The <strong>LaCoste</strong> and <strong>Romberg</strong> gravity meter is made of metal parts.<br />
It is far more rugged than meters made of fused quartz glass.<br />
Because the thermal expansion and contraction of metals are generally<br />
greater than quartz, the L and R meters must be accurately<br />
thermostated. Since metals creep when thermally expanded or<br />
contracted, it is best to maintain the L and R meters at their constant<br />
thermostated temperature whenever practical.<br />
The Model G meters have a worldwide range without resetting.<br />
The Model D meters normally have a range of 200 milligals and a<br />
reset that allows them to operate any place on earth.<br />
