pH and Temperature Meter AZ Instruments AZ 8692

The AZ Instruments AZ 8692 pH and Temperature Meter is a portable device for measuring acidity (pH) and temperature in liquids. It provides direct digital pH readings and simultaneous temperature monitoring on a clear display, making it suitable for laboratory bench work, field sampling, educational demonstrations, aquaculture monitoring and general water quality control. The instrument accepts a probe input for interchangeable electrodes and is designed for practical, routine measurements where portability and straightforward operation are required.

Advantages

This meter combines pH measurement and temperature sensing in a single portable unit, reducing the need to carry separate instruments. The clear digital readout and simple controls make it easy to operate for both experienced technicians and students. Interchangeable probe compatibility and a probe input allow flexible use with different electrode types. The compact form factor supports field use while retaining features useful for bench-top tasks.

Suitable for

• Laboratory pH testing and routine sample analysis
• Environmental and water quality monitoring in rivers, lakes and wells
• Aquaculture and fish farming water control
• Educational laboratories and practical demonstrations
• Field sampling and mobile testing tasks

Key specifications

• Measurement functions: pH and temperature
• Display: digital readout showing pH value and temperature
• Probe input for external pH electrode and temperature sensor
• Portable handheld design suitable for field and bench use
• Power: battery-operated for mobile measurements

How to use

Install a compatible pH electrode into the instrument’s probe input and power on the meter. Calibrate the pH channel using standard buffer solutions according to laboratory practice before measurements. Rinse the electrode with distilled or deionized water between samples to avoid cross-contamination. Immerse the probe in the sample until readings stabilize, then record the pH and temperature values shown on the display. After use, clean the electrode following the manufacturer’s recommendations and store it in appropriate storage solution if required.

Usage recommendations

For reliable results, perform regular calibration with fresh buffer solutions, keep the electrode clean and properly stored, and allow the probe to thermally equilibrate in the sample for accurate temperature-compensated pH readings.
