Alternative to the Chandler 5550
Summary. The Coretest HPHT Rheometer is a same-class alternative to the Chandler 5550: both are 2000 psi / 500 F concentric-cylinder HPHT instruments in Hastelloy C276. On published specs the Coretest unit reaches a lower minimum shear rate (0.00004 s-1 vs 0.17 s-1) and a wider shear-stress range (to 15000 vs 4900 dyn/cm2). The Chandler 5550 is the more mature, field-proven product.
