4-in-1 Hydrogen, pH, ORP, and Temperature Water Tester Pen

Ensure your drinking water and aquatic systems are optimal with this hydrogen water tester. Designed for comprehensive water diagnostics, this digital 4-in-1 testing pen measures dissolved hydrogen (H2), pH levels, Oxidation-Reduction Potential (ORP), and fluid temperature simultaneously. Featuring a highly sensitive multi-sensor probe and a clear backlit LCD screen, it delivers real-time readings to track antioxidant properties and water quality. Equipped with Automatic Temperature Compensation (ATC) and an IP67 waterproof housing, it provides reliable, laboratory-grade testing for hydrogen-rich water generators, aquariums, pools, and hydroponics.

Key Features

• 4-in-1 Water Diagnostics: Measures dissolved hydrogen (H2), pH acidity/alkalinity, ORP millivolts, and temperature in one device.

• Backlit Digital LCD Screen: Clear digital display simultaneously shows active parameter values and temperature readouts.

• Automatic Temperature Compensation (ATC): Internal thermal sensor adjusts for temperature fluctuations to maintain accuracy.

• IP67 Waterproof Housing: Durable, sealed body protects internal electronics against accidental drops into water tanks or test jars.

Why Choose Our 4-in-1 Hydrogen, pH, ORP, and Temperature Water Tester Pen Testing multiple water parameters traditionally requires several bulkier meters or inaccurate chemical test strips. Our hydrogen water tester combines four vital diagnostic functions into a single pocket-sized pen, delivering instant digital clarity for health-conscious individuals and aquarists alike.

Perfect For

• Testing hydrogen-rich water bottles, ionizers, hydrogen generators, and alkaline drinking water.

• Monitoring freshwater aquariums, reef tanks, aquaculture setups, hydroponic nutrient tanks, pools, and spas.
