Wastewater treatment plants serving apartment complexes, buildings, and residential areas sometimes experience effluent COD levels approaching regulatory limits, particularly following sudden load surges or shortly before scheduled compliance sampling. QCVN 14:2025/BTNMT, applicable to domestic wastewater from September 1, 2025, sets COD limits based on discharge volume and the receiving water body, while allowing dischargers to choose between TOC and COD parameters

The global energy transition trend is driving industrial plants, chemical facilities, and renewable energy sites to integrate hydrogen as a strategic fuel source to achieve decarbonization goals. However, practical experience shows that traditional mechanical pressure gauges rapidly degrade in service life and experience dangerous failures when in direct contact with hydrogen environments.

In semiconductor cleanrooms, a single microscopic dust particle or a tiny toxic gas leak is enough to ruin an entire wafer batch worth millions of dollars. This vital requirement is accelerating a complete transition from traditional mechanical pressure gauges to digital pressure sensors and electronic pressure gauges.

The Bosch GLM laser distance meter series has long been a staple on construction sites and in manufacturing workshops. Mastering these hidden features optimizes construction schedules and significantly reduces manual operational errors.

A 2-port probe can measure PCB power-rail impedance with minimal board changes. For the VDD_3V3_S0 example, ON-state impedance was checked against an approximately 8 mΩ target through 7 kHz.

The 2-port shunt-through technique is used for milliohm impedance measurements at very high frequencies. Ground loops from instrument grounds and test cabling can introduce major error; the Picotest J2102A is used as a ground-loop breaker for measurements down to 20 micro-ohms.

Power-hungry AI accelerators and other high-performance chips increase the relevance of power integrity testing. Key topics include voltage regulator modules, PDN impedance measurement, and reducing the effect of probe ground-loop resistance with a low-noise isolator.

Choosing the right laser distance meter for your industry helps optimize work efficiency, reduce costs, and ensure measurement accuracy.

Laser distance meters typically achieve millimeter-level accuracy indoors, but errors immediately appear when used on a blazing construction site. The root of the issue lies deep within the physical and optical mechanisms operating inside the device

Directive (EU) 2024/1799 of the European Union (adopted on June 13, 2024, and officially taking effect on July 31, 2026) is the "Right to Repair" Directive, aimed at promoting the repair of goods rather than their disposal.
