Hanna Checker Phosphorus ULR HI-736 - Ultra-precise reef test

Hanna HI-736 Ultra-Low Range Phosphate Tester for Reef Aquariums

The Hanna Checker Phosphorus ULR HI-736 (Ultra Low Range) is a portable digital colorimeter designed to measure ultra-low phosphate levels in reef aquariums with exceptional accuracy. This device is essential for maintaining optimal phosphate levels and promoting coral growth while preventing unwanted algae blooms.

Why Measure Ultra-Low Phosphate in Your Reef

Phosphate is one of the most critical nutrients to monitor in a reef aquarium. Even at extremely low concentrations, phosphate can fuel the growth of harmful algae and inhibit coral calcification. Modern reef aquariums aim for near-zero phosphate levels (0.00–0.10 ppm), which necessitates an ultra-precise tester like the HI-736 capable of detecting these minute concentrations.

Main Features

• Ultra-Low Range (ULR) : Specially calibrated to detect the extremely low phosphate levels essential to reefs.
• Exceptional Precision : Ultra-precise digital results impossible to achieve with traditional colorimetric kits
• Simplified Use : One-button operation for fast and reliable testing
• Portable and Convenient : Compact pocket-sized design with automatic shut-off
• Pre-dosed reagents : Ready-to-use reagent sachets for precise and reproducible measurements

Use in 3 Simple Steps

1. Take a water sample from your aquarium using the syringe provided.
2. Add the pre-dosed reagent sachet to the cuvette with the sample
3. Insert the cuvette into the Checker and press the button to get your ultra-precise reading
