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.
