Mitutoyo AOS Absolute Digimatic Caliper line with exclusive AOS Sensor Technology. This patented Advanced Onsite Sensor (AOS) offers improved measurement dependability by increasing resistance to harsh workshop conditions. The new electromagnetic inductive sensor repels dirt, oil and water that can cause false readings. The Absolute (ABS) sensor eliminates the necessity of setting the reference when the tool is powered. An ergonomic slider design and increased battery life (3.5 years under normal operations) rounds out the new features of this line.
