<p>Chlorine pH Cl2 Tester</p><p> The basic tool for quickly and accurately measuring pH and chlorine. It is the most commonly used water disinfectant to kill bacteria, algae, and microorganisms.</p><p> The ideal tool for keeping pools or spas within a safe pH and chlorine range, without any chemicals or guesswork.</p><p> An electrical tester for pH and chlorine (Cl2) levels for routine monitoring of pH and chlorine levels in pools, spas, and various water sources.</p><p> When chlorine and pH leak out, it can cause diarrhea and ear and skin infections. Good chlorine and pH keep bad bacteria at bay: if the pH is too high, the electricity killed by chlorine will be used up. When large amounts of nitrogen (feces, urine, sunscreen, or sweat) or other organic substances enter the pool, chlorine is also consumed. That's why it's always best to test both chlorine and pH—it can change daily depending on pool usage. Keeping your pH in the proper range is important for maintaining the surface treatment of equipment and pools. Your chlorine will dissolve more quickly at a low pH. A high pH value will invalidate chlorine gas. </p><p> This electrical measuring instrument can save you time and money. </p><p> Note: Except for pool or spa water, the detector will not immerse the recommended values in the water. </p><p> Technical Data Sheet </p><p> The recommended chlorine content for swimming pools and spas is 1.2 to 1.7 ppm </p><p> The recommended pH for swimming pools and spas is 7.2 to 7.8 </p><p> Size </p><p> Main unit: 180 mm x 20 mm </p><p> Handle probe: 150 mm long </p><p> Probe (limited to): 48 mm long </p><p> Cable (only): 300 mm long </p><p> Power supply: 1 AA alkaline battery (1.5 V) </p><p> Bare metal weight: 193 g (without battery) </p><p> Gross weight: 260 g </p><p> Including packaging size 200 * 150 * 70 MM </p><p> Delivery quantity: </p><p> 1 pH and Cl2 probe tester </p><p> 1 manual </p><p> 1 sheet of sandpaper </p><p>
