TTK 72 E COMFORT DEHUMIDIFIERPerfect dehumidification for large living and office spaces Absolutely low-key on the outside, the TTK 72 E has enormous power reserves. With up to 24 litres per day the ideal partner when it comes to keep living and office spaces of about 50 m² reliably dry. Through the built-in LED, the unit indicates the current humidity status in the room. The colour LED on the TTK 72 E instantly indicates if the room humidity is okay: whether the LED on the front of the unit is blue, green or red depends on whether the humidity is above or below 55 %. The LED is blue when the room humidity falls below 55 %. It is green when the humidity is within the optimum range between 55 and 70 %. Red means the room humidity has increased to above 70 %.

TTK 53 E COMFORT DEHUMIDIFIERConvincing dryer performance paired with functional elegance The TTK 53 E provides all functions a modern comfort dehumidifier needs. However, it also has another convincing and interesting extra function. On the front, there is a colour LED so that you instantly know if the room air humidity is okay. The functional design of the TTK 53 E fits any style of furniture. With a dehumidification capacity of up to 16 litres per day, it keeps heated rooms of up to about 30 m² reliably dry. On the easy-to-clean control panel with digital display you can select from the following dehumid­ification modes: automatic operation with a preset humidity of 55 %, hygrostat-controlled automatic dehumidification system with target value preselection between 30 and 80 % RH in steps of 5 %, continuous operation as well as a ventilation function. The colour LED indicates if the humidity is okay

Dries, dehumidifies and indicates the humidity levelDeclare war on unhealthily humid room air in your personal environment. The modern TTK 33 E dehumidifier in an appealing cube-shaped design puts an end to high humidity levels in rooms. As a mobile dehumidifier with a practical carrying handle, it improves the air quality and provides a better room climate for your well-being or for working. A hygrostat-controlled automatic dehumidification system reduces the room humidity in living and business rooms, offices, shops, unheated conservatories, basements and garages to a target value that can be preset to a value within the relative humidity range of 30 % to 80 %. With a sound level of only 43 dB(A), the dehumidification function is pleasantly quiet even at the highest of the two selectable fan speeds. For this reason, the TTK 33 E can also be recommended for use in the bedroom or at the workplace without impairing sleep or work.

A humidity indicator card (HIC) is a card on which a moisturesensitive chemical is impregnated such that it will change color when the indicated relative humidity is exceeded. This is an economical way to quantify relative humidity levels inside sealed packaging like moisture barrier bags.

Certain plastic encapsulated surface mount devices (SMDs), if not handled properly, can incur damage during the solder reflow attachment process to printed circuit boards (PCBs). In order to prevent damages, the moisture sensitive product is typically baked before packing. After baking, the product is placed inside a DryPack bag along with predetermined amount of desiccant and a humidity sensitive indicator card (refer to JEDEC JSTD033C). The vacuum sealed bag is labeled and placed in a pizza box carton.

The easy-to-use Vaisala HM40 is a compact and portable humidity meter that provides reliable measurements in a wide range of applications. It is the ideal spot-checking tool for everything from structural moisture measurement and air conditioning systems to humidity measurement in industrial production processes and life science applications. The HM40 has a large, user-friendly graphical display and easy-to-use push buttons. In addition to relative humidity and temperature, the HM40 provides five calculated humidity parameters, all of which are available in metric and non-metric units. Included in delivery is a certificate of calibration which is traceable to national and international standards. There are four different models available: HM41, HM42, HM45, and HM46. Calibrating the HM40 is easy. The meter or the probe can be sent to a Vaisala Service Center for recalibration. Alternatively, calibration can be completed on site by users with a humidity reference such as the...
