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.
