Number 2 is where I have had difficulty and why I originally came to this fine forum. I have already gotten some nice results with the cobalt-chloride paper. Wet thermal paper, or cobalt chloride paper placed in the microwave oven will give a nice visual record of the em-field distribution. I have a methodolgy for number 1 that other research groups have used succesfully. I need to know two things: 1) The em-field distribution, specifically the location of "hot spots" 2) The electric field orientation in a given hot spot. I thank you all!įor the sake of those posting, I would like to clarify what I am looking for. RE: Microwave oven electric field mapping Higgler (Electrical) 3 Aug 07 14:44įirst of all, thanks to all of those who have offered their thoughts and advice. I am not so experienced with all this RF stuff. I was thinking of putting the pencil lead in a test tube with an inert gas, but I don't if that will help. I am looking for a slightly less dramatic test. You stick it in the microwave and you know its parallel to the field when it starts making a loud buzzing noise and spits flames and sparks. The method that works at the moment is a piece of pencil graphite. My problem is checking the field orientation. Locating the nodes isn't such a problem, that can be done with thermal paper or some neon bulbs. Any simulation would thus have to be verified experimentally, so we mind as well skip it. Cobalt chloride weather indicator how to#We are trying to do an experiment and we need to know with some certainty where the nodes are so we know how to arrange our set up. Cobalt chloride weather indicator software#I am aware that there is modeling software for this sort of thing, however that won't help me. It had regular wire leads and indeed the leads/electrodes I realize don't make much difference, the gas will glow whenever the bulb is in a peak. Keep container tightly closed.I found an old neon bulb and tried it out. If experiencing respiratory symptoms: Call a POISON CENTER or doctor/physician. Immediately call a POISON CENTER or doctor/physician. Remove contact lenses, if present and easy to do. IF IN EYES: Rinse cautiously with water for several minutes. IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing. IF ON SKIN: Wash with plenty of soap and water. In case of inadequate ventilation wear respiratory protection. Contaminated work clothing should not be allowed out of the workplace. Use only outdoors or in a well-ventilated area.
