Product Description

The Labmart PH-016 Bench pH Meter is a laboratory tabletop instrument designed for accurate measurement of pH, ORP/mV and temperature in liquid samples. It features a 4-digit LCD display, high input impedance, manual two-point calibration and temperature compensation, making it suitable for routine laboratory and quality-control testing.

Product Overview

The PH-016 Bench pH Meter is a benchtop electrochemical measurement instrument for laboratory determination of acidity/alkalinity, electrode potential and temperature. In addition to conventional pH measurement, it can function as an mV meter for electrode-potential measurements.

The instrument uses a high-input-impedance measurement circuit and provides temperature information through a dedicated temperature probe. Its front-panel controls allow convenient selection of measurement functions and calibration.

Key Features and Benefits

  • pH Measurement: Measures pH from 0.00 to 14.00 for routine acidic, neutral and alkaline sample testing.
  • ORP/mV Measurement: Provides a ±1999 mV measurement range for electrode-potential applications.
  • Temperature Measurement: Measures sample temperature from 0°C to 100°C.
  • 0.01 pH Resolution: Enables detailed pH readings for laboratory QC work.
  • Manual Two-Point Calibration: Allows calibration using two appropriate pH reference points.
  • Temperature Compensation: Helps account for temperature effects during measurement.
  • 4-Digit LCD Display: Provides clear digital measurement readings.
  • High Input Impedance: Suitable for electrochemical measurements involving pH and ion-selective electrodes.
  • Bench-Top Configuration: Designed for stable placement on laboratory workstations.
