This thermohygrometer shows WBGT index (heat stress index) or absolute humidity, and a difference between the measured and recommended values. It helps you create a comfortable environment.
■ Displays a difference between the measured and recommended values of temperature or humidity.
■ In influenza mode, it displays absolute humidity as a measure to prevent seasonal influenza.
■ In heat stress mode, it displays WBGT index (heat stress index) as a measure to prevent heat stroke.
■ Sliding a mode switch changes the mode to heat stress mode or influenza mode.
■ Equipped with LED light and buzzer alerts
■ Use a hook for wall mount, a stand for desktop
■ Influenza mode
In this mode, absolute humidity as a guideline for prevention of seasonal influenza and the difference between the relative humidity of the comfortable environment and the current one are shown.
The difference indicates how many percents (%rh) the humidity needs to be increased.
One of four colored icons is displayed based on absolute humidity.
* Comfortable humidity is set as 10 g/m3 regardless of temperature. Note that this threshold is not in a complete safe status but a cautious status.* Humidification may induce condensation or occurrence of molds. Consider stopping the humidification in such case.
* The difference is displayed as 0%rh if the absolute humidity is 10 g/m3 or more.
■ Heat stress mode
In this mode, WBGT index as a guideline for prevention of heat stroke and the difference between the temperature of the comfortable environment and the current one are shown.
The difference indicates how many degrees (°C) the temperature needs to be lowered.
One of four colored icons is displayed based on WBGT index.
* Comfortable WBGT index is set as 27°C regardless of humidity. Note that this threshold is not in a complete safe status but a cautious status.
* Heat stroke may occur even in a safer status if you exercise heavily.
* The difference is displayed as 0°C if the WBGT index is 27°C or less.
■ Caution
Each value of a guide to a comfortable environment is a rough estimation to help you consider your health management.
Indicated alerts may vary from an official alert from a government.
■ What is absolute humidity?
Absolute humidity is one of the units for measuring humidity, which is defined as mass of water vapor contained in a unit volume of air.
According to a report by Dr. Makoto Shoji, absolute humidity strongly correlates with seasonal influenza and the epidemic begins when the absolute humidity is below 10 g/m3.
PC-5500TRH helps your effort to prevent influenza.
| Absolute humidity | Air dryness and the risk of the seasonal influenza epidemics |
| 7 g/m3 and under | Extremely dry. The risk is at highest. |
| 8–11 g/m3 | Dry. The risk is high. |
| 12–16 g/m3 | Wet. The risk is low. |
| 17 g/m3 and up | Extremely wet. The risk is at lowest. |

■ What is WBGT index?
WBGT, stands for wet bulb globe temperature, is an index introduced from three elements related to biological heat balance: temperature, humidity
, and heat radiation. It is usually calculated from dry bulb temperature, wet bulb temperature, and black globe temperature, which requires professional techniques and devices with a limitation to install them.
PC-5500TRH easily calculates WBGT from temperature and humidity based on a guideline by Japanese Society of Biometeorology.
Make use of this device with WBGT to prevent heat stroke.
| 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 (25°C or lower) |
Risk during very vigorous physical activity | Low in risk basically, but high in risk when doing vigorous exercise or heavy labor. |
