LDR-930 is a high accuracy meter used to measuring pH, Oxidation-Reduction Potential and ion concentration.

:: Ion concentration mode directly displays readings in ppm,ppt or any other units of your choice:: Calibrate up to 3 points for pH using USA or NIST buffer sets; Up to 5 points for ion concentration measurement:: Auto-buffer recognition eliminates calibration mistakes and ensures calibration accuracy:: Automatic temperature compensation for best accuracy under fluctuating temperatures:: Meter automatically calculate and display electrode slope:: Automatic message prompts help your easy to operate meter:: Expanded memory stores and recalls up to 99 data sets:: USB Communication interface can be sent data to PC
