safety, driven by dedication, and delivering innovation.
Many industrial facilities already have leak detectors installed. However, in real operating environments, water-related false alarms, frequent sensor failures, high maintenance costs, and limited detection of organic solvents and oils continue to reduce alarm reliability. Yoohantech improves site safety with leak detection technology optimized by chemical family that does not react to water and focuses on actual chemical leaks.

When we visit chemical plants, logistics warehouses, semiconductor fabs, battery plants, and wastewater treatment facilities, we often hear the same concerns.
“The leak detector is installed, but alarms go off so often that we barely use it.”
“It alarms during rain or even during floor cleaning.”
“Sensor replacement is too expensive, so the system is often left unattended.”
“We thought organic solvents or oils were difficult to detect.”
The issue is not simply the absence of leak detectors. Many systems are installed but cannot be fully trusted during an actual leak event. When false alarms repeat, operators become desensitized, and response may be delayed when a real chemical leak occurs.

Film Sensor False Alarm with Water

False Alarm Risk During Floor Cleaning

Optical Sensor Reaction to Water
Many film-type or optical leak detectors used in industrial sites cannot distinguish water from chemicals. As a result, alarms may occur during floor cleaning, seasonal condensation, wash water inflow, rainwater exposure, and equipment washing operations.
At first, every alarm gets attention. But repeated false alarms dull the site’s response. Eventually, operators may think, “It is just another false alarm.” This can cause a real chemical leak to be missed.

Film-type leak sensors are often installed directly on the floor. But industrial sites are much harsher than they look, and the floor is a difficult environment for sensors.
Repeated forklift traffic, foot traffic, chemical exposure, moisture, dust, and washing can lead to sensor damage and cable disconnection. Eventually, the entire sensor must be replaced, and material cost, labor cost, and production downtime can all become additional expenses.
Site engineers often ask, “Isn’t it difficult to detect organic solvent leaks?” However, this misconception often comes from not having experienced a sensor designed for organic solvent detection.
Organic solvents and oils used in industrial sites, such as IPA, ethanol, acetone, toluene, xylene, NMP, lubricating oil, cutting oil, diesel, and insulating oil, organic solvents and oilscan create fire and explosion risks when leaked. Early detection is therefore critical.

Intrinsically Safe Leak Detector

Field Installation at Industrial Sites

On-site Leak Detection Test
Yoohantech leak detectors are not designed to react to every liquid. They use leak detection technology optimized by chemical family, tailored to the chemical family and characteristics used at each site.
Sensor for Acids, Alkalis, and Inorganic Solutions
Detects acid, alkali, and inorganic solution leaks while remaining non-responsive to water.
Sensor for Organic Solvents and Oils
Improves detection reliability for organic solvent and oil leaks.
Unlike conventional film-type sensors, there is no need to replace a large detection area as a whole. Depending on the sensor structure, cartridge replacement or wash-and-reuse maintenance can be applied to reduce maintenance costs.
The purpose of a leak detector is not simply to complete an installation requirement. What really matters is whether it detects accurately when a leak actually occurs.
A system that operators ignore because of repeated false alarms is no longer a true safety system. It is time to review water-related false alarms, frequent sensor replacement, high maintenance costs, and organic solvent detection limitations.
If you need a leak detection system for chemicals, organic solvents, oils, acids, or alkalis, contact Yoohantech. We recommend the right leak detection solution based on your site conditions and target liquid characteristics.
