This document is an instruction manual for the HI 93726 Nickel Concentration Tester, describing the features, characteristics, and maintenance requirements of the instrument.
The Hanna Instruments HI 93726 is a handheld instrument designed to measure nickel concentrations in water and wastewater samples within a range of 0.00 to 7.00 g/L. It utilizes an exclusive positive-locking system for cuvet placement and employs the photometric method with specific reagents that cause a blue tint in the sample upon reaction.
The document details the preliminary examination, description of components, display codes, and step-by-step measurement procedures. It also covers specifications such as accuracy (+/- 4% of reading), environmental operating conditions (0 to 50°C), and battery requirements (1 x 9V). Additionally, it lists potential interferences like copper and provides tips for accurate measurements.
