Product Description
Calgaz 103L-1 | AIZP10 | Zero Air (20.9 % Oxygen balance Nitrogen) Cylinder Type: Steel, Connection: C-10, Certification NIST, Made in USA
Calgaz 103L-1 Zero Air Calibration Gas Cylinder | AIZP10
Gas Blend: Zero Air (20.9% Oxygen, Balance Nitrogen) | High-Purity Hydrocarbon-Free Baseline Standard | 103 Liter Disposable Steel Cylinder | C-10 Valve
The Calgaz 103L-1 is a high-purity synthetic Zero Air calibration standard packaged in a portable 103-liter disposable steel cylinder. Containing an exact atmospheric concentration of 20.9% Oxygen balanced in Nitrogen with certified ultra-low background impurities (< 0.1 PPM Total Hydrocarbons), it serves as the essential baseline zero reference for portable gas detectors, Photoionization Detectors (PID), Flame Ionization Detectors (FID), and continuous emission monitoring systems (CEMS).
Instant Digital Verification: Every cylinder includes an integrated QR code on the cylinder shoulder label, allowing safety technicians immediate mobile access to view and download the lot-specific NIST-traceable Certificate of Analysis (COA) and Safety Data Sheet (SDS) directly in the field.

Applications & Regulator Compatibility
- Standard C-10 Hardware: Connects to all standard C-10 connection regulators (5/8"-18 UNF), including 0.5 LPM or 1.0 LPM fixed-flow regulators and Demand Flow Regulators (DFR) for automated docking stations and pumped instruments.
- Baseline Instrument Zeroing: Provides a true hydrocarbon-free zero point in environments where ambient background air may contain traces of vehicle exhaust, VOC vapors, or moisture that skew sensor baselines.
- PID & FID Zero Standard: Critical for zeroing Photoionization Detectors (MiniRAE 3000+, MultiRAE, Ion Science Tiger) and Flame Ionization Detectors prior to applying 100 PPM isobutylene or span gases.
- Oxygen Sensor Span Standard: Serves as an exact 20.9% O₂ span reference gas to calibrate electrochemical oxygen deficiency sensors on all multi-gas monitors (MSA Altair, Industrial Scientific Ventis, Honeywell BW, RKI).
- Extended 48-Month Shelf Life: Stable non-reactive air chemistry delivers 4 full years of shelf stability, minimizing inventory waste for emergency response caches.
Fulfillment & Traceability Notice: Sourced and certified directly via Cal Gas Direct. Orders include direct NIST manufacturer certificates available via QR code on Cylinder Label
Calgaz 103L-1 (Airgas CRM Part Number AIZP10), distributed by Cal Gas Direct, is a certified Zero Air calibration standard packaged in a portable 103-liter disposable steel cylinder (DOT-39) with a standard C-10 (5/8"-18 UNF) outlet valve. The blend consists of 20.9% Oxygen (O₂) balanced in ultra-high purity Nitrogen (N₂) with certified trace background limits of less than 0.1 PPM Total Hydrocarbons (THC), 1 PPM CO, 1 PPM CO₂, and 2 PPM moisture. Rated to a working pressure of 1,000 psig with an extended 48-month shelf life, every cylinder features a scannable QR code on the cylinder label for instant digital retrieval of its serialized NIST-traceable Certificate of Analysis (COA). It is the recognized zero reference gas for photoionization detectors (PIDs), flame ionization detectors (FIDs), and the 20.9% span reference for electrochemical oxygen sensors on multi-gas monitors from MSA, Honeywell / BW Technologies, and Industrial Scientific.
