Introduction  
Congratulations on your purchase of the Extech EZ30 Thermo-Anemometer. The EZ30  
measures air velocity in five units of measure: feet per minute (ft/min), meters per  
second (m/sec), miles per hour (MPH), kilometers per hour (km/hr), & nautical miles per  
hour (knots). An internal Type K sensor allows the EZ30 to measure air temperature in  
Celsius or Fahrenheit units. The 16” (406mm) flexible gooseneck provides easy access  
for air velocity and temperature measurement in difficult to reach locations. This meter is  
shipped fully tested and calibrated and with proper use will provide years of reliable  
service.

Operation  
Meter Power  
1. Press the POWER button to turn the meter on. If the display does not switch on, check  
that a fresh 9V battery is installed.  
2. Press the POWER button to turn the meter off.  
3. The meter is equipped with an AUTO POWER OFF feature. The meter automatically  
shuts off after 15 minutes to conserve battery energy. To disable this feature, hold  
down the UNITS key while turning the meter on. “disAPO” will appear in the display to  
indicate that Auto Power Off has been disabled.  
Measuring Air Velocity and Temperature  
1. Place the sensor in the air stream under test.  
2. Read the Air Velocity and Temperature measurements directly on the LCD.  
3. To calculate Air Volume in CFM (cubic feet per minute) or CMM (cubic meters per  
minute) refer to the ‘Useful Equations and Conversions’ section.  
Selecting the Temperature unit of measure (oC/oF)  
Press and hold the UNITS key for 3 seconds to select the temperature unit of measure.  
The meter will beep twice and the display will indicate the currently selected unit of  
measure.  
Selecting the Air Velocity unit of measure  
Press the UNITS key to change the unit of measure for Air Velocity measurements. The  
display will reflect the current selection. A list of measurement units is printed in the  
specifications later in this manual.  
Data Hold/Backlight  
To freeze the LCD display, momentarily press the HOLD key. The 'HOLD' icon will appear  
on the LCD and the reading will remain unchanged. Momentarily press the HOLD button  
again to return to normal operation (the 'HOLD' icon will switch off).  
Press and hold the key for 3 seconds to turn the backlight on/off.  
Record and Recall MAX / Min Function  
1. To begin capturing the Maximum (MAX) and Minimum (MIN) air velocity and  
temperature readings, press the MAX/MIN key and the ‘RECORD’ icon will appear in  
the display.  
2. Now, use the MAX/MIN key to toggle the view from MIN to MAX to RECORD. The  
‘MAX’ or ‘MIN’ will appear along with the recalled reading for convenience. In RECORD  
mode, the meter will display the current reading but will continue to capture MAX and  
MIN readings.  
3. To return to normal operation, press and hold the MAX/MIN key for 3 seconds to clear  
and stop MAX/MIN recording. The meter will beep twice and the ‘MAX’/‘MIN’ and  
‘RECORD’ icons will switch off.

Maintenance  
Battery Replacement  
When the battery power falls low, the low battery icon  
will appear on the LCD. Replace  
the 9V battery by removing the Phillips screw on the battery compartment door and  
accessing the battery compartment. Ensure that the compartment cover is securely  
fastened when finished.  
Cleaning and Storage  
Wipe the meter and vane with a damp cloth as needed. Do not apply abrasive, solvents, or  
other cleaners to the surface of the meter or vane. Store with the battery removed and  
avoid extreme temperature and humidity.

Useful Equations and Conversions  
Volume Measurements  
To determine CFM (cubic feet per minute) or CMM (cubic meters per minute) in a duct, the  
area of the duct must first be measured (use the equations below). Then multiply an air  
velocity measurement by the area measurement to obtain CFM or CMM.  
Area equation for rectangular or square ducts  
Height (H)  
Width (W)  
Area (A) = Width (W) x Height (H)  
Area equation for circular ducts  
Area (A) = ꢀ x r2  
Radius  
Where ꢀ = 3.14 and r2 = radius x radius  
Cubic equations  
CFM (ft3/min) = Air Velocity (ft/min) x Area (ft2)  
CMM (m3/min) = Air Velocity (m/sec) x Area (m2) x 60  
NOTE: Measurements made in inches  
must be converted to feet or meters before using the above formulae.
