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.
- 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
