Met One Instruments Inc. is one of the leaders in research, development
and manufacture of meteorological instruments, particulate monitors,
data loggers and environmental software. One of the oldest
instrument manufacturer's in the United States, MOI continues to
provide the leading edge in instrumentation, data logging, environmental
software and monitoring systems worldwide.
Projects have included entire meteorological monitoring networks
for countries from Asia to the Middle East, as well as the major
part of PM10 monitoring within the USA and International sites.
Onsite training and commissioning for complete end-user satisfaction
has always been the goal. Private industry, research institutions,
universities, military and home defense organizations, as well as
all levels of government environmental agencies are amongst its
The company began business in 1976 as Met One, Inc. The first of
several high quality "Met Set" meteorological monitoring systems
and a line of clean room monitoring instruments were introduced.
Growth was brisk and the company quickly outgrew the facilities.
In 1989 Met One Instruments, Inc. was formed to focus on
the growing environmental market and the entire meteorological product
line was transferred at that time.
The company has grown through careful planning, dedication to customer
service and the ability to design and manufacture quality products.
Additional growth has come about with company acquisition and joint
Northwest Technology was acquired in 1991; the company specialized
in fabrication operations for various semi-conductor and aircraft
companies. The facilities of Northwest Technology enabled MOI to
greatly expand instrumentation manufacturing. Beyond the fabrication
capabilities, Northwest Technology provided key knowledge of basic
robotics that was later employed in some of the air products.
Some landmark years for MET
1989 - Putting the MET back into Met One as the company commits
to quick response! This becomes a guideline for the future and the
market responds with the extra effort to insure the customer satisfaction.
1990 -The Multi-Met Meteorological System was introduced at the
annual Air Waste Management Convention. The Multi-Met added the
flexibility to join various weather sensors with customers' existing
SCADA systems and data loggers. Customers could easily upgrade existing
systems within budget.
1990 - Met Set 90 Weather Station was introduced as the first easy-to-use
data logger with each Met Set 90 configured by the factory for ease
of field installation. The company listens to its customers
and they respond.
1992 - Met One introduced the first of the LAB instrumentation
shelters for OEM and ambient monitoring. Again, company responed
to customer's requirements and successfully shipped hundreds of
shelters to various parts of the country and overseas. MOI
provided complete air quality systems with shelters as well as shelters
to other systems integrators.
1993 -' Plug and Play' sensors for the meteorological market are
invented and applied to the new AutoMet data logger. Customers no
longer needed to program their data logger; just plug the sensor
in, set the clock and be up and running. Estimated time of
deployment, with initial training, less than 5 minutes!
The meteorological product line of Teledyne Geotech was acquired
in and key personnel were moved into a new Dallas Regional office.
The acquisition provided Met One with increased sales base, seasoned
engineers and a new family of products. Existing TG product line
was expanded and improved over the next few years and has been a
significant contributor to the Met One product line.
1994 - Met One Instruments purchases technology to develop the
first US made continuous particulate monitor using beta technology.
Production begins in 1995 of the BAM 1020 and becomes the only USA
manufactured beta gauge with NRC license to ship within the USA.
Later, the BAM 1020 becomes the only USA manufactured
beta gauge to receive USEPA Equivalency.
1995 -The GT-640 Portable Particulate Monitor for emergency response
monitoring is introduced. With a solar/battery power option, the
unit quickly becomes a standard for fence line monitoring on construction
and earth moving sites.
Working with Mosel of Taiwan in 1995, they provided the company
with software products in three languages, English, Spanish and
1996 - The GT-321 Hand Held Particle Counter is introduced at the
American Industrial Hygiene Convention. The GT-321 becomes a volume
OEM product and is currently sold worldwide through dozens of organizations.
Sibata Scientific of Japan and Met One Instruments joined together
to share optical technologies during 1996 through 2000. This shared
effort helped in the development of several optical particulate-sensing
1997 - The GT-521 Hand Held Particle Counter is introduced with
expanded features including: data logging, two channel operation,
and user set points at 0.1 micron intervals. The GT-521 becomes
the most popular hand-held instrument.
1997 - MOI introduced Sonic Wind Sensing with the Model 50.5 Sonic
Wind Sensor. The 50.5 was designed to replace conventional sensors
for longer term unattended operation. There are no moving parts
with the 50.5 and the ouput signal maybe analog voltage, serial
or SDI-12. Each 50.5 is individually tested in the Met One wind
tunnel against an NIST traceable standard to insure quality performance.
Applied Technology Inc. of Colorado and MOI jointly designed
the new solid-state wind sensor using doppler ultrasonic measurement
1998 - EPA equivalency was awarded to MOI for the BAM 1020, which
led to expanded domestic and international sales of the BAM.
1998 - Responding to the EPA Speciation Network requirements, Met
One developed the SASS Speciation Sampler forming a joint venture
with Aerosol Dynamics. The success of the SASS was measured by customer
response. Met One provided over 85% of the intruments in
the Network. The instrument provided the user with benefits
that were unique compared to other particulate samplers. The SASS
was truly portable, could be installed by a single person with simple
user-interface at a lower cost.
2000 - The Aerocet 531 was introduced to the market. The Aerocet
531 combines particulate and mass measurements in a single small
hand-held instrument with easy to use data logging.
2001 - Design was completed on the new E-BAM, a portable Beta Gauge
that traces its calibration through the BAM 1020 to the EPA reference
standards. The E-BAM is completely portable and may be used with
solar panel and batteries.
2002 - The E-Sampler Continuous Particulate Monitor was introduced
and included a built-in data logger and a 47 mm changeable filter
media. The filter could be used for reference comparison. The E-Sampler
has a custom case and special tripod to make set-up super quick.
Climet Instruments meteorological product line was purchased in
this year and integrated with other instrumentation products at
Grants Pass. The Climet purchase provided Met One with some specialized
test equipment and product designs.
2003 - Met One put it's foot in the water with the introduction
of the Model 821 Water Level Sampler. The 821 uses differential
pressure to determine water depth and incorporates a unique purge
system to maintain operation even in silt-laden streams. A big advantage
of the Model 821 is the multiple monitoring ports.
MOI employs engineers and trained technicians to develop and support
old and new customers. Training is given throughout the year
to distributors as well as customers in the factory. Call
