Measurement notes
Short technical articles for teams that need inspection, laboratory, weighing, and calibration decisions to remain explainable after the first purchase conversation has passed.
Searching for “how to calibrate ph meter mettler toledo” seems harmless. In practice, it is a symptom of broken documentation ownership—and it costs labs thousands in time, mistakes, and failed audits.
By Marcus FeldWhy an Evident Scientific Microscope still needs acceptance criteria — and what microscope buyers can learn from queries like zeiss vs global dental microscope.
By Marcus FeldA QC supervisor shares what happened when false weight rejects and tamper evident band failures appeared on the same line—and why he bought a portable oscilloscope and IC thermal camera before the real culprit showed up under an Evident scientific microscope.
By Marcus FeldAn office administrator explains why delivery certainty and technical support matter more than the lowest quote when buying lab instruments—from a digital micrometer and non-contact voltage tester to an Evident microscope, Evident logo verification, and FLIR thermal camera training.
By Marcus FeldA quality manager explains what a $22,000 encoder rework taught her about measurement method, instrument settings, and why incoming inspection has to work as a feedback loop, not a one-time step.
By Marcus FeldWhich Fluke multimeter should I buy? I've made expensive instrument buying mistakes, so you don't have to. Here's a practical comparison: the No. 436 micrometer, digital alternatives, and why small shop orders deserve serious support.
By Marcus FeldA procurement manager answers common questions about Evident NDT equipment, Evident microscopes, the Fluke 325 true RMS clamp meter, thermal cameras, and where to buy Fluke multimeter products without hidden costs.
By Marcus FeldA quality manager's scenario-based guide to choosing lab and field instruments, including Evident/Olympus transitions, refrigerated centrifuges, Coriolis flowmeters, and the Klein vs Fluke multimeter debate.
By Marcus FeldStraight answers on Evident microscopes, iPhone thermal cameras, automotive oscilloscope use, and the Cognex/Sony sensor rumor. Written by someone who handles rush instrument orders.
By Marcus FeldAn experienced purchasing administrator shares practical guidance for buying lab equipment and measurement instruments, with different strategies for new setups, replacements, and budget-limited purchases.
By Marcus FeldSend the technical question, equipment context, and quality standard. Evident can route the topic to an engineer who understands both the instrument and the record.
