Sensors and Equipment
Except for ceilometers and lightning sensors, Mesotech does not design or manufacture sensors or interrelated equipment for use with weather systems. However, we do work with several reputable firms that supply high-quality, cost-effective sensors and parts for use in multiple applications. The following list includes the sensors and equipment we often recommend to our customers. The PDF document associated with each item includes additional information and technical specifications.
In addition to the sensors featured here, Mesotech can provide sensors that measure conductivity, dissolved oxygen, GPS, ice accretion, and soil heat flux. We can also provide additional equipment such as towers, data storage, enclosures, M & C peripherals, power supplies, solar panels, and sensor mounts.
You can always contact us if you have questions regarding any sensors or equipment.
