New Digital Temperature
and Humidity Meter TH804

Great Tool To adjust your humidifier or air conditoner!

Avoid damp rooms that promote mold!

Most experts recommend an indoors air humidity level between 40 and 60% as most comfortable. Too dry air can strain the respiratory tract, while high humidity levels promote the growth of mold and germs in the walls.

Many people use humidifiers during the dry winter months. But does your humidifier work right? Does it provide enough moisture, or too much? Measure it with the TH804 meter!

This meter will allow you to check the humidity level and temperature quickly. The sensor is located at the lower edge of the meter, for best air circulation and fast readings. Place the meter in a room and after 3-5 minutes it will give you a stable reading of the current conditions. You then can use the readings to adjust the humidifier. If the meter reads "dry" it might be good to switch it on, if it reads "wet" you should switch it off to avoid mold.

Use this meter to monitor heating and air conditioning systems. Do they come on at the right time? Are there unwanted cycles or variations? This recorder will show the exact climate and will allow you to improve the control and to balance the system. It works down to -40 degrees, and therefore is great to monitor freezers and cooling containers during shipment.
