Many people refer to the pungent, acrid odor that emerges when opening a new cabinet as the "smell of new wood," assuming it will simply dissipate after a few days. In reality, however, what is being released could well be formaldehyde—a substance originating from the adhesives used in the pressed-wood panels—and our sense of smell is not a reliable enough gauge to determine the concentration levels present
Regulation QCVN 07:2025/BNNMT (replacing QCVN 07:2009/BTNMT and QCVN 50:2013/BTNMT) specifies hazardous waste and sludge thresholds based on leachate concentrations. To ensure that analytical results for heavy metals and organic compounds are accepted during ISO/IEC 17025 or VIMCERTS assessments, laboratories must comply with the Toxicity Characteristic Leaching Procedure (TCLP) specified in TCVN 9239:2012, which is equivalent to US EPA Method 1311
An infrared thermometer allows surface temperature measurement without direct contact, making it suitable for products coming out of curing ovens or surfaces that are difficult to access. However, to ensure reliable results for production quality control, it is important to understand the measurement principle and the factors that affect measurements on painted and coated surfaces.
Thermal imaging supports data center maintenance by making temperature irregularities visible in electrical and mechanical equipment. Repeatable inspections can document temperature trends and inform timely repairs.
A thermal imager may detect a heat source at one pixel, but temperature assessment and object recognition require greater pixel coverage. D:S ratio helps determine whether a target can meet that requirement at a given distance.
Discrepancies when measuring the surface temperature of metals using an infrared thermometer primarily stem from low emissivity, reflected radiation from the environment, and unsuitable measurement conditions.
For PCB research, thermal imaging can capture temperature information across an entire board without contact. FOTRIC 600 R&D is described with up to 307,200 temperature points per image, radiometric video up to 30 Hz, and AnalyzIR software for pixel-level analysis.
Thermal imaging provides a non-contact way to inspect the thermal condition of petrochemical valves and flanges, helping identify anomalies associated with loose connections, faulty valves, and missing pipeline insulation.
An infrared thermometer is a useful tool for quickly checking the surface temperature of lithium batteries without direct contact. This method allows technicians to identify abnormal temperature areas, assess operating conditions, and inspect battery systems during maintenance.
You are measuring an amplifier, and only one peak appears on the screen—even though there are clearly two carriers. Or, you know for a fact that harmonics are present, but the noise floor sits above them. Or, after making adjustments, the scanner slows down to the point where you find yourself waiting for each individual sweep. These three scenarios often share a common cause: the RBW (Resolution Bandwidth)
