1. FEATURES

* One meter can accept two probes :

Hot wire anemometer probe and Humidity/Temp. probe

* Combination of hot wire and standard thermistor,

deliver rapid and precise measurements even at low

air velocity value.

* Slim hot wire probe, ideal for grilles & diffusers.

* Air velocity : m/s, Ft/min, Km/h, Knot, Mile/h,

* Air flow ( CFM, CMM ) measurement.

* Air temperature (

℃

℉

)

* Air Temp. used thermistor sensor, fast response time.

* Fast humidity measuring response time.

* Humidity/Temp., Dew point Temp., Wet bulb Temp.

* Type K, Type J thermocouple thermometer.

* Real time SD memory card Datalogger, it Built-in Clock

and Calendar, real time data recorder , sampling time set

from 1 second to 3600 seconds.

* Manual datalogger is available ( set the sampling

time to 0 ), during execute the manual datalogger

function, it can set the different position ( location ) No.

( position 1 to position 99 ).

* Innovation and easy operation, computer is not need

to setup extra software, after execute datalogger, just

take away the SD card from the meter and plug in the

SD card into the computer, it can down load the all the

measured value with the time information (

year/month/date/ hour/minute/second ) to the Excel

directly, then user can make the further data or graphic

analysis by themselves.

* SD card capacity : 1 GB to 16 GB.

* LCD with green light backlight, easy reading.

* Can default auto power off or manual power off.

* Data hold, record max. and min. reading.

* Microcomputer circuit, high accuracy.

* Power by UM3/AA ( 1.5 V ) x 6 batteries or DC 9V adapter.

* RS232/USB PC COMPUTER interface.

* Separate probe, easy for operation.

* Applications : Environmental testing, HVAC, Air conveyors,

Flow hoods, Clean rooms, Air velocity, Air balancing,

Fans/motors/blowers, Furnace velocity, Refrigerated case,

Paint spray booths, Humidity/Dew points Temp.
