This document describes the features and specifications of the GPC-200 Electronic Specific Gravity Meter produced by Protaidea Testing Instruments Co., Ltd.
The GPC-200 is a digital straight‑read specific gravity meter designed for precise density measurement in laboratory and industrial settings. It offers built‑in automatic calibration weights, self‑calibration, single‑key auto‑calibration, and automatic environmental correction to ensure reliable results.
Key features include a weighing capacity of 200 g, a specific gravity resolution of 0.001 g/cm³, accuracy of 0.01 g, and unit conversion among g, mg, %, ct, GN, TL, D, pc, and Lb. The instrument comes with RS‑232 interface, operation manual, 200 g weight, thermometer, and accessories such as a round glass tank, clip, support stand, and measuring table. Power is supplied via a transformer (AC 110/220 V, 50/60 Hz, 11 VA) and it can test densities both greater than and less than 1 with temperature compensation. This manual is written in Chinese.
