Pocket-sized fluoride-ion meter with replaceable lanthanum trifluoride crystal sensor.
3 Years Limited Warranty (2 Years Manufacturer Warranty + Bonus 1 Year Instrument Choice Warranty for the meter. 6 months warranty for the sensor)
Features:
- Micro-Sample Measurement Capabilities: The replaceable sensor, featuring a lanthanum trifluoride crystal, allows measurements in samples as small as 0.3 ml (or 0.1 ml with a sampling sheet).
- Extensive Measurement Range: Covering 0.1 to 990 ppm or mg/L, the meter delivers accurate fluoride ion readings.
- Unmatched Accuracy: With an accuracy of 2% of the actual value, the meter ensures reliable results for your analyses.
- Convenient Two-Point Auto Calibration: Achieve accuracy with two-point calibration, as the meter automatically recognizes and calibrates 1 ppm and 10 ppm fluoride ion standard solutions included in the kit. Customize calibration using other standard solutions that are ten-fold apart in concentration.
- Multiplying Compensation Function: Considering sample dilution in the reading, the meter features a multiplying compensation function to calculate the correct concentration.
- Auto Stable & Auto Hold Measurement Modes: Assisting users record stable readings, the meter displays smiley indicator and can freeze the reading.
- Temperature Calibration: Displaying temperatures up to 50.0 C, the meter allows for temperature correction through its calibration function.
- IP67 Rating: Waterproof and dustproof meter with digital LCD and backlit display
- Complete Package for On-the-Go Fluoride Ion Testing: Each F-11 meter comes with 1ppm and 10ppm fluoride ion standard solutions (14 ml each), TISAB solution (14 ml), 5-ml plastic beaker, batteries, syringe, and 5 sampling sheets.
