Air Flow Logger

AD-1641

Weighing Data

Air Flow(from A&D’sbalance/scale)(0 to 1.00 m/s)

Temperature

Humidity(0 to 60 °C)(0 to 100% RH)

BarometricPressure(500 to 1100 hPa)

Vibration(0 to 2000 Gal)

Not just a simple air flow logger, but the world’s
most versatile environmental data logger!
ISO
9000 CERTIFIED

Five Kinds Of Environmental Data
With One Device!?
Now you can precisely capture low-velocity air flows of 0 to 1.00 m/s –together with temperature, humidity, barometric pressure and evenvibration all at the same time – using nothing more than this single,
portable and easy-to-mount device!

Diverse array of possible applications
For constant monitoring of the wind speedof a containment enclosure, laminar flow
cabinet, etc.

For managing the environmental factorsthat affect the stability of high-precision
weighing instruments (e.g. microbalances)

For creating and/or studying environments
for nurturing delicate animals or plants

For controlling ambient conditions inlaboratories, workshops, industrialprocesses, etc.

And so forthAlarm for abnormal values (comparator function)
The AD-1641 lets you know by buzzer*1 as well as by display if the selected environmental
value (air flow, temperature, humidity or barometric pressure) has fallen outside the set
upper and lower limits for the selected period of time (3 seconds, 10 seconds, or at once).
This function is especially useful for ensuring the safety of containment systems.

Simultaneous logging of environmental and weighing data
When connected to an A&D balance/scale, the AD-1641 can save *2 mass values sent fromthe balance/scale while simultaneously collecting the five kinds of environmental data, allwith date and time of recording. There will no longer be the hassle of manually integrating
data from different devices for later analysis and documentation.

worth of continuous recording at a 15-minute interval

Quick data saving to a PC requiring no special software
The PC instantly recognizes the AD-1641 as USB storage. The data is stored in CSV format
and can be opened using spreadsheet software such as Microsoft Excel, allowing for easy
processing and graphing.

■ Real-time transmission mode
The AD-1641 can transfer environmental data (with or without weighing data) to a PC inreal time instead of saving it on the device itself.

Protector against dust & water (IP65) as well as 1.5 m
drop impacts
With the provided protective cover, the main unit of the AD-1641 becomes IP65 dust andwaterproof for use under tough conditions. It also absorbs impact shocks enough to avoid
breakage from falls from as high as 1.5 m.

Various display modes
You can choose to set the AD-1641 to display only two preferred data items instead of all
for easier reading and monitoring (primary data mode), and display data by trend graphs
instead of figures so as to intuitively grasp chronological variations or spot irregularchanges (trend graph mode).
