Great info Could use an oil type recommendation but info matches NIST. Use this for PT and Bitzer for oil, Bitzer has weird PT data.
Love this app, very simple to use. It does hang up sometimes, must restart or update, otherwise troublefree. Developer was very responsive to concerns
Excellent App Easy to use simplistic interface. If your in the trade this is an excellent resource to have. Can't beat the price either. Recommended: Yes!
