Pocket Fluoride Ion Meter, 0.3 mL Sample Testing with 2-Point Auto Calibration and Backlit LCD

Description

LAQUAtwin F-11 Pocket Fluoride Ion Meter is designed for direct fluoride ion testing from very small sample volumes, making it a practical choice for portable water quality measurement and routine laboratory use. As a pocket-sized fluoride ion meter, it supports convenient on-site testing without the need for bulky bench equipment. The replaceable sensor features a lanthanum trifluoride crystal and allows measurement from just 0.3 mL of sample, or 0.01 mL when used with Sampling Sheet B, helping reduce sample waste while simplifying testing of limited-volume samples.

This compact meter provides a fluoride ion measurement range of 0.1 to 990 ppm, mg/L, with accuracy of ±2% of the actual value. It supports two-point calibration with automatic recognition of 1 ppm and 10 ppm fluoride ion standard solutions, while allowing changeable low and high calibration values for flexible setup. The multiplying compensation function helps account for sample dilution in the reading, and temperature calibration supports more controlled operation. Auto hold and auto stable modes, low battery indication, automatic power off, IP67 water and dustproof protection, and a backlit monochrome LCD make the LAQUAtwin F-11 a user-friendly and reliable solution for direct fluoride ion measurement in the field or laboratory.
