- Hardened stainless steel construction for protection of caliper and ABSOLUTE linear encoder technology components.
- Four-way measurement capability for multiple applications: outside diameter (OD), inside diameter (ID), depth, and step.
- Digital, single-value readout LCD display in inch and metric units for readability.
- Function control buttons on caliper face for ease of access: Origin, On/Off, and Zero/ABS (Absolute Scale).
- IP67-certified for protection against dust and temporary submersion in water.
The Mitutoyo 500 series ABSOLUTE Coolant Proof Caliper is a dust
and water resistant digital caliper made of durable hardened
stainless steel using Mitutoyo’s ABSOLUTE linear encoder
technology. This caliper conforms to IP67 protection levels
enabling it to operate in workshop conditions exposed to water,
dust, coolant, or oils.
Although identical to dial and vernier calipers in its ability to
make precise measurements, the digital caliper has an LCD that
displays in inch and metric units which increases reading
reliability, and reflects all ABSOLUTE system activities. This
digital caliper has accessible function control buttons, such as
Origin to set and retain the original measuring point, On/Off to
automatically shut off the caliper after 30 minutes, and Zero/ABS
(Absolute Scale) to zero-set the LCD display. The Absolute Scale
(ABS) function tracks the set origin point, even after shutoff.
Once on again, the caliper can immediately start measuring,
without zero resetting. The LCD can be "zeroed out" before making
and comparing incremental measurements without having to subtract
the first measurement from the second.
The 500 series ABSOLUTE Coolant Proof Caliper has the ABSOLUTE
electromagnetic induction linear encoder to help prevent
overspeed errors. It measures outer diameter (OD), inner diameter
(ID), depth, and step, where the butt end of the fixed jaw
measures one end of a work piece before its upper/lower or
inner/outer "steps" are measured. LCD resolution is .0005"
(0.01mm), and repeatability is .0005" (0.01mm). Dust/water
protection level is Ingress Protection 67 (IP67)-certified, which
means that the electronic components are resistant to debris and
to submersion in liquid under standard conditions for up to 30
minutes. An alarm alerts the user to low voltage and counting
value composition errors. A rolling thumbwheel makes fine
adjustments and a thumbscrew locks the scale’s position. Response
speed is unlimited. Each caliper includes, and is powered by, one
SR44 silver oxide cell battery that lasts approximately 3 years
with normal use.
Calipers measure the distance between two sing sides of an
object. They make inside, outside, depth, or step measurements,
according to their type. Calipers are commonly used in
architecture, metalworking, mechanical engineering, and
machining. The simplest calipers have two legs to mark the two
points and require a ruler to take the measurement. More complex
calipers use two sets of jaws instead of legs and have up to two
graduated scales. Vernier, dial, and digital calipers give direct
and accurate readings and are functionally identical, having a
calibrated scale with a fixed jaw, and another jaw with a movable
pointer that slides along the scale. The vernier caliper has a
scale sliding parallel to the main scale for an additional,
fractional reading to improve measurement precision. The dial
caliper has a circular dial with a pointer on a toothed gear rack
replacing the second vernier scale. As with the vernier, this
second measurement is added to the reading from the main scale to
obtain the result. The digital caliper takes a differential by
zeroing the display at any point along the slide, with an LCD
that displays a single value in English and/or metric units.

equipment, and systems. The company was founded in Tokyo in 1934
and formed Mitutoyo America Corporation in 1963, which is
