Ca++ tester LAQUAtwin Ca-11

temperaturecalibrationfor water quality

HORIBA's unique compact meter integrates the electrode, display and sample container to enable simple, effective on-site testing by direct measurement from a single drop. The only pocket meter that directly measures calcium ion concentration in 0.3ml sample (or 0.05ml sample with sampling sheet B). Unique sensor allows measurement of viscous liquids, solids, and even powder samples. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample. Minimum sample volume: 0.3ml (0.05ml with sampling sheet B) Up to 2 calibration points Auto standard recognition: 150 & 2000ppm calcium (default) Changeable high and low calibration values Multiplication compensation: 0.01 to 9.90 Temperature and mV display Temperature calibration: 5 to 40.0 ºC Auto hold / auto stable measurement Auto power off: 30 mins. Low battery indicator IP67 Rating dust & waterproof Replaceable sensor 400 Hours battery life: continuous use without backlight Material: ABS epoxy Display: custom (monochrome) digital LCD with backlight Operating conditions: 5 to 40 ºC, 85% or less relative humidity Warranty: 2 years - meter, 6 months - sensor Packed in handy carrying case Supplied with 150 & 2000ppm calcium standards, 5 x sampling sheets B, 2 x CR2032 batteries, dropper, instruction and quick manuals Measurement Principle - Ion Selective Electrode Minimum Sample Volume - 0.3ml (0.05ml with sampling sheet B) Measurement Range - 4 to 9900 ppm (mg/L) 0.1 to 250 mmol/L Resolution - 0 to 99 ppm: 1 ppm 100 to 990 ppm: 10 ppm
