This document is an instruction manual for the HI 84184 ISE Fluoride Meter, providing information on the correct use of the instrument, technical specifications, functional description, startup process, measurement procedures, etc.
The HI 84184 is a low-cost, easy-to-use fluoride ion selective electrode (ISE) instrument designed to perform automatic analysis with built-in calculations. It utilizes the double standard addition method to determine fluoride concentration in samples such as wine, displaying results immediately in mg/L (ppm). The device features an automatic temperature compensation system and includes a powerful algorithm to analyze electrode response shapes.
