Benchtop Multi-parameter Water Quality Meter LD-LMPWM-A43
Benchtop Multi-parameter Water Quality Meter LD-LMPWM-A43 with large backlit LCD (125 × 100 mm) display, measures pH, ORP, ion concentration, conductivity, TDS, salinity, resistivity and dissolved oxygen. Equipment saves space of the benchtop by combining multiple parameters in one unit. With expanded memory, it stores and recalls up to 500 data sets. Calibration due reminder informs the operator to calibrate the meter regularly. Setup menu allows you to set the number of calibration points, stability criteria, temperature unit, date and time, auto-power off, etc. USB communication interface for data transfer and timed interval readings.
SKU Code: LD-LMPWM-A43
