HM Digital (PH-80) HydroTester Water pH Temperature Tester Meter Pen

Product details

HM Digital (PH-80) HydroTester Water pH Temperature Tester Meter Pen is an in-tank and bench-friendly digital meter pen designed to measure water pH and display temperature at the same time. It’s a practical tool for aquarium and reef keepers who want to quickly check water chemistry during routine testing, water changes, or troubleshooting. Because it includes automatic temperature compensation and digital calibration, it can help you take more consistent readings when testing different water temperatures. The unit is water resistant and uses an included storage cap and buffer solution for maintaining calibration readiness.

Features:

• Measures pH and temperature in one device
• Automatic Temperature Compensation (ATC) for more consistent pH readings across temperatures
• One-touch automatic digital calibration with selectable pH 4.0, 7.0, or 10.0
• Large LCD display for easier reading of results
• Water resistant housing for safer day-to-day use around aquarium water
• Auto-off function plus data-hold and a low-battery indicator
• Factory calibrated and includes storage solution in a sponge-embedded cap
• Uses a glass sensor for pH measurement with associated reference components
