3. Usage Features
4. Maintenance Features

The ALD-40 Carbon Dioxide Gas Leak Detector is a hand-held device utilizing the infrared spectrum absorption principle for detecting CO2 gas leaks. Compared to traditional leak detectors, it offers a longer sensor life, higher detection accuracy, and a wider range of carbon dioxide detection. The device is equipped with a large LCD screen for intuitive display of test results and features an ergonomic design for user comfort.

Function Description:

The ALD-40 detects carbon dioxide gas leaks by slowly moving its probe (approximately 3 inches per second) at a distance of 0.25 inches near a suspected leak area. When a leak is detected, the screen displays the intensity of the leak, and an audible tone changes to a siren sound. The device is designed to be user-friendly with clear operational controls.

Important Technical Specifications:

• Sensor Principle: Infrared spectrum absorption
• Sensor Life: 10 years
• Sensitivity: 400ppm (ranging from 400ppm to 4000ppm) /year
• Alarm Mode: Sound and light alarm, LCD display
• Battery: Built-in rechargeable lithium battery 3.7V 3000mAh
• Working Time: Continuous 6 hours
• Charging Time: 4 hours
• Operating Environment: -10°C to 52°C (14°F to 125.6°F) / Relative humidity (20% to 85% RH)
• Storage Temperature: -20°C to 60°C (-4°F to 140°F)
• Weight: 415g (14.6oz)
• Size: 201mm x 86mm x 38mm (7.9" x 3.3" x 1.5")
• Certification: CE certification

Usage Features:

The ALD-40 offers several key operational features for ease of use:

• ON/OFF Key: Press the button for 2 seconds to power the device on or off.
• RSET Key: Long press the button for 3 seconds to reset the sensitivity benchmark. This is useful for establishing a new baseline for detection.
• PEAK Key: Press the button to record the maximum value of leakage detected during a test.
• SENS Key: Press the button to adjust sensitivity levels. The default sensitivity is set to medium.
• MUTE Key: Press the button to turn the buzzer sound on or off.
• Setup: Before testing, ensure the device has sufficient battery level. Turn on the device using the ON/OFF button and wait for 30 seconds for it to warm up and stabilize. The sensitivity can be adjusted using the SENS button.

Maintenance Features:

To ensure the longevity and proper functioning of the ALD-40, several maintenance guidelines should be followed:

• Environmental Protection: Do not submerge the product in water or allow water to enter the intake of the probe. Avoid exposing the product to temperatures exceeding 60°C (140°F) or leaving it in direct sunlight for long periods.
• Device Integrity: Do not dismantle or attempt repairs without authorization. The included lithium battery should not be changed or replaced.
• Battery Care: Do not leave the device uncharged for more than 6 months to prevent battery damage. Use only the supplied charging cable.
• Operational Safety: Do not use the device on objects with an electrical charge or appliances connected to a power source. Ensure the filter is present and clean before performing a test.
• Health and Safety: Avoid inhaling refrigerant vapor, as high concentrations are harmful and can lead to coma or death.
• Technical Support: In case of any technical problems, users are advised to contact the provided support channels.
