INTRODUCTION
Congratulations on the purchase of your Digital
Hygrometer & Thermometer.
Maintaining the correct temperature and
humidity levels is beneficial to us and our homes.
Room Humidity is best maintained between 45-
55%RH where the health risk from viruses, fungi
and dust mites are minimised.
If the Hygrometer/Thermometer displays a
reading of 45% or less this indicates that you
may need a humidifier to increase the moisture
content of the air.
If the Hygrometer/Thermometer displays a
reading of 55% or more this indicates that you
may need a dehumidifier to remove excess
moisture from the air.
