pH Paper Strips, pH 0 to 14

These EMD Science ColorpHast strips are designed for easy colorimetric indication of pH. The strips can be immersed in the sample for a long period of time, so weakly buffered solutions can be tested with accuracy. Just dip the strip in your solution and match the exact color of the pH on the strip to that of the box-it's that easy. There is no bleeding of dye, even in strongly alkaline solutions. pH paper strip show a distinct color change for each full pH unit change from pH 0 to 14.

Martini Instruments pH Meter, pH -2 to 16

The included electrode has a built-in temperature sensor and amplifier to prevent electrical interference. The large display shows readings in an extended range from -2 to 16 pH and simultaneously shows temperature from -5 to 105 °C or 23 to 221 °F. The MI105 has a stability indicator and hold feature that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. The battery life of the pH meter guarantees over 500 hours of continuous use. When switched ON it performs a self-check and displays the percentage of the remaining battery level to assure proper working condition. Calibration is performed automatically at 1 or 2 points using standard or NIST buffers.

Hach Pocket Pro+ pH Meter, pH 0 to 14

The Hach Pocket Pro+ is engineered to deliver accurate results. Backed up with built in performance diagnostics, you never have to guess when to clean or calibrate the sensor. You also get replaceable batteries for convenient field use, and a large, easy-to-read LCD screen. Includes: tester, 4 AAA batteries, lanyard, calibration solution and quick start guide.

Buffer Solution Kit

This "Singles" Buffer Solution Pouches Assortment Pack includes 5 pouches of each solution: pH 4.01, 7.00, 10.00 and deionized Rinse Water. pH "Singles" pouches are convenient, air-tight pouches with high-precision calibration standards. Ideal for field use-take them to your test site for on-the-spot calibration. Pouches are labeled with a pH vs. Temperature chart and CAS numbers for "Right-to-Know" requirements.

Oakton pHTestr 30 This is a handheld portable device used to take pH measurements in the laboratory and in the field. Included in Package: Meter, Electrode, four (4) 1.5 V batteries and Instruction Manual.

Hach Replacement Sensor

This replacement sensor is used for the Pocket Pro+ pH Tester.

Ohaus pH Pen Meter, 0.1 pH Resolution

Pen meters offer a convenient way to measure pH, or the relative acidity or alkalinity of a sample at a given temperature. The pH pen meters can be completely operated with just one hand, freeing up your other hand to handle sample. Pen meters are the economical option when you are simply looking for meters that will provide accurate measurement without restriction.

Oakton pH Electrode, pH 0 to 12

This Oakton pH electrode with BNC connection is ideal for field, clean water, and general purpose applications.

Storage Solution, 230 mL

This solution is used to hydrate the junction of pH or ORP electrodes when not in use. This extends the life of the electrode and ensures accurate calibration. When storing the electrode, insert the electrode into a beaker or test tube filled with this storage solution, just enough to cover the junction of the electrode.
