Oakton pHTestr 30+ Waterproof Pocket Tester

Versatile, compact design works in a field or laboratory setting

• pH accuracy along with dual pH and selectable C or F temperature display
• A complete meter with key features at an economical price
• Replaceable, double-junction electrode sensors save time and money
• IP67-rated housing sits flat on the table and floats in water
Waterproof pHTestr 30 is great for outdoor applications such as taking pH measurements in lakes and streams. Designed to float in water, you can even attach a line to the housing for easy retrieval. Valox sensor housing resists most chemicals. The pHTestr 30 has a replaceable sensor for easy maintenance. pHTestr 30 purchased before Oct. 2019 use replacement sensor 35624-38. pHTestr 30 purchased after Oct. 2019 use replacemenr sensor 35634-03. Double-junction electrode sensor handles wastewater and solutions containing sulfides, heavy metals, and TRIS. Electrode sensor offers a clog-resistant Kynar® junction and a recessed, glass pH bulb to protect against breakage. The keypad clicks to confirm operation, and allows access to a variety of functions. Calibrate up to three pH points with the auto-buffer recognition at both USA and NIST standard buffers. Additional features include a automatic temperature compensation (ATC), hold function, auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator.




Oakton Benchtop CON 700 Conductivity Meters

An affordable way to take consistent, accurate conductivity measurements in your laboratory!

• Compact size frees up bench space
• Large brightly lit display allows for easy reading of measured values
• Easily toggle between conductivity and TDS at the touch of a button!
CON 700 meter reads 0 to 200 mS across five ranges—autoranging feature automatically gives the best resolution for your measurements. Calibrate at up to five conductivity points (one per range) for improved measurement accuracy. Adjustable temperature coefficient provides additional accuracy. Cell constant is selectable for very high or low range measurements - meter is flexible to your application. Selectable manual or automatic temperature compensation gives greater precision. Meter is encased in a compact 6-1/8" L x 6-7/8" W x 2-3/4" (15.5 x 17.5 x 6.9 cm) housing which takes up a minimum of bench space-nearly 40% less space than comparable meters. Water-resistant membrane keypad and convenient pullout reference guide provide useful features for the lab. Oversized display measures 3-1⁄4" x 2-7⁄16" (8.3 x 6.2 cm) and is brightly lit for easy viewing of measurements. Display shows conductivity or TDS and temperature and has a “ready” indicator and Hold function. Additional meters features include datalogging capabilities up to 100 points, a built-in electrode stand that is switchable to either side of the meter, and selectable °F/°C temperature measurement.



Oakton CON 6+ Handheld Conductivity Meters

Autoranging conductivity with temperature measurement

• CON 6+ meters have five auto-ranging measurement modes — up to 200.0 mS (200.0 ppt)
• Temperature readout in °C with the push of a button
• Rubber boot with built-in stand protects meter and adds functionality
These microprocessor-based meters feature easy, push-button operation that offers high accuracy at an extremely affordable price. A quick and easy single-point calibration covers all five ranges with the CON 6+ meters; for greater precision, single points can be calibrated within each of the five measurement ranges. Additional features include a convenient Hold function and auto-off function that shuts meter off after 20 minutes of nonuse. Programming functions allow customization of meter for temperature compensation, temperature coefficient, normalization, and cell constant for better accuracy in varying applications.
