Key Features:

Reliable pH Accuracy
Measures pH with a 0.1 resolution and ±0.1 accuracy, making it ideal for general-purpose water testing across various industries.

Replaceable Electrode with Cloth Junction
The HI73127 snap-in electrode features a stainless steel round connector with no fragile pins. Its extractable cloth junction allows users to renew the junction by simply pulling it out ⅛”, clearing clogs and restoring fast response times.

Automatic Calibration
One or two-point automatic calibration with two selectable buffer sets (4.01, 7.01, 10.01 or 4.01, 6.86, 9.18) ensures precision and user convenience.

Smart Design & Functionality:

• Waterproof Housing: Designed to float if accidentally dropped in a tank or container
• Expanded pH Range: Measures from -2.0 to 16.0 pH
• Automatic Temperature Compensation: Ensures accurate readings regardless of environmental changes
• Stability Indicator: Clock icon disappears when a stable reading is achieved
• Hold Function: Freezes the display to make note-taking easy
• BEPS (Battery Error Prevention System): Automatically powers off if battery level is too low for reliable readings
• Auto-Off Feature: Shuts down after 8 minutes of inactivity to conserve battery life
