Ohaus Aquasearcher AB23PH-F Benchtop pH Meter with ST322 pH Electrode

The Ohaus Aquasearcher AB23PH Benchtop pH Meter is a simple-to-use pH measurement instrument designed for easy and straightforward pH and ORP monitoring in laboratory, educational, and quality control environments. Featuring an intuitive design with six instructional menu buttons and a large 5-inch segment LCD display with backlight, the AB23PH simplifies operation by presenting complete measurement information in a clear, easy-to-read format that allows users to monitor results from a distance. The meter measures pH, oxidation-reduction potential (ORP), and temperature with auto buffer recognition and 3-point calibration capability that ensures reliable calibration results while minimizing operator training requirements and reducing calibration errors. An electrode condition icon provides visual feedback on probe status, alerting users when electrode maintenance or replacement may be required to maintain measurement accuracy. With automatic temperature compensation integrated into the measurement process, the AB23PH delivers consistent, accurate pH readings across varying sample temperatures without requiring manual correction calculations.

Engineered for space efficiency and experimental flexibility, the AB23PH features a compact standalone electrode holder with a small base footprint that increases flexibility for routine experiments and makes it a perfect space-saving bench meter for crowded laboratory workstations. The meter's 99-item memory stores pH measurements for efficient data documentation and collection, supporting basic record-keeping requirements in quality control and educational settings. Constructed with durable ABS housing and reliable mechanical keys that withstand daily laboratory use, the AB23PH operates on included AC adapter for continuous, uninterrupted operation without concern for battery replacement. Meeting EN 61326-1 electromagnetic safety standards and FCC electromagnetic compatibility requirements, the Aquasearcher AB23PH combines straightforward operation with reliable performance, making it an ideal pH measurement solution for educational laboratories, routine quality control testing, water quality analysis, food and beverage production, basic research applications, and any environment requiring simple, accurate, and space-efficient pH and ORP measurement capabilities without the complexity of advanced multi-parameter instruments.

Features of Ohaus AB23PH-F pH Meter:

  • Comprehensive 1 - Year Warranty and Quality Assurance - Backed by manufacturer warranty ensuring reliable performance and quality construction for long-term pH measurement applications in laboratory and educational environments.
  • Intuitive Six-Button Interface - Six instructional menu buttons provide straightforward, easy-to-understand operation with minimal training required, ideal for multi-user environments and educational settings.
  • Large 5-Inch Backlit LCD Display - Bright segment LCD with backlight displays complete measurement information in clear, easy-to-read format, enabling result monitoring from a distance for convenient operation.
  • Auto Buffer Recognition - Automatic buffer recognition with 3-point calibration capability ensures reliable calibration results while simplifying procedures and reducing operator error in pH measurement.
  • Electrode Condition Icon - Visual electrode status indicator provides real-time feedback on probe condition, alerting users when maintenance or replacement is needed to maintain measurement accuracy.
  • Automatic Temperature Compensation - Integrated ATC delivers consistent, accurate pH readings across varying sample temperatures without requiring manual correction calculations, ensuring measurement reliability.
  • 99-Item Measurement Memory - Built-in data storage for 99 pH measurements ensures efficient data collection and documentation for basic record-keeping in quality control and educational applications.
  • Compact Standalone Electrode Holder - Space-saving standalone holder with small base footprint increases experimental flexibility and fits ideally in crowded laboratory workstations without requiring extensive bench space.
  • Durable ABS Construction - Robust ABS housing with reliable mechanical keys withstands daily laboratory use, protecting internal electronics in educational and industrial environments.
  • Continuous AC Power Operation - Operates on included AC adapter for uninterrupted continuous operation without concern for battery replacement, ensuring reliable performance during extended measurement sessions.

Applications for Ohaus AB23PH-F pH Meter:

  • Food and Beverage Production: pH measurement of food products, ingredients, beverages, and processing solutions for basic quality control, shelf-life prediction, and food safety verification in production facilities.
  • Basic Quality Control Testing: Routine pH verification of products, materials, and solutions in manufacturing quality control laboratories where simple, reliable pH measurement satisfies testing requirements without advanced features.
  • Water Quality Analysis: pH and ORP monitoring of drinking water, wastewater, aquarium water, and environmental samples for basic water quality assessment in field stations and testing laboratories.
  • Agricultural and Horticultural Testing: Soil pH testing, nutrient solution monitoring, and hydroponic system management for agricultural research, commercial growing operations, and horticultural applications.
  • Chemical Laboratory Operations: General pH and ORP measurement for solution preparation, simple chemical analysis, and basic laboratory procedures where straightforward pH monitoring is required.
  • Small Business and Workshop Applications: Space-efficient pH testing for small-scale production, craft brewing, artisan food production, and workshop environments with limited bench space.

Ohaus AB23PH-F Kit Includes:

AQUASEARCHER AB23PH Benchtop Meter, Stand-Alone Electrode Holder, ST322 pH Electrode, pH Buffer Mini Kits (4 × 50 ml).

Key Differences Between AB23EC and AB23PH Benchtop Meters

1. Measurement Parameters:

  • AB23PH: Measures pH, oxidation-reduction potential (ORP), and temperature - designed specifically for acidity/alkalinity and redox potential measurements using pH electrodes.
  • AB23EC: Measures conductivity, total dissolved solids (TDS), salinity, and temperature - designed for ionic content and dissolved solids measurements using conductivity probes.

2. Calibration and Compensation Features:

  • AB23PH: Features auto buffer recognition with 3-point pH calibration capability and electrode condition icon for pH electrode status monitoring.
  • AB23EC: Features both automatic and manual temperature compensation modes with automatic and manual endpoint functions, but does not include buffer recognition (not applicable to conductivity measurements).

In Summary: Choose the AB23PH for measuring acidity/alkalinity (pH) and redox potential (ORP), or choose the AB23EC for measuring electrical conductivity, dissolved solids content, and salinity. Both meters share the same user-friendly design with 6-button interface, 5-inch backlit display, 99-item memory, and compact standalone holder.
