1. FEATURES
* Introduction :
WBGT ( wet-bulb globe temperature ) was developed
as a monitoring basis at US military training camps
and became widespread for the use in workplaces and
sports situation It is suggested in the international
standard ISO 7243, OSHA ( US Occupation Safety ),
Japan Society for Occupational Health and the SMA (
Sports Medicine Australia ) in establishing the
permissible heat exposure limits in health , sports or
other physical activities.
* Measurement : WBGT value ( Indoor/Outdoor Wet bulb
globe temperature ), Black globe temperature, Humidity,
Air temperature, Wet bulb temperature, Dew point Temp..
* Adjustable WBGT alarm setting, if the WBGT value over
the alarm threshold, the buzzer will sound along with
the flashing Display.
* Using to control and monitor of physical activity in hot
environment to limit the danger of heat related
injuries.
* Globe temperature measurement use the Pt sensor,
high accuracy.
* Fast humidity measuring response time.
* Direct measurement of the radiation effect with
a brass black ball in 75 mm dia.
* Sensor protecting mechanism.
* 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.

Circuit Custom one-chip of microprocessor LSI
circuit.
Display LCD size : 52 mm x 38 mm
LCD with green backlight ( ON/OFF ).
Measurement * Wet bulb globe temperature ( WBGT )
@ Indoor/Outdoor
* Black globe temperature ( TG )
* Air temperature ( TA )
* Wet bulb temperature ( WB )
* Humidity
* Dew point temperature
WBGT formula Indoor/Outdoor and no sun :
*Wetbulb WBGT = ( 0.7 x WB ) + ( 0.3 x TG )
globe Temp. Outdoor and full sun :
WBGT = ( 0.7 x WB ) + ( 0.2 x TG ) + ( 0.1 x TA )
