    NIR Light Moisture Meter

    I have come across the NIR (Near Infra Red) light moisture meter manufactured by GreCon (http://www.grecon.de/english/products/ir/index.htm) and CHINO (http://www.chino.co.jp/english/products/07_IR-M1000.htm). As far as I'm concerned most non destructive moisture meter (pinless) get use of the...

    VA & Watt Confusion

    so is this "Sqrt(3)" kind of constant like "e" or "pie"? if so what is it actually called? Cheers.... and by the way even I multiply my VA with 1.73 it's still smaller than 22kW, so what else can I do? Thank you.

    VA & Watt Confusion

    First what do you mean by "nameplate power"? and what are Irms and Vrms and how can I get those readings? Afterall where can I get the real power reading? Thank you very much.

    VA & Watt Confusion

    I have a motor with 22kW (I presume this is the power of the motor), I measured the current actually goes through it with a clamp meter and get a reading 17A. The voltage which sourced from a generator is 415V. So I get the Apparent Power reading 17x415=7055VA (7.05kVA). By definition Power...

    Measuring Moisture Content in Wood Log/Trunk

    That's very helpful, thanks a lot. Just wonder if there's any chance you will have the related ASTM document? As I'm not able to access from my university network now so downloading the document cost me some fortune. Thanks again for your help boo1, and all the guys!

    Measuring Moisture Content in Wood Log/Trunk

    That's indeed the most reliable way I know (oven weighting) but it takes time and too much effort which we could not justify the cost. So we need something else quick and effective, such as electric meters. The thing is there's too many choices in the market which can be quite confusing.

    Measuring Moisture Content in Wood Log/Trunk

    I am researching on a way to measure the moisture content (MC) in the wood log/trunk as supplied but yet still struggling to find a best solution. I want something quick and effective, such as an electrical moisture meters but have not found an appropriate meters for such application. Can...
