Review on Lang Tools TU 15 Diesel Compression by Brian Delgado

Bought to do a compression test on a 2005 Cummins. It comes with a high quality blown plastic case. Some reviews said that the pressure gauge that came with the unit was not calibrated to zero (probably due to a shipping collision). The meter I received arrived in perfect condition with the meter still zero calibrated, but as an upgrade at the time of ordering I purchased a better quality glycerin meter from Amazon (Winters PFQ Series Dual Scale 304 Stainless Steel Gauge, liquid filled, with brass internals, 0-1000 psi). longer lifetime. Be sure to tighten all fittings on this tool when changing from a factory gauge to an upgraded gauge. All of the fittings on mine took about a half turn to tighten. I wish the manufacturer had used this sensor from the start, I would happily pay more for the tool if it came with an upgraded sensor.
