With a probe on a cord, these meters access hard-to-reach places in duct. They display airflow and temperature simultaneously and can show airflow measurements on multiple scales, such as fpm, mph, and knots.
Use the RS-232 port to transmit data. For a USB connection, you'll need a USB adapter cable (sold separately).
Tube meters have a probe that telescopes to 3 ft. to reach into narrow openings.

Monitor the health of pumps, engines, and other rotating equipment from your wireless device. These battery-powered sensors measure velocity, acceleration, and temperature to help identify potential problems related to balance, alignment, and lubrication. Good for daily maintenance checks, they're battery powered and magnetic, so you can stick them on a machine, take a reading, and move to the next machine. They send readings using Bluetooth, which you can review in the field or offsite.
Install the app on your device and create profiles for multiple pieces of equipment—once created, you won’t have to enter information each time you want to do a maintenance check. Based on your machine profiles, the app will set default alarm thresholds. It will also recommend courses of action.
Sensors and replacement chargers cannot be sold to certain regions due to local energy efficiency regulations.

Motion-Measuring Modules for Development Boards
![](/prerenderstable/mvPRE/contents/gfx/imagecache/818/8184n12-f@halfx_me5gr_1718024020.png?ver=imagenotfound)
Measure your device's acceleration, rotation, or orientation. These modules gather data over time and track movement, which can help improve performance, debug issues, and calibrate your components. Solder them onto a development board. To connect them to your device, solder on a wire or header. For a solderless connection, use a Qwiic cord (not included).
An accelerometer measures the rate at which your device is speeding up or slowing down. A gyroscope measures how fast your device is rotating. A magnetometer measures your device's orientation.

These switches detect magnetic objects—or objects with a magnet attached—through non-magnetic walls. They’re often used to count magnetic items on a conveyor belt that are too far for other proximity switches to detect and in food plants to track cleaners through stainless steel pipe. Producing a PNP signal output, these switches are commonly used with programmable logic controllers (PLCs). Resistant to dust, heat, and vibration, switches will stand up to harsh environments. Magnets are sold separately.
Maximum sensing distance in the table below represents switches used with the magnet shown. Sensing distance will vary depending on the magnetic strength of the object your switch is detecting.
