinder dates and reordering 30 days before expiration.
Can PK Safety help me select the right calibration gas for my H2S detector fleet?
Yes. PK Safety is a BW Technologies by Honeywell authorized reseller and Factory Authorized Service Center. Our gas detection specialists can match the correct calibration gas concentration and cylinder size to your specific BW monitors and usage frequency. We also stock calibration gas for RKI, RAE Systems, MSA Safety, GfG, and Draeger instruments. Call 800.829.9580 or chat with a specialist.
