Hanna HI736-11 – Phosphorus Ultra Low Range Checker HC
The Hanna HI736-11 Phosphorus Ultra Low Range is a high-precision handheld colorimeter designed to measure ultra-low levels of phosphorus in water samples. Specifically engineered for sensitive environments such as aquatic ecosystems, laboratory research, and nutrient monitoring, this Checker HC provides laboratory-grade accuracy in a compact and portable design.
Unlike conventional test kits that rely on visual interpretation, the HI736-11 delivers digital readings in parts per billion (ppb), reducing human error and significantly improving testing reliability.
Key Features
Ultra-Low Detection Capability
The device accurately measures phosphorus levels in the range of 0 to 200 ppb, with 1 ppb resolution and ±5 ppb ±5% accuracy at 25°C. This makes it ideal for applications requiring trace-level monitoring.Standardized Testing Method
The HI736-11 uses an adaptation of the Ascorbic Acid Method, a well-established technique for phosphorus detection. In this method, a color reaction occurs, and the device measures the intensity of the resulting blue tint to quantify the phosphorus content.Compact and Portable
Because of its small size and lightweight design, the HI736-11 is easy to carry for field testing while still delivering precise results.Fast and User-Friendly
With a single-button operation and a digital display, users can perform accurate tests in just a few simple steps. Additionally, the device shuts off automatically after two minutes of inactivity to conserve battery life.
