Ohaus Portable Balance CR221 AM White 220g Toploading Laboratory Scale

Description

Product Overview

The Ohaus CR221 AM portable balance is engineered for scientists, educators, and field technicians who demand accuracy without sacrificing portability. Built with a robust stainless‑steel platform, the balance supports a maximum capacity of 220 grams while delivering a readability of 0.1 gram, ensuring that even the smallest mass changes are captured reliably. Its compact footprint—measuring just five inches by five inches with a height of four inches—allows it to fit comfortably on benchtops, workstations, or even in a field kit. Powered by three AA batteries, the unit provides up to 300 hours of continuous operation, eliminating the need for frequent battery changes during critical experiments. The device features a clear LCD display with backlighting, intuitive tare and zero functions, and a simple one‑button operation that reduces training time and minimizes user error. All components are calibrated to meet ISO 9001 standards, and the balance includes a protective cover to shield the weighing pan from dust and debris when not in use.

Usage

Designed for versatility, the CR221 AM excels in a variety of environments. In academic laboratories, it provides students with a reliable tool for chemistry titrations, physics mass experiments, and biology sample weighing. In industrial settings, technicians use it for quality control checks, component verification, and small‑batch production weighing where precision is essential. Field researchers appreciate its lightweight design and long battery life, allowing them to conduct on‑site analyses of soil samples, water quality testing, and environmental monitoring without the need for a power outlet. The balance’s quick tare function enables rapid resetting between samples, while its spill‑resistant design protects the internal circuitry from accidental liquid exposure. Whether you are measuring reagents, calibrating equipment, or conducting routine inventory checks, the CR221 AM offers a dependable solution that adapts to the demands of both controlled laboratory spaces and rugged field conditions.
