| The conductivity Standard Solutions and pH Buffers are used for factory calibration. Regular use of these solutions is recommended to ensure specified instrument accuracy. Frequency of conductivity recalibration depends upon use, but once every month should be sufficient for an instrument used daily. pH models, depending upon use, should be recalibrated with pH 7 Buffer every 1-2 weeks, and checked with pH 4 and/or 10 Buffers at similar intervals. pH Sensor Storage Solution is recommended for keeping the pH sensor wet. Myron L solutions are available in quart / 1 ltr., gallon / 3.8 ltr. and 2 oz. / 59 ml plastic bottles, ready to use. (Custom value standards only offered in gallon / 3.8 ltr. size bottles.) |

| The Seraphin® waterdraw system is comprised of bottom drain stainless steel provers and at least one top drain measure mounted on top of a stainless steel water reservoir. The provers drain via gravity into the reservoir. A 5 HP pump takes suction from the bottom of the reservoir tank and discharges to an inlet professional fitting of the customer's dynamic pipe prover, via a portable quick-connect professional hose. The discharge side of the customer's pipe prover connects to a stainless steel manifold which is plumbed to the top neck of each individual prover. Various combinations of Seraphin® provers can be used to calibrate different size pipe provers. A supplier of solenoid operated cock at the inlet of the waterdraw manifold is connected, through relays in the control panel, to the detector switches of the pipe prover. The system will shut down when the sphere reaches the second detector switch. The volume between detector switches will be captured in the Seraphin® measures. |
