This instrument gives a presumably accurate result almost immediately. Supplied calibrating solutions are sparse but can evidently be reused if the probe is carefully cleaned as directed. A single multi-function button that works well replaces the two or three often present on other models. Allegedly waterproof, and the probe is replaceable. Sealing probe cap holds supplied soaking solution to protect and prolong life of electrode. Extra batteries supplied are a plus. Good instructions and warranty. Factory calibrated and even has its own serial number. Not a professional device that can cost hundreds, but certainly worth its price.
