16 in 1 Water Testing for Pools, Fish Tanks Drinking Water TDS Pen

[Comprehensive 4-Parameter Water Analysis]

Monitor your aquarium ecosystem with precision using this complete testing kit that covers the four most critical water quality indicators. The triple-function dip strips simultaneously measure pH levels, carbonate alkalinity, and general hardness-essential parameters for maintaining healthy fish, thriving plants, and balanced biological filtration. The included digital TDS pen adds total dissolved solids measurement, giving you a complete picture of water purity that strips alone cannot provide.

[Instant Dip-Strip Convenience]

Simply immerse one test strip into your aquarium water for 2 seconds, then compare the color-changing pads against the included reference chart-results appear in 30 seconds with no mixing, waiting, or messy reagents. The color-coded pads resist bleeding between test zones, ensuring accurate readings for each parameter independently. Perfect for quick daily checks, post-water-change verification, or troubleshooting sudden fish behavior changes.

[Precision Digital TDS Pen]

The compact 3 cm x 15.4 cm TDS meter delivers laboratory-accurate total dissolved solids readings with a single button press. The waterproof probe tip withstands submersion in tanks, sumps, and buckets, while the auto-calibration chip maintains accuracy through months of regular use. The large LCD display shows readings in ppm with automatic temperature compensation, eliminating guesswork from water change decisions and filter maintenance schedules.

[Freshwater & Saltwater Versatility]

Calibrated for tropical community tanks, goldfish ponds, marine reef systems, and brackish setups alike. The pH pad spans the full aquarium-relevant range from acidic to alkaline, while the hardness and alkalinity tests guide proper buffering for species-specific needs. The TDS pen measures from 0-9990 ppm, covering everything from ultra-pure RO/DI water to high-mineral African cichlid conditions.

[Durable PVC Construction & Long Storage]

Both test strips and TDS pen feature rugged PVC housings that resist humidity degradation and accidental drops. The strip vial includes a desiccant cap that preserves reagent freshness for 2 years when sealed between tests, while the TDS pen's automatic shutoff extends battery life through hundreds of measurements. A complete kit that outlasts liquid test kits and provides more parameters than single-purpose meters.
