Product information "HI96750 Potassium 0.0 - 10.0 mg/l (LR) - Photometer mobile"
Certified calibration and verification standards
BEPS (Battery Error Prevention System)
Potassium as a chemical element is commonly found in nature. It is present in soil and drinking water and is also an essential element for the growth of plants and animals.
Potassium concentration is important in determining the quality of soil in many greenhouse, agriculture and horticulture applications. Potassium salts are also a common component of fertilizers.
The HI 96750 measures the potassium (K) content in water samples in the 0.0 to
10.0 mg/L (ppm) for low range and 10 to 100 mg/L (ppm) for medium range. The
HI 96750 uses the Tetraphenylborate Method. The reaction between potassium and reagents causes turbidity in the sample.
HI 96750 uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell.
HI 96750 is supplied with sample cuvettes with caps (2), 9V battery and instruction manual.
