The Hanna HI8314-1 Analog pH/mV/°C meter is a compact, battery-powered analog pH/mV/temperature meter designed for quick and accurate measurements in field or laboratory settings. Equipped with a durable PEI-body pH electrode and a stainless steel temperature probe, this meter is an excellent choice for professionals who value simplicity, precision, and long battery life.

Key Features

• 3-in-1 Measurement
  Simultaneously measures pH, mV (ORP or ISE), and temperature, making it versatile for various testing environments.

• High Precision Analog Readout
  Delivers high resolution and accuracy with a classic analog design—ideal for those who prefer tactile control and direct visualization.

• Manual Two-Point Calibration
  Fine-tune pH readings with two-point calibration using accessible trimmers on the front panel for accurate and repeatable results.

• Automatic Temperature Compensation (ATC)
  Includes HI7669AW temperature probe to ensure accurate pH measurements across a temperature range of 0 to 70°C (32 to 158°F).

• Durable and Portable
  Lightweight and compact with a robust casing for reliable use in the lab, greenhouse, field, or plant floor.

• Automatic Shut-Off
  Conserves battery by powering down after 8 minutes of inactivity—ideal for extended field sessions.
