The "Leak Detector II AAM-PWLEAK02" is an ultrasonic detector equipped with a parabolic microphone that sensitively captures ultrasonic waves generated by gas leaks from piping, damage to rotating machine bearings, or circulation failures. It can identify leak points and detect bearing abnormalities. Abnormalities such as damage to bearings or inadequate lubrication manifest not only as vibrations or temperature changes but also accompany the generation of ultrasonic waves. Additionally, it is known that ultrasonic waves are generated by solid friction, such as belt slippage in belt-driven equipment. The "Leak Detector II AAM-PWLEAK02" detects these ultrasonic waves and notifies users through a bar graph and numerical display on the LED panel, as well as simulated sounds from headphones. It is effective for detecting air leaks from piping and gas leaks from various equipment, making it a useful tool for energy-saving measures, environmental conservation, and safety strategies across a wide range of fields.

The "SCOUT320Pro" is a thermal night vision scope that detects heat and does not miss targets even in complete darkness. Unlike traditional night vision that relies on light, this scope is equipped with a module that detects and visualizes heat. Any substance with a temperature above absolute zero (minus 273.15 degrees Celsius) emits thermal energy (infrared radiation). The thermal night vision scope detects and visualizes this thermal energy (infrared radiation) that is not visible to the naked eye. Because it detects thermal energy, it can penetrate smoke, fog, and foliage, allowing it to accurately capture targets even in adverse conditions such as backlighting, and it requires no light, making it usable in complete darkness. Additionally, its unique image processing algorithm, the DDE function, achieves high contrast and clear imaging. For more details, please contact us or download the catalog.

The warning water level detection device "AKI-1805" integrates a heater-equipped comb-shaped electrode sensor to improve malfunction caused by humidity and condensation, along with a drive circuit that determines the presence of rain based on the resistance value between the comb-shaped electrodes. Since the sensor and drive unit are integrated, there is no need to create surrounding circuits, making it easy to handle. The sensor is heated by the heater, which improves malfunction caused by humidity and condensation. After being immersed in 1% seawater, the humidity test results (with the sensor surface in a dirty state) show normal operation at 90% humidity, with characteristics improved by 10% compared to without the heater (manufacturer comparison), and the built-in heater accelerates the drying of the sensor surface. Due to low voltage and AC drive, corrosion from electrolysis of the comb-shaped electrodes (sensor) can be suppressed. For more details, please contact us or download the catalog.

If the infrared light reception drops below a certain level due to bad weather, it will notify the receiving unit of the environmental deterioration. The malfunction prevention circuit, which mitigates the effects of heat haze, atmospheric fluctuations, temperature changes, and lighting, ensures safe operation with a full safety system. With a powerful beam essential for outdoor security, it maintains a detection range more than ten times greater than the actual warning distance to accommodate attenuation from stray light, rain, snow, fog, and other adverse weather conditions. The built-in aiming device and the included sensitivity checker make optical axis adjustment simple and reliable.
