The Reed DT-1236L portable contact/noncontact tachometer measures
up to 99,999rpm, has a laser beam for noncontact measurements and
an LCD screen. This contact/noncontact portable tachometer is
used for measuring the speed of motors, conveyor belts, and other
moving and rotational systems. It measures rotational speed from
10 to 99,999rpm for noncontact measurements, and from 0.5 to
19,999rpm for contact measurements, with + or - 0.05% accuracy.
It measures surface speed from 0.5 to 1,999.9m/min. Its optical
sensor is a laser beam that works at a distance from 50 to
2,000mm for user safety. The LCD screen presents test results and
the unit of measurement, and it can store maximum, minimum, and
last test result values for ease of data recall. The CE mark
indicates compliance with applicable EU directives. It comes with
two cone contact adapters, one funnel contact adapter, a surface
speed wheel, reflective tape, batteries, and a hard-sided
carrying case. This tachometer is suitable for measuring
rotational speed and other measurements in mechanical or
industrial engineering environments.

is depth, the horizontal distance from front to back.
Tachometers measure the rate of rotation or surface speed of
motors, conveyor belts, and other moving systems. Contact
tachometers take measurements through direct contact with the
moving surface, and can measure both rpm and surface speed.
Typically, contact tachometers come with a range of attachments
that can be used to measure speed on different kinds of rotary
systems, which may include tips used for measuring shafts with a
central hole or flat end surfaces, and rotary wheels for
measuring conveyor belts. Noncontact tachometers take
measurements from a distance using a beam of infrared light, and
provide highly accurate measurements. Contact tachometers are an
excellent choice for dirty and dusty environments; noncontact
tachometers only calculate rpm but are considered safer because
they do not require the operator to be in close contact with the
moving surface. Contact/noncontact tachometers, also known as
dual, or combination tachometers, can be used to take contact and
noncontact measurements. Some tachometers can also take other
types of measurements, such as count or frequency, while others
can output data to a computer for analysis. Tachometers are used
in applications such as automobile maintenance, mechanical
engineering, and maintenance of industrial equipment.
Reed Instruments manufactures test and measurement equipment such
as pressure gauges, electrical testers, temperature and humidity
instrumentation, and inspection instruments. The company, founded
in 2004, is headquartered in Wilmington, NC.
