Measure and record pH values in the lab or field using the PH-1 accessory. The supplied app provides real time display of pH, millivolts, ambient temperature and solution temperature. When used with a GPS enabled device, the pH Meter application will record where and when your measurements were taken. Results can be grouped by location or date, and emailed to a central records office. Using the pH Meter app eliminates the chances or transcription errors, and improves efficiency. Ideal for the classroom – the pH Meter application makes it fun to measure and record pH values. It is an excellent tool for teaching the chemistry of acids/bases, and introductory electrochemistry. Students can install the app on their own iPod or iPhone, and share a single sensor for experiments. Suitable for any process where pH measurements are routinely performed. By recording the pH value with a time stamp and location, this app eliminates any chance of mistakes when recording readings. Works with location aware devices to log the coordinates where readings were taken for analysis and auditing purposes. Analog to Digital for pH/mV: 13bit; for Temperature: 10bit. BNC pH sensor connection. 2.5mm plug temperature connection. 30K NTC temperature sensor.

This paper is used for the determination of fluoride ions and gaseous hydrogen fluoride (H2 F2 ). The pinkish-red paper turns yellowish-white in the presence of fluorides. Substantial amounts of chlorates, bromates and sulphates cause white discolorations of the paper. These interferences are readily circumvented. Limit of sensitivity: 20 mg/l fluoride

Manufacturer: Sper Scientific Brand: Sper Scientific Model: 850051

Easy to carry, simple to operate and sufficient for most field pH tests. Highly stable and accurate readings with a large LCD display. Designed for simple one-hand operation. Automatically calibrates to pH 4, 7, 10 buffers and can be adjusted to recognize non-standard buffers as well. Features hold function, and auto power off with low battery indicator. The case is IP65 waterproof, and will float if accidentally dropped into the water. Comes with 4 button-cell batteries and a built-in electrode kept moist with a protective cap. Dimensions: 6½" × 1½" × 1½" (165 × 38 × 38 mm) Weight: 2.3 oz (65 g) .
