 Slim & compact & new feature is with it in 2008 'spring
 I participate in -6% of teams.
 I promote product development for carbon dioxide reduction.

Product good point

■ I understand an electricity bill to spend in one hour immediately!
  I calculate automatically approximately 12 seconds later and display the predicted value of the electric bill for one hour after start of measurement

 Measurement, indication of <four >

 ・Electric bill (I calculate for 22 yen/kWh)

 ・Amount of used electricity

 ・CO2 discharge

 ・Electric bill predicted value (yen / time) for one hour

■ Every one such as an air-conditioner, a refrigerator, a PC understands an electric bill, and the consciousness of the saving increases

■ 23 millimeters of thickness. I feel fine in slim!

■ The outlet part is foldable

Carbon footprint (breakdown according to the use) from the home

■ I examine a CO2 discharge of the household electrical appliance at an eco-watt, and let's keep prevention of global warming in mind!

Source) greenhouse gas inventory office "greenhouse gas discharge data of 1990-2005 year in Japan"

Indication item

 Electric bill → CO2 discharge for electric bill → one hour
 → Cyclic displays use electric energ
y for three seconds.

 If one of the indication becomes 999, all indication stops
 I do it. In addition, a measurement stops if electricity time is 999 hours,
 Each indication flashes on and off.

 Depending on an electric appliance to connect because I use simple method for measurement
 An error may occur for the result of a measurement.

I will compare it at an eco-watt

■ Please make use of an eco-watt for "comfortable energy saving life" in "your wisdom"
  I think that various comparisons are possible elsewhere

The household electrical appliance (TV) of 1. new model has a type getting "an economy in power consumption mode".
  I will compare it in ON/OFF of the economy in power consumption mode how long consumption is different.

2.I will check the consumption electricity of the refrigerator of the errand now.
  Again of the opening and shutting of the door is, and change the number of times and setting temperature (the strength and weakness), and let's compare difference in consumption electricity.

3.As for the PC of the desktop type, a monitor (CRT in particular) uses electricity than the main body more.
I will compare a difference in ON/OFF of the monitor.

4.When I use the cover of the heating toilet seat, I will compare a difference when I closed it when opening out.

5.When garbage is clogged up, there may be so difference in the vacuum cleaner.

Eco-watt use example

■ Civic actions for the prevention of global warming such as cities, towns and villages

An example: Kagoshima-shi, Yamaguchi Otsu-shi Fujisawa-shi Kodaira-shi Asahikawa-shi

 To turn Kagoshima-shi to the citizen; the free rental of the eco-watt (simple model electric energy indicator)
 I go. In combination with the environmental household account book which a city distributes about an environmental problem
 I learn it, and the practice of an eco-friendly lifestyle seems to be aimed at.
 I perform the rental of the eco-watt in other many local governments.

■ I use an eco-watt for employee education in the general company

An example: Than Gunma Company S general affairs department environment security room T

 As a tool to have an employee raise energy saving awareness as an action to the environmental moon interval
 I am used experimentally.


 1.I insert an eco-watt in an outlet

 2.I insert the plug of the electric appliance in an eco-watt

 3.Indication starts automatically

Remarks ・Depending on an electric equipment product to connect because use simple measurement system for result of a measurement an error
 It may occur
・Electricity cannot measure 5W or less (wait electricity)
・The voltage calculates 100V, the power factor by fixation to 1 (100%)
・The ban on use (a cause of an electric shock, a fire, the trouble) by the hand which I got it wet with water, and got wet
・I calculate the CO2 discharge (kg-CO2) based on a following calculation type
 Electric energy (kWh) X CO2 emission coefficient 0.555 

After the product of this place had order it; by shipment,
To have you understand that there is possibility to take time beforehand,
I ask.

In addition, is dispatch; a visitor of the product hope before an order beforehand to our store
