Pocket fluoride meter LAQUAtwin F-11 allows testing fluoride in municipal drinking water, ground and well water.
Measure fluoride instantly and use it for filtration system efficiency and lifetime control, pure water and reverse osmosis applications, semiconductor industry, industrial and pharmaceutical water.
- Measure from a drop of sample as little as 0.3 ml.
- Features HORIBA unique flat sensor technology (Fluoride Ion Selective Electrode)
- Ideal to measure instantly liquid and solid samples anywhere in the field or in a lab.
- Measurement range from 0.1 to 990 mg/L (ppm)
- 2 calibration points (1 & 10 ppm) for extra precision in measurement
- Resolution ±0.1 ppm up to 10 ppm / ±1 ppm up to 100 ppm / ±10 ppm for range above 100 ppm
- Precision ±2%
- Replaceable sensor
- Calibrate this Fluoride F-11 meter regularly with Fluoride Calibration Solution at 1 and 10 ppm (14 ml solution bottles included with the meter).
- Includes ionic strength adjuster solution TISAB (14 ml)
- HORIBA LAQUAtwin meter F-11 is fully waterproof (IP-67) and can deliver instant results, which makes it a perfect meter for easy and quick field-testing. The wide measurement range allows to measure most samples directly without having to do a dilution or filtration.
This meter includes: plastic case • 1 & 10 ppm calibration solutions (14ml each), plus 1x TISAB solution (14 ml) • 2 x CR2032 batteries • dropper • instruction and quick manuals.
