We offer a range of dedicated instruments for measuring certain physical water properties. These are reliable, handheld, portable water resistant, electrode-based meters with a digital read out on a large, easy to read digital display for simplicity of use, for laboratory or field use. They can be used on a variety of qualities of water, from clean, transparent water to very contaminated or dirty water.

Meter Description Type Range
I-1000 pH Double Junction Meter pH -1.00 - 15.00 pH Units
I-1400 CTS Testr™ Conductivity
0.0 - 2,000 μS & 2.00-200.00 mS
0.0 - 1,000 ppm & 0.10 - 100.00 ppt
0.000 - 10.00 ppt

The CHEMetrics CTS Testr™, depicted left, is a 3-in-1 combination meter measuring Conductivity, Total Dissolved Solids (TDS) and Salinity. The pH Double Junction Meter is a dedicated pH testing meter.

Both meters provide direct readings of water samples and do not require test kits or reagents. Features include sample temperature display, optional temperature compensation, a hold mode when withdrawing the meter from the sample and a calibration mode. The CTS Testr™ also features a backlight. The meters require periodic calibration using calibration solutions, dependent on requirements. Each meter comes in a plastic storage case and includes an electrode and sensor cap, 4 AAA batteries and instructions. Both instruments are manufactured and guaranteed by Oakton Instruments, Inc.
