This is a very reliable and efficient instrument for determining water turbidity. Be very careful which model you buy. One for fresh water and the other for sea or salt water. The device is not marked anywhere on the body or device. Only the instruction and salinity range are given. Any seller cannot tell the difference and sell immediately. Know what you need and if you buy the right tool you will be very happy.
