Benchtop Water hardness meter LBWM-A10
Benchtop Water hardness meter LBWM-A10 is equipped with large backlit LCD display, 2 to 
5 points calibration with low to high concentration range. The calibration due reminder 
alerts user for calibration of the meter on regular basis. The System menu allows setting the 
7 parameters like stability condition, auto-power off etc.  It measure salts of calcium & other 
elements at mg/L, mmol/ scale which causes hardness water.
