Free Chlorine Tester for Pool - The Digital Chlorine Tester can quickly help you monitor the concentration of free chlorine ions in your swimming pool. For most pools, the free chlorine concentration range is usually between 1-3 ppm. This effectively purifies the water while keeping it clear and transparent, making the pool look more appealing and swimmers to enjoy a healthy and pleasant swimming experience. Salt Tester for Saltwater Pool - Salinity meter can help check the salt level (Perfect level: 2700-3400 ppm) of the saltwater pool and hot tub with salt chlorinator system. Help the salt chlorinator work more efficiently in the appropriate salinity value.The Salt meter can help you keep your pool clean and avoid the negative effects of too much or too little salt on your body and pool equipment. pH Level Tester for Pool- pH: 0.00~14.00; ph pool tester can help check the pH level of pool. Maintaining the proper pH level is critical to the operation and maintenance of saltwater pools. Typically, the Perfect pH range is between 7.2 and 7.8. Regular pH testing and adjustment can help clean water, comfortable swimming, and protect pool equipment from damage. Pool Chlorine Tester VS Pool Test Strips - When testing with test strips, you have to the value of your pool based on the color of the strips; however, free chlorine meter are simpler, more accurate, and friendlier to color-insensitive users than test strips. Simply place it in the water for a few seconds to get an accurate reading. Easy to Use - The 7-in-1 ORP Meter accurately measures FAC, pH, SALT, EC, TDS, ORP and TEMP values. Backlit design allows measurements in dimly lit environments. Pocket size design to help you measure inground pool, spa, thermal pool and anytime, anywhere. Have you been struggling to find a saltwater pool tester that is bothaccurate and easy to use? Yieryi multifunctional pH EC meter will tell you the answer. Note: The pH of the swimming pool water should be between 6.5-8pH, and the ORP should be between 487-840mv so that the FAC (chlorine) value can be displayed normally. If any value of PH and ORP is not within this range, FAC will not be displayed normally.
