Environmental Monitoring

The phenomenon of microalgal blooms in surface water sources, aquaculture ponds, and industrial water supply systems is becoming a major challenge for operations and environmental control

Wastewater treatment plants use aerobic tanks to break down pollutants. Biological problems occur when the sludge turns black with surface foam, causing effluent water parameters to exceed permissible limits. Addressing this situation requires engineers to measure core environmental parameters instead of adding random probiotics

Ultrasonic measurement helps determine the remaining thickness of acrylic windows from one side, supporting wear monitoring and aircraft window refurbishment. An ultrasonic thickness gauge enables inspection without removing the window or requiring mechanical measurement from both sides. Measurements can be performed from one side of the surface when the probe is properly coupled to the material.

A terminal lug inside an electrical cabinet may gradually heat up—a change almost imperceptible to the naked eye. A motor bearing begins to rise in temperature even before any abnormal noise occurs. These changes often manifest quite early, yet maintenance teams typically only begin investigating the cause once the equipment shuts down or a circuit breaker trips

An air pressure meter provides reference data for calculation models involving altitude, airflow, air density, gas volume, and measurement uncertainty. Any variation in atmospheric pressure can propagate errors throughout an entire measurement or control system

Two barometers placed side by side can display different atmospheric pressure readings. Learn the technical reasons behind these differences and what they mean for measurement accuracy.

A barometric pressure meter (barometer) often detects changes in weather conditions before rainfall begins. As atmospheric pressure falls, the structure of the surrounding air mass is also changing. However, there is no fixed pressure threshold that guarantees rain will occur.

Hanoi's air quality has shown signs of improvement following the introduction of E10 gasoline. What do the monitoring data indicate, and which indicators should be tracked to ensure an objective assessment?

What is the ideal TDS level for a shrimp tank? Many people spend a lot of time monitoring pH, temperature, and filtration systems but overlook TDS. Only when shrimp grow slowly, their colors fade, they have difficulty molting, or die off sporadically do they start checking their water source and discover that this indicator has long been out of the right range

TDS meters can operate reliably for many years, but the electrodes are the most subject to wear and tear. Each time a measurement is taken, the sensor surface comes into direct contact with water, dissolved minerals, and various other chemical components. This continuous process means the electrode's responsiveness gradually decreases over time.
