Wind / Solar Measurement System

3dot Energy provides meteorological mast at several heights up to 150 m on compliance with international standards like MEASNET, IEC etc. We can supply the mast and support clients to do installation and commissioning globally. Our staffs can install all kinds of mast. Our masts can be easily transported and installed in the short period of time and have unexpected quality at economical price. Our met mast will be fully galvanized to meet the extreme weather conditions. We can supply wind measurement system with pre-configured and ready for installation with below instruments.

Our masts are complying and customized to meet the design requirements of International standards like ANSI/TIA 222G, Indian Standard, and EIA/TIA 222G etc. The design has statistically calculated on pre fabrication. We have highly trained professionals who have installed up to 140m high mast and 70 more projects. Our staffs have capable of handling any critical environment. We have internationally recognized IRATA certified climbers for work at heights to ensure safety during installations at site.
