The caliper or "pinch an inch" can be fairly reasonable if the tester administered the test correctly. They might not have placed it in the right spot or could have even not separated the muscle from the fat , which would give false readings.
A caliper is more accurate.
A vernier caliper.
The micrometer caliper is generally more accurate in measuring the density of an object compared to the vernier caliper. This is because the micrometer caliper has a higher precision and can measure with greater accuracy, typically up to 0.01mm.
Some are accurate.
A Vernier caliper is quite accurate and idiot proof. Part of its accuracy lies in its general ease of use.
caliper to 5 per cent millimeters and micrometer to 1 millimeter per cent.
I believe they are fairly accurate, but probably not 99.9%. I've gotten false positives on urine tests before, but they're usually pretty accurate.
yes
A vernier caliper would be a good way, unless you need a more accurate measurement, in which case I might use a micrometer caliper.
are the pregant tests tubes accurate?
A vernier caliper uses a sliding scale with a main scale and a vernier scale to measure length, while a digital caliper uses electronic sensors to provide a digital readout. Digital calipers are generally more accurate for precise measurements due to their digital display and ability to provide measurements in decimal form.
The caliper and micrometer use a dial or digital readout to measure the distance between the tips. The tolerances of these tools can be under .001 inch, making them extremely accurate.
