Flexible Laboratory bench multi Meter makes your testing of critical water quality parameters more efficient
Two input channels for simultaneous measurement of pH, Conductivity, Total Dissolved Solid (TDS), Optical Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Oxydo Reduction Potential (ORP/RedOx), Temperature, Ion-Selective Electrode (ISE) direct concentration reading for Ammonia, Ammonium, Fluoride, Chloride, Sodium - connect any Intellical™ smart probe.
The intuitive user interface for simple operation, reliable and accurate results
Guided calibration and check standard routines reduce calibration errors while stabilization alerts and visual measurement locks ensure that you can trust the accuracy of the results.
Trust your measurements - Intellical smart probes store all calibrations in the probe
Calibration history allows quick and easy change out of probes without re-calibrating. The HQD™ smart system records serial numbers, current calibration data, user ID, sample ID, time, and date automatically in the data log for complete Good Laboratory Practice (GLP) traceability.
Enhance data connectivity with easy to read results
Internal USB ports simplify data transfer, peripherals, and software updates and connection to PCs printer and keyboards, with a large ultra-bright backlit LCD screen with a large font size for convenient reading.
Improve productivity and save laboratory space
Multimeter capabilities in one instrument with Intellical probes make switching parameters fast and easy by automatically recalling your measurement settings.
