<p>[5-in-1 pH METER] - Meter has a five-in-one function, which can measure PH, TDS, EC (Electrical Conductivity), Salinity %, Salinity ppm, and Temperature - with high precision every time. All-round measurement of water quality to consistent results.</p> <p>[Accurate pH Tester] - Featuring a solid probe, you can get a full measurement range of 0-14pH, 0.01 pH resolution. The pH meter uses a 3-point calibration for maximum accuracy, and includes extra calibration powder.</p> <p>[TDS Measurement] - Fast and accurate TDS \/ PPM testing for hydroponics or anywhere TDS is critical. The TDS Range is 0~10,000ppm. Accuracy is 2%.</p> <p>[EC Measurement] - Measure Electrical Conductivity of either fresh or salt water.</p> <p>[Saline % and Saline ppm Measurement] - Conveniently and easily keep track of saline levels by either percentage or ppm. Great for aquarium, saltwater pools, saltwater spas or anywhere salt levels are critical.</p> <p>[Temperature Compensation] - The pH meter auto-calibrates to the sample liquid temperature, which guarantees accuracy regardless of temperature.</p> <p>Colour:Black</p> <p>Material:ABS</p> <p>Package Contents:</p> <p>1 x 5-in-1 Water Meter</p> <p>1 x USB charging cable</p> <p>1 x English manual</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
