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

Description

LAQUAtwin Ca-11 Pocket Calcium Ion Meter is designed for direct calcium ion testing from very small sample volumes, making it a practical choice for portable testing and routine laboratory measurement. This compact pocket meter measures calcium ion concentration from just 0.3 mL of sample, or 0.05 mL when used with Sampling Sheet B, helping reduce sample waste while improving convenience during day-to-day use. Its sensor design also supports measurement of viscous liquids, solids, and powder samples, so there is no need for a beaker during calibration or sample testing. Users can place a few drops of standard or sample directly onto the flat sensor for quick and simple measurement.

This model provides a calcium measurement range of 4 to 9900 ppm, mg/L, and 0.1 to 250 mmol/L, supporting broader routine calcium ion analysis in a portable format. It supports up to 2 calibration points with auto standard recognition for 150 and 2000 ppm calcium by default, along with changeable high and low calibration values for more flexible setup. Multiplication compensation from 0.01 to 9.90 helps support diluted sample 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 Ca-11 is well suited for reliable direct calcium ion testing.
