NorLab offers custom calibration kits for your portable cylinders. Our two, three, or four-bottle cases provide a safe and convenient method for transporting and storing your NorLab calibration standards. Add a fixed-flow, multiflow or pressure reduction regulator and your calibration kit is complete. We have also introduced a “hands-free” carrying bag to accommodate two cylinders. Carry it over the shoulder or on a belt around your waist. |
