Multiparameter Meters
HANNA INSTRUMENTS INC Low Range pH/Conductivity/TDS Tester
The low range Combo pH, EC, TDS (ppm) and temperature meter is one of Hanna's most popular meters. The waterproof design, simple operation, and replaceable electrode mean that you can rely on this meter for years.The HI98129 is designed for low range use (0 to 3999 µS/cm or 0-2000 ppm). Choose the HI98130 for the high range model.Compact & waterproof design fits right in your pocket so you can take it anywhere.Replaceable pH electrode extends the life of your tester for years.
Cole-Parmer Oakton PC700 PC 700 Benchtop Meter with Electrode Stand
The PC700 meter offers a new compact design that is over 40% smaller than other benchtop meters. The large display is easy to read even at a distance. Dual-display allows you to read both a measured parameter and temperature at a glance. The meter features pH auto-buffer recognition for both USA and NIST buffer sets (1.68, 4.01, 7.00, 10.01 and 12.45 or 1.68, 4.01. 6.18. 9.86, and 12.45), automatic or manual temperature compensation, temperature in °C, display Hold, and water-resistant membrane keypad. Previous calibration points, electrode slope and offset, and conductivity/TDS cell constants (0.1, 1.0 and 10) are stored in memory for quick and easy retrieval. The convenient pull-out quick reference card keeps keypad functions at your fingertips.
Cole-Parmer Oakton pH 700 Benchtop Meter with Probes and Stand
Compact footprint is over 40% smaller than other benchtop meters. Large display permits easier readout viewing. Datalogging allows you to store and recall up to 100 data sets. The easy-to-use, microprocessor-based pH 700 benchtop meter measures pH, mV, relative mV, and temperature. The large, dual-display LCD provides excellent visibility-even from a distance. Automatic temperature compensation (ATC) maintains reading accuracy even with fluctuating temperatures. Five-point pH calibration, with automatic buffer recognition for both USA (pH 1.68, 4.01, 7.00, 10.01, 12.45) and NIST (pH 1.68, 4.01, 6.86, 9.18, 12.45) pH buffers, makes for easy calibration no matter which requirement you need to meet. Meter features HOLD, ATC, selectable f or C measurement, recall of electrode slop and offset, and electrode diagnostics. The convenient pull-out quick reference card keeps procedures handy at all times. Meter accepts any pH or ORP electrodes with a BNC connector.
Hach Company Hach MP-4 Portable Meter (HMP4) - Probeless conductivity, TDS, resistivity, and temperature meter
The MP-4 Portable Meter is a cableless, single-handed instrument for rapid testing of conductivity, resistivity, total dissolved solids (TDS), and temperature in clean water applications.
