The LPM 630 is designed to measure a wide variety of physical parameters such as pressure or acceleration. The anodized aluminum housing is screwed on the chrome plated front end which comes with a pair of locking nuts for convenient clamping on the mounting bracket. The gaging tip is made of hi-tensile 17.4 PH stainless steel in order to match the gaged part hardness wherever necessary. Two basic models are available: the ± 30 gram unit able to operate in both tension and compression and the 0-60 gram unit which is compression only.
