Product Description
LIGHT LABS is proud to offer the Ohaus Explorer™ EXR125 Semi-Micro Balance (Cat # EXR125) — the newest generation of Ohaus's industry-leading Explorer Semi-Micro Balance series, delivering 5-place weighing precision (0.01 mg readability) at a 120 g capacity with a sweeping set of upgrades over the previous EX125 generation. Completely re-engineered from the ground up, the EXR125 features an intuitive 7-inch glass touchscreen display, digital leveling assistance, USB-C connectivity, a chemical-protective design, and a ventilated stainless steel weighing pan — establishing a new benchmark for laboratory semi-micro balance performance, ease of use, and data management.
The EXR125 is powered by Ohaus's proven digital weighing cell technology with a reliable internal environment sensor suite and built-in AutoCal™ automatic internal calibration — ensuring the balance maintains weighing accuracy across changing laboratory temperature conditions without operator intervention. The digital leveling system provides real-time feedback on the balance's level status directly on the touchscreen, making setup and re-leveling faster and more reliable than conventional bubble level systems. A complete suite of communication interfaces — USB Host (Type A x2), USB Device (Type C x1), Ethernet (RJ45), and RS232 — provides seamless connectivity to laboratory information management systems, printers, and computers.
LIGHT LABS is your trusted source for Ohaus laboratory balances and weighing equipment, distributed by Accuris Instruments.
KEY FEATURES
- 5-place weighing precision: 120 g capacity x 0.01 mg (0.00001 g) readability — the industry standard for semi-micro analytical weighing
- Next-generation 7-inch glass touchscreen display — intuitive, bright, and highly responsive; a significant upgrade from the 5.7-inch resistive touchscreen of the previous EX125 generation
- AutoCal™ automatic internal calibration — self-calibrates when the balance detects a temperature change sufficient to affect accuracy, ensuring consistently accurate measurements without manual calibration
- Digital leveling assistance — real-time leveling feedback on the touchscreen eliminates guesswork from balance setup and repositioning
- Ventilated weighing pan — promotes air circulation around the sample to reduce drafts and improve weighing stability
- Chemical-protective design — materials and construction protect against common laboratory chemical splashes and vapors
- Effortless installation — simplified setup with guided on-screen instructions for quick out-of-box deployment
- Full connectivity: USB Host (Type A) x2, USB Device (Type C) x1, Ethernet (RJ45) x1, RS232 x1
- Simplified data management — easy export of weighing data to computers, LIMS, and laboratory printers
- Draftshield included — protects the weighing chamber from air currents during precision weighing
- Pan size: 80 mm (3.14 in.) diameter, stainless steel construction
- GLP/GMP compliant data output with Real Time Clock for regulatory documentation
- Multiple weighing units: grams, kilograms, milligrams, carats, grains, ounces, troy ounces, pennyweight, and more
- Operating temperature range: 10°C to 30°C (50°F to 86°F), ≤85% RH non-condensing
- AC adapter included
