OHAUS ST300-F Starter 300 pH Portable, 3-Point Calibration, User-Friendly Memory, Long-Lasting Power, High-Precision Portable pH And ORP Meter 

After more than a century of perfecting the art of measurement through our durable weighing products, OHAUS precision is now available in the form of a portable pH meter. This portable meter offers convenience, reliability and durability in one compact design.

Features

  • Rugged IP54 Construction: Dust and splash-resistant ABS housing designed for single-handed field operation and harsh environments.
  • Integrated Desktop Stand: Built-in retractable stand easily converts the portable meter for benchtop laboratory use.
  • Multi-Parameter Capabilities: Measures pH, Oxidation-Reduction Potential (ORP / mV), and Temperature simultaneously.
  • Dual Temperature Compensation: Supports both Automatic Temperature Compensation (ATC) and Manual Temperature Compensation (MTC).
  • 3-Point Calibration: Features auto-buffer recognition for standard calibration groups with real-time status icons on display.
  • On-Board Data Memory: Stores up to 30 measurement readings and saves the last calibration data for quick recall.
  • Dual Endpoint Options: Offers both Auto-Endpoint (holds stable readings automatically) and Manual Endpoint capture modes.
  • High-Resolution Measurement:
  • pH Measuring Range: -2.00 to 20.00 pH (Resolution: 0.01 / 0.001 pH, Accuracy: ±0.01 pH).
  • mV Measuring Range: -2000.00 to +2000.00 mV (Resolution: 0.01 / 1 mV, Accuracy: ±1 mV).
  • Temperature Range: -30.0 °C to 130.0 °C (Resolution: 0.1 °C, Accuracy: ±0.5 °C).
  • Clear LCD Interface: Shows simultaneous parameter readings, battery status, endpoint status, and calibration icons.
  • Standard Connections: BNC electrode connector (impedance >10¹² Ω) and Cinch / NTC 30 kΩ temperature input.
  • Extended Battery Life: Powered by 4 × AAA batteries (LR03) providing over 250 hours of continuous operation.
  • ST320 Gel pH Electrode Included: Comes with a durable 3-in-1 plastic body gel pH electrode with built-in temperature sensing.
  • Field Kit Accessories: Includes an IP54 protection seal set, wrist strap, electrode clip, pH buffer sachets, AAA batteries, and a hard carrying case.
