Headquartered in Waltham, Massachusetts , Extech Instruments is one of the largest suppliers of test and measurement equipment worldwide. Founded in 1971, Extech is known not only for the innovation it brings to the test and measurement marketplace by providing instruments with unique combinations of features that make them highly useful and very convenient multi-functional devices, but also for the depth and breadth of its product lines. Extech meters are distributed worldwide through a network of leading representatives, distributors and OEMs. The company is ISO 9001 2000 certified.

Though many of the products they offer have evolved or changed over the course of the 37 years Extech has been in business, one thing has remained the same- the Extech Advantage. There are three dynamic and equally important components to the Extech Advantage: Support, Innovation and Selection.

 Support - Customer service is our number one priority. Nothing is more important to us than making sure you receive the very best in customer support and service.

Innovation - Extech Instruments is proud to have earned a worldwide reputation for innovation. Our award winning proprietary products are a driving force in helping us build our brand and providing more product innovation to the marketplace.

Selection - The breadth of our product line is supported by a depth of products within each category, a selection of products that is unparalleled in the test meter industry. For every application there is an Extech solution.

Extech Products  

Extech offers over 300 test and measurement instruments in more than 14 product categories, including multimeters, clamp-on meters, tachometers, light meters, sound meters and meters to test temperature, airflow, humidity and water quality. Many of the meters are engineered to be multifunctional devices including either a patented, built-in, non-contact InfraRed thermometer or a built-in voltage detector. Along with the powerful and exclusive built-in features and functions, Extech offers the right piece of test equipment for any application.

Multimeters

-Used to measure voltage levels. The multimeter is the primary diagnostic instrument for a technician working on equipment that requires electrical power to function. Fluctuating voltage levels, such as spikes and sags, in the power provided by the utilities, can damage equipment and cause unscheduled downtime. The usefulness of multimeters is further enhanced by the additional functions we now add to the multimeter. The addition of diode and capacitance function s is now quite common. More recently, we have added temperature measuring capabilities with type K thermocouples and our patented built-in infrared technology. Another new enhancement addresses safety issues by placing non-contact voltage detectors right into the meter, a function that lets the user quickly check for the presence of voltage before proceeding to a contact test.

Clamp Meters

- A favorite for plant maintenance professionals and HVAC technicians, the clamp meter is used to measure electrical current flow to a device with the advantage of not having to shut down the piece of equipment being tested. A motor drawing excessive current is operating inefficiently, heating up, and subject to premature wear or failure. As with the multimeter, we have sought to add useful features to the clamp meter. A true innovation can be found with the addition of the infrared thermometer into the clamp. This unique function lets a user scan an electrical panel for the hot spots that indicate a bad or failing connection. The non contact voltage detector also has a place in the clamp as a means to enhance user safety.

Tachometers

-Used to test the speeds of motors and conveyor belts. Excessive operating speeds can cause components to overheat and can lead to premature wear or failure, both causing costly production line shutdowns. The incorporation of the infrared thermometer into the tachometer gives the user the ability to scan a bank of motors and quickly isolate the one that may be running hot. This is yet another patented offering exclusive to Extech.

Sound Meters

-Used to test noise levels for compliance to noise regulations. Hearing loss in workers is a serious affliction that occurs over time on a cumulative basis. Employers assume responsibility for their employees at their workplace and limiting the exposure to loud noises falls under their responsibility. Non compliance leads to fines and employee lawsuits. We offer dosimeters, sound level meters and the only area sound monitor with integrated over sound limit LEDs.

Humidity and Temperature Meters

-Used to monitor humidity levels for conditions favorable to mold growth and static electricity. Mold causes spoilage in goods and health problems with employees. Uncontrolled static electricity brings component failures and can even cause explosions in some cases. Our most recent addition is a real time graphical chart recorder that gives an easy to read visual chart of the temperature and humidity changes within a room.

Airflow Meters

-Used to measure airflow in HVAC vents and fume extraction hoods. Insufficient flows can lead to employee health problems and lost productivity. Contractors can benefit greatly from the inclusion of the infrared thermometer into the anemometer. We have incorporated the IR to let the user take measurements without having to pull out a ladder, a definite safety improvement and time saver.

Water Quality Meters

-Used to monitor discharge fluids for compliance to clean water health standards. Non compliance leads to fines and sanctions. Any industrial operation that uses water in a process must check the quality of that water before it is discharged. With the Exstik ® product line, we have a product for all your water quality measuring needs.

Light Meters

-Used to measure light levels. With the concerns of global warming coming to the forefront, light meters are a valuable tool in ensuring that appropriate lighting levels are maintained while reducing power consumption. Extech offers light meters for spot check or with recording features for over time analysis of lighting levels.

Resistance Meters

-Used to make sure that equipment is properly grounded. Poorly grounded equipment causes power quality issues and can also be the cause of fatal accidents. Whether you need to measure milliohms or megohms, Extech has a solution for you.
