Arizona Instruments ZSP150 Electronic Balance

The Arizona Instrument ZSP150 Electronic Balance is a compact 150 g capacity digital balance with a readability of 0.001 g, designed for precise bench-top mass measurements in laboratory settings. It operates in a single weighing range with a tare of 0–150 g, delivers a repeatability of 0.0015 g and a linearity of ±0.0015 g, and offers a user-selectable stabilization time with adaptive weighing speed and a 200 ms update interval for quick, repeatable results. Connectivity is via a standard RS-232 bidirectional data interface supporting baud rates of 300, 600, 1200, 2400, 4800, 9600 and 19200; a circular 4.5-inch weighing pan is paired with a 6-inch diameter x 3.25-inch high windscreens to shield samples. The enclosure measures 7.5" x 11.25" x 3.25" and weighs roughly 9.5 lb. Power is supplied from 115 V/60 Hz or 230 V inputs, and the instrument is designed for indoor use from 5°C to 40°C with up to 80% RH (decreasing to 50% at the upper end of the temperature range), suitable for laboratory environments up to about 2000 meters altitude and Made in the USA.
