Can I view particles that range from 1um-5um? Can the software be used to measure accurately at that scale?

Yes, I routinely do that, and is the reason I bought the scope. I prepare dispersions of micronized materials for some of my products. My scope came with a calibration slide that has a metallized 50 scale. The human red blood cell is around 7 in diameter and are easily resolved at 1000 X. Measurements can be done using that scale calibration with the software, to about the accuracy of a good eyepiece micrometer. How accurate? That depends on the operator. There are more accurate ways of measuring particle size, such as laser scattering, but for routine characterization of industrial materials, the microscope software is adequate. The 2,500X magnification is not available for the camera, but that image is around the diffraction limit for a 1 particle, anyway, and not much good.

Yes, It Will Give You Results In PPM. Detection Range Is 0.05- 1.0 PPM. Thank You

I bought those too, the readings with the no-calibration strips still came out as 0.1's almost all the time with occasional 0.2's just like the first set of calibrated strips that I had bought with the meter originally. I'm an engineer and don't know exactly how they do it, but nanoscale manufacturing these days is doing amazing things so maybe the calibration sample is on the strip sub-microscopically and we simply can't see it. Just follow the instructions and be happy.

Hello there. To answer your question, no the mean particle size is NOT less than 100 nm. I searched for a few days to find a product that had a particle size of LARGER than 100nm. If you scroll down, under "product description" it states: "Produced from naturally occurring zinc ore, super purity (free from other metals). Cosmetic grade particle size 200-1000 nanometer (nm) or 0. 2-1 micrometer)."

My dial micrometers show 1.660<1.665. They are not perfectly round. Hope this helps.

The one I received was pretty close about 0.2 if I remember correctly. It is not really an issue though as it comes with chemicals to mix calibration solutions. You just need to mix it with distilled water.

I have one of these. I use it TI monitor the effectiveness of my RO filter module. It works great and it is cheap. Since I am not a testing lab, I can not say that it has 1 ppm resolution, but I can tell you it very well may.

the 1100 pro does &gt;0.5 microns and &gt;2.5 (both readings) one is on the left side and one on the right side. http://dylosproducts.com/dcproforairp.html or http://dylosproducts.com/ornodcproair.html DC1100 Pro has all the features of the standard DC1100 but with increased lower sensitivity - detecting particles down to 0.5 micron. The large particle size range is calibrated to 2.5 microns and above. so the small number shows you .5 to 2.5 and the large is 2.5 and up.

A company representative informed me that it filters 100% of that particles. Their website says "99%" of particles. Another company representative said that it was "under 1 micron."

Sorry Scott, I can't. I only know there is no uniform calibrating of meters - and therefore they are all different. After trying 3 - I found, for me, the Freestyle Lite to be the most accurate. My daughter uses One Touch - and her readings come in high too.

Mine arrived with a calibration slide. (A metallized scale ) You can use the software to set a grid value with it, and get results as as good or better as an eyepiece micrometer.The software has to be mastered, and it can take a while.

No, you cannot. F/2.8 is only available for objects that are far enough. For the closest objects (0.38m) it will be F/5.6.

No this is not what your looking for. If you google infraded therometer you should be able to fond what your looking for. Good luck

no definitive #'s bottle just states "nano meter particle size and a a graph showing particle size is in the smallest angstrom size. Maybe ask manufacturer

Calibration is not possible to the best of my knowledge. I have found it to be accurate + or - 1 or 2 grams and I think that is more a sensitivity issue (placement, etc). Hope this helps. As noted above - "tare" is certainly possible if that is what you meant.

Using the software at the following website science4all.nl/?Microscopy_and_Photography___MICAM you can see certain microbes... would not say cells... the max resolution of 1280 pixels and calibrating 1/64" = 397 micrometers what I measure on screen I see less approximately 175x

according to bottle, particles range in size from .2 microns to 150 microns
