TRG Technologies Measurement Solutions, Inc. Sphere Inflation Pump (Model T-IP-1-4) is used to manually inflate spheroids to a desired diameter using a liquid solu- tion such as an ethylene glycol water mix. The inflation pump can be used to inflate spheroids from most manu- facturers. The sphere inflation pump incorporates a hand operated pump, check valves, a liquid reservoir and five feet of hose with a disconnect. All components are at- tached to a base plate for stability and ease of operation. Additional components required for spheroid inflation are sphere wrenches and inflation needles, which vary with spheroid manufacturers. Inflation needles are designed to attach to the quick disconnect furnished on the end of the inflation hose.
