Met One Instruments History

In 1985, Met One Instruments, Inc. was formed to focus on the growing environmental market and the entire meteorological product line was spun off Met One, Inc. and incorporated as Met One Instruments, Inc., a private corporation.

The company has grown through careful planning, dedication to customer service and the ability to design and manufacture quality, user-friendly products to meet government standards worldwide as well as for communities aware of the importance of monitoring and sampling for the safety of their workers and citizens. For this reason, Met One Instruments’ engineers and developers always have the practical applications in mind when developing instruments with the most accurate information available. In today’s crowded field of air monitoring instruments, Met One Instruments is the standard for which all other instruments are measured.
