Marine Low Range Nitrate Checker HC - HI781
The Hanna Marine Low Range Nitrate Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Marine Nitrate Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
- Compact, Portable Design
- Built-in Timer
- Saltwater Compatible

Flat Tip pH Electrode for Skin and Surfaces with Screw Connector – HI1413S/50
The HI1413S/50 is a glass body, single reference junction pH electrode made with low temperature glass and a screw connector. This electrode has a unique open junction design in which there is a viscolene (hard gel) electrolyte layer that is free of silver chloride (AgCl) between the sample to be measured and the internal reference cell. The open junction design resists clogging and the probe's flat tip makes it ideal for pH measurements on surfaces such as skin, leather, agar plates, and paper.
