This product is non-toxic, non corrosive, please keep it after storage, placed in the child can not touch the place.
It is widely used in tap water, surface water, soft water, boiler water, water for heating and ventilating equipment.

Hardness developer

【Usage method】：25ml measured water, add 5 drops, the color is red (not normal color), such as blue (normal color), hardness is below 3ppm (as measured in water to add 1 drops, the color is blue, hardness is less than 1ppm).

Hardness titrant A

【Usage method】： to the small cylinder drop, 1 drops shake for 3 seconds, until the cylinder color changed from red to blue, write down the number of drops, the total hardness of PPM * 10= the number of drops of water

Hardness titrant B

【Usage method】：to the small cylinder drop, 1 drops shake for 3 seconds, until the cylinder color changed from red to blue, write down the number of drops, the total hardness of PPM * 50= the number of drops of water

Remarks: 1mmol/ liters =2 mg equivalent / liter =100ppm can be detected 60 times.

【Storage period】：preservation at room temperature.
