Secchi Water Clarity Tube
Designed to function like the traditional Secchi disk used in lake monitoring. A weighted Secchi disk is lowered into the tube by a line, allowing you to raise and lower the Secchi disk within the same water sample numerous times. This method allows for averaging the water clarity readings. At the top of the Secchi-Tube is a hole that drains excess water off to bring the water sample level down to the ”zero” mark on the centimetre scale. Made of polycarbonate with an easy-to-read centimetre tape. Features the Secure Stopper™ and all stainless steel hardware.
