Listed below are the solutions offered by Fresh Produce Instruments for professional water quality measurements:

COM100 EC-TDS-Temperature Combination Tester

This waterproof (submersible) tester measures electrical conductivity (EC), total dissolved solids (TDS) and temperature in water quality testing, water purification, wastewater regulation, labs & scientific testing, pools & spas, aquaculture, hydroponics, and more. Three different digital calibrations options (KCl, 442TM, NaCl) allow professionals to choose with the ability to recalibrate in the field and includes a cap, batteries, and lanyard. The large, easy-to-read display shows simultaneous temperature readings for quick and accurate measurements.

LAQUAtwin EC-22 Meter

The only pocket meter that directly measures conductivity in 0.12ml sample! There is no need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the sensor. This procedure saves professionals time and prevents wasting precious samples. The LAQUAtwin EC-22 meter is supplied with 1413µS/cm & 12.88mS/cm conductivity standards (14 ml each), conditioning solution (4ml), 2 x CR2032 batteries, dropper, and instruction manuals.

LAQUAtwin pH-22 Meter

The unique sensor of the LAQUAtwin pH-22 allows pH measurement of viscous liquids, solids, and even powder samples in a minimum sample of 0.1ml (or 0.05ml sample with sampling sheet B). This meter can be easily calibrated by placing a few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample. Purchase includes pH 4.01 & 7.00 buffers (14 ml each), 2 x CR2032 batteries, dropper, instruction, and quick manuals.

PH200 Waterproof pH & Temperature Meter

The PH-200 waterproof tester provides all the features you need for commercial or household use. It works great for measuring pH (Range 0-14) and Temperature (Range: 0°C - 80°C) in water purification applications, wastewater regulation, aquaculture, hydroponics, labs & scientific testing, pools & spas, ecology testing, wine, coffee, agriculture and much more. Waterproof (submersible) housing also floats for added convenience. Purchase of this device includes a cap, batteries, lanyard, and pH 7.0 buffer solution.
