เครื่องวัดค่าฟอสเฟตในน้ำ HANNA HI713-Low Range

Details

The HI713 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphate. Phosphate is a common food additive that enhances flavor and acts as a buffering agent. Important for growth and development
of plant roots, phosphate is also present in fertilizers. However, high concentrations of phosphates are detrimental to the environment; for this reason, it is closely monitored in natural and municipal waters. Designed as a more accurate alternative
to chemical test kits, the HI713 provides quick, accurate results in a few easy steps.

Features at-a-glance:

Easier to use and more accurate than chemical test kits
Dedicated to a single parameter
Small size, big convenience
Ideal for: Water Quality, Aquaculture, Education, Agriculture
