OHAUS PS251 PS Portable Balance, 250g Capacity, 0.1g Readability, LCD Display

OHAUS PS251 PS Portable Balance — Pocket-Sized 250 g Weighing with LCD Simplicity

Fitting in a jacket pocket or a student's backpack, the OHAUS PS251 PS Portable Balance distills weighing down to its essentials: a 250 g capacity, 0.1 g readability, and a crisp LCD readout powered by two coin-cell batteries. For anyone who needs quick, reliable measurements on the move, this ultra-compact balance removes every unnecessary barrier.

Key Features

• Ultra-Compact Form Factor: At just 97 mm × 22 mm × 71 mm, the PS251 slips into a pocket, tool kit, or backpack without bulk — genuinely portable in the most literal sense.
• 250 g Capacity at 0.1 g Readability: Accurate enough for lab-style measurements in educational, jewelry, and field contexts that do not require sub-gram precision.
• Two-Button Operation: Minimal interface reduces operator errors and eliminates any learning curve, making the balance accessible to first-time users.
• Protective Sliding Pan Cover: ABS cover protects the pan surface during transport, keeping measurement surfaces clean and undamaged between uses.
• CR2032 Battery Power: Two included lithium coin cells provide approximately 34 hours of operation — suitable for intermittent daily use over extended periods.
• Multiple Weight Units: Switches between grams, ounces, troy ounces, and pennyweight, covering general scientific and precious-metal applications.
• Auto Shut-Off: Prevents battery drain when the balance is left unattended, extending overall service life between battery replacements.

Detailed Overview

The PS251 targets users who need measurement capability without carrying a larger instrument. Its protective sliding pan guard keeps the weighing surface clean when the balance travels in toolboxes, backpacks, or carrying cases. Overload and underload protection — both mechanical and via software — prevent damage if samples exceed the 250 g limit. The balance arrives with batteries installed and ready to use immediately, with no setup or calibration required on first use. Linearity is rated at ±0.1 g, consistent with a 0.1 g readability instrument intended for practical field and educational applications rather than trace-level analytical work. Stabilization within 2 seconds delivers a prompt reading even when samples are placed and removed quickly.

Applications

• Student field assignments and educational activities where portability is paramount
• Jewelry and precious-metal weighing in shop or market settings
• Hobbyist and craft applications requiring convenient gram-level measurement
• Technician tool kits requiring an always-available weight reference
