The HORIBA LAQUA 1500 and 2000 Series are benchtop water quality meters for laboratory and QC work, covering pH, ORP, conductivity, salinity, resistivity, TDS, dissolved oxygen, ion concentration and temperature. Every model ships with an integrated electrode stand and power supply, so the instrument arrives ready to set up on the bench.
Choose a meter-only version if you already have suitable electrodes, or a complete kit (-S) if you want a working setup out of the box — the kits bundle the matching electrodes and calibration solutions, so there is nothing further to specify or order.
1500 vs 2000 Series
-
1500 Series — the practical choice for routine testing, teaching labs and general QC. Kits are supplied with epoxy-bodied electrodes, which are more forgiving of knocks than glass.
-
2000 Series — adds capability and a wider model range, including dedicated dissolved oxygen and ion-selective instruments. Kits use the 9615S-10D refillable electrode with a chemical-resistant glass body, better suited to aggressive samples and higher-accuracy work.
