WD-35419-12 pH 700 Benchtop Meter Only with Stand, 110/220 VAC, 50/60 Hz by Oakton

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, 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.

As always, our waterproof meters are IP67-rated for both dust and water intrusion. Even with no probes attached!

• 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

WD-35806-22 Flat Surface, Self Cleaning, Single-junction, Kynar-body ORP Electrode (Use with pH 100, 200, 800, and 1000 controllers) by Oakton

A. In-line submersible electrodes feature a probe guard to protect sensor from damage. They can be placed in a tee fitting for in-line use. CPVC body with 3/4" NPT thread on both ends withstands temperatures up to 80°C.

B. Submersible electrodes are permanently encapsulated in a 3-ft pipe - perfect for tank installation. ABS plastic body withstands temperatures up to 80°C.

C. Semi-domed bulb electrodes with solution ground have a unique surface design that protects electrode from particulates and increases flow across the junction to keep the bulb clean. Graphite body acts as a solution ground. Withstand temperatures up to 100°C.

D. Self-cleaning flat electrodes have an innovative flat surface that prevents solids buildup. CPVC body with 3/4" NPT thread on both ends withstands temperatures up to 80°C.

E. PTFE junction electrodes are excellent for simple wastewater applications. PTFE junction and polymer gel reference electrolyte resist clogging. CPVC body with 3/4" NPT thread on both ends withstands temperatures up to 80°C.

F. PTFE junction electrodes with solution ground are excellent for tough wastewater applications. Solution ground pin eliminates ground loop and electrical noise problems. PTFE junction and polymer gel reference electrolyte resist clogging. Ryton body with 3/4" NPT thread on both ends withstands temperatures up to 100°C.

• Include BNC connector
• Built-in Pt RTD sensor with stripped ends for temperature (ATC) element
• ORP electrodes feature Pt band sensor
• Use electrodes with solution ground with our pH 200, 800, or 1000 controllers in areas with high electrical noise

WD-35413-00 pH/Con 700 Benchtop Meter with pH Electrode, Conductivity/Temp Probe, and Electrode Stand, 110/220 VAC, 50/60 Hz by Oakton

Easily toggle between pH, mV, conductivity, TDS, and temperature measurements at the touch of a button

The pH/CON 700 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 selectable in either °F or °C, display HOLD, and water-resistant membrane keypad.

Previous calibration points, electrode slope and offset, and conductivity/TDS cell constants are stored in memory for quick and easy retrieval. The convenient pull-out quick reference card keeps keypad functions at your fingertips.

• Space-saving design takes up less room on the bench than other meters
• Large display lets you see your measurements from across the lab
• Conductivity and TDS autoranging chooses the best resolution for each measurement
