  • This is how electrical conductivity and pH are connected

    Although these concepts have different definitions and methods of measurement, they are closely connected in ways that reveal important information about the chemical composition and behavior of solutions.

  • New standalone thermal camera starts instantly, targets hidden faults

    Rision’s new fully self-contained device is designed for industrial inspectors, HVAC works and more.

  • New 10-minute paper test spots 'devil's breath' in drinks

    The team explained that scopolamine poses a significant public health and forensic concern because its effects can leave victims vulnerable, while its lack of color, odor and taste allows it to go undetected when ingested.

  • Could body odor reveal disease? New laser approach offers clues

    The technique builds on the observation that certain diseases can change the VOC composition of exhaled breath and bodily fluids, producing distinctive chemical signatures within the human volatilome.

  • Emerson's new four-port VNA expands RF testing

    The testing tool supports MIMO testing and multiport S-parameter applications.

  • Why, how and when to measure conductivity, total dissolved solids and salinity

    Since all three are related to the presence of dissolved ions, they can sometimes seem interchangeable. However, each parameter provides a different perspective on the sample.

  • How to select a reliable high-power DC power supply

    A reliable power supply can not only deliver stable voltage and current but also simulate complex operating conditions and protect costly devices under test (DUTs).

  • Understanding pH sensor diagnostics

    This article will then expand on this to demonstrate how pH sensors can become damaged, how this may impact measurements and what you can look out for to correctly diagnose the issue.

  • New detector seeks out nuclear material hiding in air ducts

    The ORNL team developed the new monitor, which was designed to check every minute or every second for the accumulation of nuclear material in the air ducts.

  • When should you replace your pH sensor?

    It depends largely on its usage.

  • New monitoring framework exposes hidden weaknesses in urban metro corridors

    The result is what the team calls a forensic multi-scale remote sensing (MSRS) framework that blends InSAR, laser scanning (L/S) and ground penetrating radar (GPR) capable of detecting possible infrastructure problems.

  • Why cleanroom environmental control necessitates an expert approach

    Advanced HVAC systems help compounding pharmacies maintain cleanroom conditions, ensuring contamination control, regulatory compliance and precise environmental management.

  • Exhaled breath sensor could detect SARS-CoV-2 in minutes

    Operating much like a breathalyzer, the new noninvasive test offers results almost immediately.

  • Two-point versus three-point calibration: Choosing the best method for accurate pH measurement

    While two-point calibration offers a quicker and simpler solution for routine checks, three-point calibration provides a more comprehensive adjustment that can account for electrode non-linearity and drift over a wider pH range.

  • New portable laser system from China targets drones

    The new system focuses a laser beam on a distant target, such as a drone. That beam burns through wires, destroys sensors and cameras, or overheats battery packs, thus destroying the drone.

  • The most common errors in pH measurements and how to avoid them

    Explore the most common errors encountered in pH measurements, understand why they happen and discuss best practices to minimize these errors for more reliable results.

  • Understanding pH slope

    The pH slope is like the heartbeat of your sensor — a fundamental indicator of electrode health and measurement reliability during calibration.

  • UK to advance hydrogen for industrial heating

    A real-world, industrial-scale testbed will help manufacturers trial hydrogen fuel-switching in a controlled environment.

  • New light-controlled microgripper delivers both accuracy and force

    By combining the precision of light-based tools with the gripping strength of mechanical devices, the gripper promises to improve the ease with which researchers can manipulate and assemble objects at the microscale.

  • New diagnostic brush test delivers oral cancer results in one hour

    The test was designed with the promise of revolutionizing oral cancer detection and preventing roughly 90% of unnecessary harmful scalpel biopsy procedures.
