HI98127 pHep®4 waterproof pH/Temperature Tester

This portable tester measures pH in a range of -2.0 to 16.0 with a resolution of 0.1 pH and Temperature (°C/°F).

Note:It is normal for salt deposits to form on the outside of electrode cap or on cap/rim. This is dried bottling solution from inside cap. Wipe off with soft tissue and rubbing alcohol or use tap water.

Key features...

• Replaceable pH electrode with renewable cloth junction.
• Stability and ATC (automatic temperature compensation) indicators.
• Switchable between °C and °F.
• HOLD function temporarily holds display so you can view a single reading.
• BEPS (Battery Error Prevention System)
• Battery % displayed at startup
• Automatic 1 or 2 point calibration.
• Meter is waterproof and it floats.
• Dual line LCD displays pH and temperature.
• Unique renewable cloth electrode junction - when clogged, simply pull a short length out, snip off old section, and expose fresh material.

Details

The pHep®4 and pHep®5 testers are for users that require the greatest accuracy and features while staying economical. The pHep®4 has a 0.1 pH resolution and pHep®5 reads up to 0.01 pH. 

Both models have BEPS, which prevents taking a reading due to low battery as well as user-selectable automatic shut-off, replaceable pH electrode cartridge, stability indicator and automatic calibration.

Features at-a-glance

• Waterproof and designed to float
• Automatic Temperature Compensation
• HOLD button to freeze readings on the display
• BEPS Alerts the user of low battery power that could adversely affect readings
