The M900 is the first major redesign for a GLA since 2005. The M900 is designed to be used in feedlots, dairies, universities and pharmaceutical studies. The M900 is smaller and lighter, while maintaining the durability that you expect from a GLA Thermometer, with an anodized aluminum box and sealed USB charger port. It features a LCD backlit display with battery life and charging icons on the main screen. With an extended battery life, you can even check the remaining battery % on your screen.
