The Model 2EM-60 Differential Cylinder Pressure Tester combines the features of the popular 2E tester and a Master Orifice into one tool. Now you can conveniently check your engine's leakdown rate against a calibrated standard to instantly determine if your engine's cylinder leakage is within the manufacturer's limits. Specifications: Orifice size is .060". precision gauges matched to within +/-2%. Includes 18MM Spark Plug Adapter, 24" pressure hose, and complete instructions. Protective form-fitted hard case included. Factory calibrated. Letter of certification available upon request.
This differential pressure tester has a .060" orifice and is intended for use with engines whose bore diameters exceed 5" per AC43.13 REV 1B. However, Lycoming and Continental service specifications call for the use of a standard tester (with a .040" orifice) even if their engine’s bore diameters exceed 5", and for those engines you must comply with the manufacturer's specifications and use a standard tester such as the 2EM instead of this unit.
All good except coronavirus non-sense. Long phone waits and inability to get in store in Wasilla.
This pressure tester will have a calibration sticker on the unit. If you require the calibration certificate, it must be requested at the time of order and it will be a special order. Contact sales if you require the calibration certificate to set up the special order.
They are similar, they are just made by different manufacturers. These only do leak down tests.
