Apex Instruments is now offering nozzle calibrations and serial number engraving.
Nozzle diameters will be calibrated to meet US EPA Method 5 requirements. Stainless steel and alloy 600 nozzles will be physically engraved to display the nozzle diameter, part number, and unique ID. All other nozzles will be identified by certificate only. This service can be requested when purchasing new nozzles. Previously purchased nozzles can be sent to the Technical Services Group to be calibrated.
