Product description

Description:

When chlorine and pH are from whack, it can cause diarrhea and infection of the ear and skin. A good chlorine and pH keep bad bacteria in the bay: if the pH is too high, the electricity killed by chlorine will be exhausted. When a large amount of nitrogen (excreta, urine, sunscreen or sweat) or other organic matter enters the pool, chlorine is also eaten. That's why testing chlorine and pH is the all the time - she can change every day depending on the use of the pool. Keeping your pH within the proper range is important to keep the surface of the equipment and swimming pools. Your chlorine will dissolve faster at low pH. A high ph value will invalidate the chlorine."br""br"Specification:"br""br"Condition:100% "br""br"Material: Plastic"br""br"Color: As shown in the picture"br""br"Main Unit: Approx.190X20mm / 7.5X0.8in"br""br"Handle Probe: Approx.150mm / 5.9in(L)"br""br"Probe (only): Approx.48mm / 1.9in(L)"br""br"Cable (only): Approx.300mm / 11.8in(L)"br""br"Battery:1X 1.5V AA battery(Not included)Recommended chlorine content for swimming pools and spas from 1.2 to 1.7 ppm"br""br"Recommended pH for pools and spas is 7.2 to 7.8"br""br"Package List:"br""br"1X PH/CL Meter"br""br"1X Manual"br""br"1X Sandpaper"br""br"Note:"br""br"The detector will not recommend immersion, except for pool or spa water.
