Portable optical pH meter

The FluoMini pH portable optical pH meter is based on the fiber optic spectroscopy measurement principle developed by Sendot for pH measurement. Unlike traditional electrode measurement principles, this measuring instrument is insensitive to drift height and requires almost no calibration of the sensor; The ion strength and temperature have almost no effect on the measurement, therefore, they can also be applied to low conductivity solutions. This instrument can be an ideal equipment for laboratory and field applications.

Main features

Using the principle of fiber optic spectroscopy, the measurement is accurate and drift free

Can be directly used for soil solution measurement or hydroponic solution measurement

Unique non-invasive measurement design, the probe can measure without the need to insert a solution

The sensor is equipped with a metal protective cover, which is sturdy, durable, and easy to maintain

Large data storage capacity, capable of short-term or long-term continuous monitoring and recording

Basic configuration

Instrument host; Fiber optic pH sensor (with metal protective cover); 2-meter USB cable; Software and manual USB drive; A suitcase.
