Adam Core CQT [CQT 1501] Portable Compact Balances With External Calibration, 1500g x 0.1g. The Adam Equipment CQT 1501 1500g Core Digital LCD Portable Compact Balance offers outstanding value, providing easy operation and a portable solution for many basic precision weighing tasks. An innovative stackable design saves space, and it can easily be stored in school supply cupboards and prep rooms until needed, ideal for busy science classrooms or laboratory environments. Offering precision results, the Core balance is suitable for weighing compounds in science classrooms, samples at a field lab, ingredients in food labs and specimens at veterinary offices. The Core operates smoothly and looks sleek, but it's created for utility. The ABS housing withstands field, classroom and laboratory environments, and the stainless steel pan is removable, making it simple to clean. The ShockProtect safeguards the load cell, so it can handle overloads without damage. To help prevent theft, a built-in security slot accommodates an optional Kensington-type lock and cable. Portability is not an issue with the Core, as the balance operates by battery or AC adapter. A convenient weigh-below hook facilitates below-balance weighing for density and specific gravity measurements.
