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

Description

LAQUAtwin K-11 Pocket Potassium Ion Meter is designed for direct potassium ion testing from very small sample volumes, making it a practical choice for portable testing and routine measurement work. This compact meter measures from just 0.3 mL of sample, or 0.05 mL when used with Sampling Sheet B, helping reduce sample waste while supporting convenient day-to-day use. Its pocket-sized format and direct measurement capability make it suitable where quick testing and small sample volume handling are important.

This model provides a potassium measurement range of 4 to 9900 ppm, mg/L, 0.1 to 250 mmol/L, and 2 to 5000 kg/10a, supporting broad routine testing requirements in a compact format. It supports up to 2 calibration points with auto standard recognition for 150 and 2000 ppm potassium by default, along with changeable high and low calibration values for more flexible setup. Multiplication compensation from 0.01 to 9.90 helps support adjusted concentration handling, while temperature and mV display, temperature calibration, auto hold, auto stable mode, low battery indication, and automatic power off support user-friendly operation. With IP67 dust and waterproof protection, replaceable sensor design, backlit monochrome LCD, and approximately 400 hours of battery life without backlight, LAQUAtwin K-11 is well suited for reliable direct potassium ion testing.
