The HYDROTIMER is a precision instrument calibrated to meet the ASTM International E 2380-05 Standard.

The HYDROTIMER is a self contained outflow meter.
It is a hands-off operation which produces consistently accurate results regardless of the operator as long as the tests are performed in accordance with instructions.

An outflow meter can be useful in proactive pavement evaluation, or investigating wet weather accident sites. This device measures the ability of the pavement to relieve water pressure from the face of vehicular tires, and thus indicates the degree of hydroplaning potential inherent to the pavement under wet conditions (skid resistance).
