Bridges
-
Equip your testing environment with portable, precise Wheatstone bridges and Kelvin double bridges from Transcat. The Wheatstone bridge is a device containing a divided bridge circuit for taking highly accurate resistance measurements. It captures the value of an unknown resistance, in comparison to known resistors within the circuit. Precision bridges provide exact resistance measurements in the miliohms (m_) to megohms (Mohm) range within their specified accuracies. We offer portable Kelvin double bridges, which are forms of the Wheatstone, designed to measure low resistance – with high accuracy. Transcat also stocks individual resistors, which provide resistance standards in low to high values. They operate in conjunction with potentiometers or bridges.

Bridge Decking Testing Equipment
-
The testing process can detect blow holes, inclusions or thin areas in 'sprayed-type' membranes. Because the concrete contains a small amount of water, it is electrically conductive and a DC Pinhole Detector can be used to create a high voltage which is passed over the surface by the use of a brush electrode. An alarm will sound to identify any small defects which can be rectified so that the integrity of the coating can be verified.
