Battery to extreme temperatures
Lithium AA Batteries - for extreme conditions
Delivers the power down to -55 º C degrees
Sometimes it is extremely cold. Even at minus degrees starting crystals in LCD displays become sluggish and difficult to see.
Good, fully Alkaline batteries can easily -20 º C, up to -30 º C. But then, when the batteries are getting discharged, or the temperature drops even more, then it will be difficult. That is when the lithium battery keep running .. They have a number of characteristics which may make them worth the money. Lithium batteries can be stored a long time. The loss during storage in 20 º C only 1% of
capacity per year. At the lower storage temperature less.
- Lithium manganese dioxide
- Working range from minus -55 º C to + 85 º C
- NOTE! Do not be exposed to temperatures above 100 º C

Miljön är viktig
Det finns många sätt att värna miljön. Safecast är medlem i elektronikåtervinningsföreningen.
Eftersom uttjänta elektroniska produkter är farliga för miljön är det viktigt att de samlas in och återvinns på rätt sätt. Det är viktigt att produkterna lämnas till återvinning i ett så helt skick som möjligt. Sortering och demontering sker för hand och arbetet försvåras om produkterna är trasiga eller nedsmutsade. Genom vårt medlemskap garanteras att produkterna blir omhändertagna enligt naturvårdsverkets regler när de lämnas till återvinning.
Ett annat sätt att värna om miljön och plånboken är att minska på elförbrukningen. Det kan du också göra...
Bra för såväl samvete och den egna plånboken. Eco-eye är en trådlös energimonitor som för ca 1000 kr ger dig möjligheten att spara 10-25% av din tidigare elförbrukning, varje år - bara genom att du får bättre kontroll på hur mycket el du förbrukar just för tillfället. Undersökningar i England har visat på besparingar på upp till 25%!

The weather impacts on construction sites
 A very interesting study for those considering
costs and quality of new construction. Possible
rainfall accounts for one hours direct production
construction workers per day.
There is considerable scope for improvement. When you build
in April and May, you get more for your money.
Quote from the report: "... the weather affects construction output to a large extent. The weather impact
on site depends on the size of the construction site, at what stage you are, the season
and weather variation from year to year. Working in all the days lost in the pure
productivity for each construction workers on average 1 hours per day at the precipitation, 15 minutes
because of temperature and 7 minutes at high wind speeds. On average, the crane is stationary
almost 21 days per year, almost two days per month.
However, one should bear in mind that these data apply only to productivity reduction and not the
extra work arising from adverse weather conditions. By making use of
data presented in the paper, you can plan for any production-free days ."...

Current weather affects almost everything, the weather is also very local

Current weather affect |
Because it rains in the country next door, it is not safe you also get some rain. Therefore, the availability of good local data is an absolute must to make accurate statistics and safe prediction,
We sells weather stations to private individuals and companies that have discovered this.
When large values are at stake, you can go to safer answer the eternal question of how the weather will be. There are already several players including SMHI but not yet come so far in this field. |
