Hydrometric Rod

Hydrometric rod made of anodized aluminum with anti-corrosion treatment to resist even in environments with contaminants and abrasions. The colouring with high iridescent effect for an excellent visibility of scale from far, and in any application (cement, bricks, soil, etc.). The choice of colours is the result of careful consideration and numerous tests carried out in the field and on the applications already developed, where is essential to ensure to the observer the best possible visibility even in unfavourable conditions during flood events . The hydrometric rod is made in modules of 1 meter with indication of measurement every ten centimeters and reference notches every centimeter, for the indication meter by meter, the rod may be furnished by a plate showing the desired value in meters.

SS-P1 Hinged Arm

Arm support for radar and ultrasonic sensor for bridges or walls, length 1500mm (square tube 40x40mm 3mm) completely folding at 90° to facilitate maintenance of the sensor. 630x130x8mm base plate with 6 holes for dowels. Is possible to lock the hinge with padlock. Screws in stainless steel.
