Helps reduce overflow potential of light to medium amounts of suspended solids. 3、Casing: The float casing is made of safe ABS material, odorless, insulated, waterproof, and is IP68 rated. Rugged construction also makes this water level switch temperature resistant below 70 degrees. 4、Cable: The inner core of the cable is made of high purity copper wire, which effectively resists aging and impact, and has low resistance and low heat generation. 5、Application: It can be used in pools, oils, weak acids and alkaline water or oil tank environments, not suitable for where the control level difference is less than 40 cm.
