Hanna pH/Temperature Tester with 0.01 pH Resolution - pHep®5 HI98128

The pHep®5 HI98128 is a handheld pH and temperature tester designed to provide laboratory-grade pH measurements in a compact, waterproof pocket instrument. It measures pH with 0.01 resolution and automatic temperature compensation, provides automatic one-, two- or three-point calibration to selectable buffer sets, and is supplied with a replaceable HI73127 pH electrode. Primary use cases include field and on-site pH and temperature testing where a rugged, portable, and accurate instrument is required.

Key Features:

• pH resolution: 0.01 pH
• pH accuracy: ±0.05 pH (@ 20°C)
• pH range: -2.00 to 16.00 pH
• Temperature range: -5.0 to 60.0°C (23.0 to 140.0°F); temp resolution 0.1°C/0.1°F; temp accuracy ±0.5°C/±1°F
• Automatic one-, two-, or three-point pH calibration to two selectable buffer sets (4.01/7.01/10.01 or 4.01/6.86/9.18)
