About Flow Control Valves
Also known as cylinder speed controls, flow control valves let you control the extension or retraction speed of your air cylinder. They regulate airflow as it passes from the valve's inlet to its outlet. Air flows freely in the opposite direction.

Airflow Meters
Liquid meter is also known as a manometer.
Swinging vane meter is for low-velocity airflow. It is commonly used in spray booths and exhaust hoods.
Remote-Reading Airflow/Temperature Meters
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. Also known as anemometers.
Fan meters are also known as vane meters. Those with a built-in surface temperature thermometer also measure the temperature of hard-to-reach surfaces. Mini fan meters have a fan at the end of a telescoping probe. You can also use them to measure humidity.
Pilot tube meters measure a wider airflow range than other meters. They also measure differential pressure.
Telescoping tube meters are also known as hot wire meters. They have a probe that telescopes to reach into narrow openings.
Meters with an SD card data connection store timestamped readings on an SD card in Excel format, for easy datalogging and PC transfer. Meters with a 3.5 mm audio data connection can transmit data through a USB connection using a USB adapter cord (sold separately, except for Style C). Meters with a mini-USB and micro-USB connection type transmit data to your PC through the included cable.

Airflow/Temperature Meters
These versatile meters display airflow and one other measurement simultaneously. They’re also known as anemometers or vane meters. They can show airflow measurements on multiple scales, such as fpm, mph, and knots.
Foldable fan meters are small enough to fit in your pocket when closed, then extend to 9” when unfolded.
Meters with a 4” blade diameter give you more accurate readings on large HVAC ducts than meters with smaller blades.

Contaminant-Free Smoke Generating Pellets
Detect airflow and leaks in places with sensitive electronics, such as server rooms. The smoke from these pellets contains only trace amounts of chloride, so it won’t cause electronics to corrode. Ignite them to create a short burst of smoke.
Smoke Generating Candles
Light the wick to produce a short burst of smoke to detect airflow and leaks in HVAC systems.
Use candles with two wicks to extend burning time. Link the wicks with included cable ties. When the first wick burns down, the second lights. Each wick you link adds 3 minutes of burning time.
Smoke Powder
Release a burst of floating powder to detect airflow and leaks in HVAC systems, no flame or ignition source required.
Squeeze-bulb powder creates a denser cloud than squeeze-bottle powder, so you can more clearly see air movement. It requires a rubber squeeze bulb (sold separately) to operate.
Pressure Indicators
These pressure indicators display a green color when the pressure of your compressed air line reaches 15 psi.
Panel-mount indicators mount through a hole in your wall, tank, or panel and secure with a nut.
Indicators with window allow for easy viewing of indicating color.

Indoor Environmental Meters
Measure airflow, light, humidity, and temperature with a single, pocket-sized tool. These meters have built-in sensors that can detect multiple environmental factors in your plant or office. This helps you maintain safety compliance and track energy efficiency. A data hold function lets you freeze a measurement on the screen, giving you time to write it down. Additionally, they have the memory to store your high and low measurements. These meters are also known as hygro-thermo-anemometers.
They’re CE marked as compliant with European health, safety, and environmental standards.
Plug in an optional thermocouple probe to measure the surface temperatures of hard-to-reach areas, such as duct walls.
