This thermohygrometer displays estimated WBGT index and absolute humidity (influenza index) as a bar in addition to temperature
and humidity to help you maintain the comfort ambient air. Alarm for WBGT is equipped.
■ Displayed content:
■ Heat stress checker
Displays WBGT as a cautious level of five steps.
WBGT | Type of risks in relation to physical activity | Remarks | |
Danger | 31°C or higher | Risk during any physical activity | Risk of occurrence is high for the elderly, even when they rest. Avoid going out and stay in a cool room. |
Severe warning | 28 to 31°C | Avoid direct sunlight outdoors and watch for any rise in room temperature indoors. | |
Warning | 25 to 28°C | Risk during moderate to vigorous physical activity | Take adequate rest regularly when exercising or doing vigorous work. |
Caution | 21 to 25°C | Risk during very vigorous physical activity | Low in risk basically, but high in risk when doing vigorous exercise or heavy labor. |
Safe | 21°C or lower | Safe |
WBGT is...
an acronym of wet bulb globe temperature, which is an index introduced from three elements related to biological heat balance: temperature, humidity, and heat radiation.
PC-7980TRH calculates WBGT from temperature and humidity based on a guideline by Japanese Society of Biometeorology.
■ Influenza checker
Displays absolute humidity as a cautious level of three steps.
Absolute humidity | Environment for viruses | Countermeasures | |
Warning | 7g/m3or less | Suitable for viruses. High risk of infection. | Increase temperature and humidity by using a humidifier |
Caution | 8 to 11 g/m3 | Viruses can survive. Be cautious of infection. | Avoid a decrease in temperature and humidity. |
Safe | 12 g/m3 or more | Viruses cannot survive. | Keep the temperature and humidity at a reasonable level. |
Absolute humidity is...
mass of water vapor contained in a unit volume of air, which can be used as a barometer of the probability of epidemics of seasonal influenza according
to a report of "Absolute humidity as a deterministic factor affecting seasonal influenza epidemics in Japan", Makoto Shoji et al., 2011.
■ Temperature, humidity, and their maximum and minimum
Pressing "max" or "min" button switches the display from current temperature/humidity to today's maximum/minimum and yesterday's maximum/minimum.
|
At 0:00 midnight today's data of maximum and minimum changes to yesterday's data, and the previous yesterday's data is erased automatically.
■ Clock, WBGT, absolute humidity
Pressing "mode" button switches the display from clock to WBGT and absolute humidity.
Clock | WBGT | Absolute humidity |
12/24-hr system switchabe | Unit: °C | Unit: g/m3 |
■ Alarm clock
Can be used as an alarm clock to ring at the set time every day.
■ WBGT alert
A buzzer sounds when the WBGT exceeds the set level.
■ Caution
- Each value of a guide to a comfortable environment is a rough estimation to help you consider your health management.
It does not directly protect you from heat stroke or influenza.
- Indicated alerts may vary from an official alert from a government.
■ Batteries included initially are for test use and may last shorter than their expected life.
