brief introduction

The NP-1D Multi link Room Temperature Expansion Tester is a precision measuring instrument used to detect the expansion changes of rock cores or expansive soils under normal temperature and pressure conditions. It provides a method for determining the expansion characteristics of rock cores or bentonite, optimizing drilling fluids, and evaluating the stability of various additives on rock cores or bentonite.

Instrument characteristics

Adopting a precision mechanical pointer measuring device, the indication is accurate, the reading is intuitive, and the use is convenient. The machine adopts a four link structure, which can conduct multiple experiments or parallel experiments of the same experiment simultaneously, obtaining multiple data at once, greatly improving work efficiency.
