Ohaus Precision Balance EXR4202 with 7" Color Touchscreen and USB/Ethernet Connectivity

The Ohaus Precision Balance EXR4202 is a high-performance laboratory balance designed for accurate weighing tasks in biotechnology, molecular diagnostics, and bioprocessing environments. Featuring a maximum capacity of 4200 g and a readability of 0.01 g, this balance supports critical measurements such as basic weighing, parts counting, check weighing, percent weighing, totalization, formulation, and density determination—making it versatile and essential for biomanufacturing workflows.

Key technical features include a 7-inch TFT 16.7M color touchscreen with glass overlay, providing intuitive operation and clear data visualization critical in research and clinical diagnostics. The balance comes with a stainless steel 316 weighing pan (201 mm x 178 mm) and an anti-static glass draftshield to ensure stable measurements in varying lab conditions.

Connectivity options are comprehensive for seamless integration into laboratory information management systems (LIMS) and data acquisition platforms, including:

Additional design features beneficial for laboratory precision and compliance include Time Synchronization via NTP, HID support for driver-free computer connections, and four-level user management with an internal log capacity of 100,000 entries, facilitating traceability in regulated environments.

The balance operates on a wide AC input range (100–240 VAC, 50–60 Hz) and features AutoCal™ automatic internal calibration, ensuring consistent precision without manual intervention. The device supports over 20 units of measurement, including grams, ounces, carats, ticals, and others, catering to diverse biotechnological and clinical applications.

Designed for stable operation within 10°C to 30°C and 80% relative humidity, the EXR4202 includes a stabilization time of 1 second, repeatability of 0.01 g, and linearity within ±0.02 g, which are critical for reproducible molecular cloning and synthetic biology research operations.

This analytical precision balance is ideal for biotechnology labs requiring meticulous weight measurements integral to gene editing experiments, biopharmaceutical production pipelines, and formulation processes in synthetic biology. Its robust metal housing and anti-static features enhance durability and measurement integrity in demanding lab environments.
