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.
