Versatile, compact meter works in a field or laboratory setting?includes buffer for convenience and savings.|Handheld meter provides 0.01 pH accuracy and dual-line display for simultaneous pH and temperature readout Replaceable, double-junction electrode sensors save time and money IP67-rated (waterproof) housing sits flat on the table and floats in water|Bundled for convenience and to save you money!|The Oakton? pHTestr? 30 is great for outdoor applications?take pH measurements in lakes and streams. Designed to be waterproof and float in water, you can even attach a line to the housing for easy retrieval. The replaceable sensor ensures easy maintenance, and the double-junction electrode handles wastewater, sulfides, heavy metals, and TRIS. The glass pH bulb is recessed 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 auto-buffer recognition. Additional features include automatic temperature compensation (ATC), hold function, auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator. The most common pH calibration buffers are also included! Maintain accuracy throughout the meter's range. ? All Oakton pH buffers are traceable to NIST standard reference materials ? Buffer solution lets you calibrate any pH instrument to ensure accuracy ? Makes calibration easy - simply adjust your instrument to the pH value of the solution ? If unopened, shelf life is 2 years; once opened, use pH 4 and pH 7 within 90 days, pH 10 within 30 days ? Store buffers away from direct sunlight. ? Buffer solutions are color coded for quick visual reference: pH 4.01 buffer in red pH 7.00 buffer in yellow pH 10.01 buffer in blue
