Product Description
GASCO | 58L-252-2 | X02NI99CP586155 | Chlorine 2 PPM | Balance Nitrogen | 58 Liter | connection | Certificate NIST | Made in the USA
The Calgaz 58L-252-2 is a certified single-component reactive calibration gas standard containing 2 PPM Chlorine (Cl2) balanced in high-purity Nitrogen. Packaged in a lightweight, high-integrity 58-liter aluminum cylinder (Calgaz 2AL / 8AL equivalent) with an industry-standard C-10 valve connection (5/8"-18 UNF), this standard provides accurate span calibration, bump testing, and routine maintenance for electrochemical chlorine sensors in water treatment plants, chemical manufacturing, pulp/paper facilities, and municipal disinfection stations.

Key Applications & Instrument Compatibility
- Target Applications: Engineered specifically for chlorine leak monitoring, water treatment dosing controls, scrubber monitoring, and occupational exposure limit (OEL) sensor calibration.
- Detector Brand Compatibility: Direct drop-in span gas for portable and fixed electrochemical chlorine detectors from leading manufacturers, including Honeywell / BW Technologies (GasAlert Extreme, MicroClip with Cl2 sensor, ToxiPro), Industrial Scientific (GasBadge Pro, Radius BZ1), MSA Safety (ALTAIR 4XR / 5X with XCell Cl2 sensor), RKI Instruments, and Dräger (Pac 6500 / 8500, Polytron series).
- Regulator Requirements: Important: Due to the corrosive and reactive properties of Chlorine, this cylinder requires a dedicated Stainless Steel C-10 fixed-flow regulator (such as 0.5 LPM or 1.0 LPM Calgaz Model 715 SS / GASCO 70-SS) or a PTFE-lined reactive gas regulator. Do not use standard brass regulators.
- Traceable Quality: Each cylinder is individually lot-serialized and accompanied by an NIST-traceable Certificate of Analysis (COA) available via QR code on Cylinder Label.
Hazmat Transport Notice: Compressed reactive gas cylinders are regulated hazardous materials.
