GLA thermometers are used worldwide in feedlots, cow/calf operations, dairies, universities, pharmaceutical studies, zoos, and veterinary offices for large and small animals.

We have been a family-owned business for three generations. By focusing on manufacturing one product, GLA insures that its animal thermometers are the best available. We pride ourselves on producing a high-quality product, providing outstanding customer service and offering dedicated product support to all versions of our thermometers, regardless of age.

Every GLA thermometer is hand built in small batches using components from small American vendors. Our vendors range from a local engineer, to wire company in Wyoming, a cable company in Massachusetts, an assembly house in Minnesota and a local machine shop. (For a list of the vendors we proudly use, please see “Vendors” on the “About” page.)

GLA team members are always available to answer questions, regardless of when or where a GLA thermometer was purchased. GLA will answer your telephone call, reply to your emails and most often that answer will be provided by someone who has helped to manufacture your product in one production process or another.
