Hanna HI83141-1 Analog pH/mV/°C meter

Hanna HI83141-1 Analog pH/mV/°C Meter with HI1230B Electrode – Reliable and Easy-to-Use pH Measurement

The Hanna HI83141-1 Analog pH/mV/°C meter  is a compact, battery-powered analog pH, mV (ORP), and temperature meter, designed for users who value precision, portability, and simplicity. Featuring a robust PEI-body pH electrode, automatic temperature compensation, and long battery life, this instrument is ideal for both field and laboratory use.

Key Features

• 3-in-1 Measurement: pH, mV, and Temperature
  Simultaneously monitor pH, mV (ORP or ISE applications), and temperature, making it versatile for a range of analytical and process control tasks.

• Manual Two-Point Calibration
  Fine-tune measurement accuracy using the front-panel calibration trimmers. Supports two-point manual pH calibration for flexible control.

• Automatic Temperature Compensation (ATC)
  Ensures reliable pH readings between 0 and 70°C using the included stainless steel temperature probe.

• Durable PEI-Body pH Electrode
  Includes the HI1230B double-junction pH electrode with a 1-meter cable and BNC connector—ideal for routine, general-purpose applications.

• Compact and Rugged Design
  Lightweight and portable with a sturdy casing, perfect for field sampling or benchtop use in challenging environments.

• Battery-Powered Operation with Auto-Off
  Up to 100 hours of continuous use on a single 9V battery with an auto shut-off feature after 8 minutes of inactivity to conserve power.
