The 116L 1000 PSI configuration provides extended calibration cycles with slightly lower fill pressure than 1050 PSI cylinders, offering compatibility flexibility for certain regulator setups.
Applications & Operational Use
-
Confined space entry programs
-
OSHA-required bump testing
-
Industrial plant maintenance
-
Wastewater and utility operations
-
Multi-detector service teams
Methane at 2.5% represents 50% LEL for proper LEL sensor verification.
Oxygen at 17.0% supports oxygen-deficiency alarm testing.
Why Choose 116L 1000 PSI?
-
High total calibration volume
-
Ideal for centralized calibration stations
-
Reduced cylinder replacement frequency
-
Compatible with standard C-10 fixed-flow regulators
