Tamilnadu Engineering Instruments

Choolaimedu, Chennai, Tamil Nadu

our firm is engaged in offering a comprehensive range ofdigital moisture meter, which is deemed to be perfect for contractors and homeowners for the purpose of accurately measuring moisture content in wood, concrete, drywall, sub-flooring & other construction material. In order to satisfy the varying needs of our clients, we offer these meters with audible alarms with 8 different tone levels.

some of the key features of these meters are written below:

• strong stainless steel pins
• lcd moisture level indicator
• built-in low battery indication
• hold button to freeze/hold reading
• economically designed

Details :

• This test is done to assess the quality of concrete by ultrasonic pulse velocity method as per IS: 13311 (Part 1) – 1992. The underlying principle of this test is –
• The method consists of measuring the time of travel of an ultrasonic pulse passing through the concrete being tested. Comparatively higher velocity is obtained when concrete quality is good in terms of density, uniformity, homogeneity etc.
