1. FEATURES
* Combination of hot wire and standard thermistor,
deliver rapid and precise measurements even at low
air velocity value.
* Slim probe, ideal for grilles & diffusers.
* Air velocity : m/s, Ft/min, Km/h, Knot, Mile/h,
* Air temperature ( , )℃ ℉
* Air Temp. used thermistor sensor, fast response time.
* 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 of different
measurement environment.

( 3-2, Fig. 1 ) momentarily.
* Pressing the " Power Button " ( 3-2, Fig. 1 )
continuously and > 2 seconds again will turn off the
meter.
2)The meter can select 2 kind function as :
a. Air velocity/Temp.
d. Type K/J Thermometer
Pressing the " Function Button " ( 3-3, Fig. 1 )
continuously ( not release the button ), the Display
will show the following text in sequence :
Air Air velocity/Temp. measurement
tP Type K/J Thermometer measurement
Until the Display show the desired mode ( Function ),
just release the " Function Button " ( 3-3, Fig. 1 ), the
meter will execute this function with default.
