Precision water quality testing has never been easier. This pen-type 7-in-1 water quality tester lets you quickly and accurately measure seven essential parameters in one compact, portable device — ideal for aquarium hobbyists, hydroponic growers, pool owners, environmental testing and general water quality checks.

Key Features & Benefits

All-in-One Testing: Measures pH (acidity/alkalinity), TDS (total dissolved solids), EC (electrical conductivity), ORP (oxidation-reduction potential), Salinity, Specific Gravity (S.G) and Temperature — giving you a complete water quality profile in one tool.
Automatic Temperature Compensation (ATC): Built-in ATC adjusts readings for temperature fluctuations, ensuring accurate results across a range of conditions.
Wide Application Use: Perfect for aquariums, hydroponic nutrient solutions, pools, drinking water, spas and other aqueous environments.
Easy Operation: Simple pen-style design makes testing straightforward — just immerse the probe in water and press a button to toggle between measurement modes.
Portable & Durable: Compact and lightweight for convenient field use or lab work; easy to store when not in use.
Multi-Scale Salinity Measurement: Checks salinity levels for both freshwater and saltwater environments — helpful for aquarium and marine tank setups.

Maintaining optimal water quality is critical for healthy aquatic life and plant growth. Whether you’re managing fish tanks or hydroponic systems, unstable pH, excess dissolved solids or improper conductivity can stress aquatic animals or stunt plant roots. This multi-parameter water tester lets you quickly get the data you need to correct imbalances and keep your system thriving.

Who It’s For

Aquarium Owners: Maintain stable conditions for fish, corals and plants.
Hydroponic & Aquaponic Growers: Monitor nutrient solutions and water balance.
Pool and Spa Users: Check salinity and pH levels to ensure safe water.
Home & Lab Testing: Assess drinking water or general water quality with ease.

How It Works

Calibrate: Use the one-touch calibration function to ensure accuracy.
Select Parameter: Press the MODE/CAL button to switch between pH, TDS, EC, ORP, S.G, Salinity and Temperature.
Test: Immerse the probe in the test solution and wait for a stable reading.
Read Results: View clear numerical readouts for each measured water quality factor.
