The HORIBA LAQUA 200 Series is a range of rugged handheld water quality meters covering pH, ORP, dissolved oxygen, conductivity, resistivity, salinity, TDS and temperature. Pick the parameter set you actually need and you get a purpose-built instrument rather than paying for channels you will never use.
Every model logs data internally, calibrates against recognized standards, and is built for both benchtop and field work. Meters are available on their own, or as complete kits that arrive ready to measure with electrodes, calibration solutions and a hard carrying case included.
Which parameter set do you need
-
PH — pH, ORP and temperature
-
EC — conductivity, salinity, resistivity, TDS and temperature
-
DO — dissolved oxygen and temperature
-
PC — pH, ORP, conductivity, salinity, resistivity, TDS and temperature
-
PD — pH, ORP, dissolved oxygen and temperature
210 or 220
-
210 models store 500 data points. The right choice for spot checks and routine QC.
-
220 models store 1000 data points and add an RS-232 interface for direct output to a PC or printer. Choose these where records must be exported rather than transcribed.
Meter only or complete kit
Meter only supplies the instrument without electrodes, solutions or case — sensible if you already hold compatible electrodes or intend to specify your own.
Complete kit adds everything needed to start measuring:
-
pH kits — 9652-10D gel pH electrode with epoxy body and 1 m cable, pH 4.01 / 7.00 / 10.01 calibration solutions (60 mL), carrying case
-
EC kits — 9383-10D conductivity electrode, epoxy body, cell constant K = 1 cm⁻¹, 1 m cable, conductivity standards at 84 µS/cm, 1413 µS/cm, 12.88 mS/cm and 111.8 mS/cm (60 mL), carrying case
-
DO kits — 9552-20D galvanic membrane dissolved oxygen electrode with 2 m cable, carrying case
-
PC kits — both the pH and conductivity electrodes above, pH 4.01 and 7.00 plus EC 1413 µS/cm and 12.88 mS/cm standards, carrying case
-
PD kits — pH electrode and DO electrode, pH 4.01 / 7.00 / 10.01 standards, carrying case
Applications
