Features and Benefits:

  • Full gas portfolio and blends for nearly all industrial, marine, and laboratory applications, including multi-gas packs for four-gas detectors.
  • Many cylinder sizes on request — 1AL, 2AL, 8AL, 10AL, 5ELR, 6D & 6DM, 7HP and 7EOC, as well as 65ALR and 65DA — so you can choose exactly the gas volume that matches your usage pattern.
  • Reactive and non-reactive mixtures — cylinder and valve materials are matched to the gas type, ensuring stability for both CO₂ in air and chlorine in nitrogen.
  • Long shelf life up to 60 months for most non-reactive gases; typically 24 months for H₂S blends and other reactive compounds.
  • NIST-traceable certificate supplied with each cylinder for documented accuracy and traceability.

Specifications:

  • Typical gases: O₂, CH₄, CO, H₂S, SO₂, NH₃, Cl₂, NO/NO₂, etc.
  • Valve / connection: 5/8"-18 UNF C-10 (standard) · CGA 600 · 1/4" NPT
  • Fill pressure: Up to 500 psig / 35 bar for 34 L cylinder
  • Tolerance & certificate: ±2% (≥ 51 ppm) / NIST-traceable certificate
  • Shelf life: 6–60 months depending on gas mixture
Calgaz covers all calibration needs, from simple bump tests of portable detectors to precise calibration of fixed systems. The wide range means you rarely need special blends with long lead times. Cylinders are lightweight aluminium or steel models with a universal C-10 valve, so they fit Geopal’s regulator types (700- and 800-series) without adapters. The result is more uptime, fewer error sources, and full compliance with both internal procedures and regulatory requirements.
A correctly calibrated gas detector is critical to safety — and accuracy starts with the calibration gas. Calgaz’s stable blends and long shelf life reduce test intervals, minimize gas waste, and ensure your detectors deliver reliable measurements day after day. At the same time, the broad assortment and universal valve standard make it easy to streamline procurement and logistics across the entire organization.

A reliable gas detection system starts with a thorough assessment of your workplace environment. With years of experience identifying risk areas and designing tailored solutions, we can help determine whether this product is the right fit for your needs.

Whether you need this product as a standalone solution or as part of a larger system, we’ll make sure it’s aligned with your workplace’s specific requirements. We work closely with you to ensure the solution meets both safety standards and the unique challenges of your operations.
