Supported Applications
The Omega LDH-380 Refrigerant Leak Detector is a handheld device designed for detecting refrigerant leaks in air-conditioning and cooling systems. The unit utilizes a semiconductor gas sensor with microprocessor control and digital signal processing to identify the presence of specific gases.
- Air-conditioning systems
- Cooling systems
The detector is compatible with R-22, R-134a, R-404A, R-407C, and R-410A refrigerants. The product overview notes that the unit measures Freon gas.
Operating Conditions & Performance
The LDH-380 operates within an ambient temperature range of 0 ~ 40 °C. Storage conditions are specified as -10 ~ 60 °C. Humidity limits for operation and storage are defined in the documentation.
- Operating humidity: < 80% RH
- Storage humidity: < 70% RH
Sensitivity specifications vary by refrigerant type, with High (H) and Low (L) settings available:
- R-22, R-134a: H setting detects 6g/year; L setting detects 30g/year.
- R-404A, R-407C, R-410A: H setting detects 8g/year; L setting detects 40g/year.
The device features a tricolor LED bar indicator and an audible buzzer for output signals. A high/low sensitivity selector allows the user to adjust detection thresholds based on the specific refrigerant being tested.
Configuration Options
The LDH-380 series is configured as a handheld unit with integrated power and sensing components. The probe assembly includes a flexible stainless steel sheath designed for leak inspection in various system geometries.
- Power Supply: 4 AA size (6V DC) Alkaline Batteries
- Probe Dimensions: Overall length of 40cm (15.5") with a stainless steel sheath material.
- Housing and Weight: Overall dimensions are 173 x 66 x 56 mm; weight is approximately 400g.
The standard package includes the leak detector unit, four alkaline batteries (AA), a user manual, a leak check bottle for reference testing, and a carry case. The device carries CE approval and references ISO 9001 and ISO 9002 certifications in its documentation.
Key Product Differences
The LDH-380 is offered as a single model configuration within this series bundle, identified by the part number LDH-380. The device includes fixed features such as the tricolor LED bar indicator and buzzer output; no alternative display or communication options are documented in the provided source.
Important usage constraints noted in the documentation include:
- The unit is not equipped with anti-explosive designs and measures; it should not be used in environments containing burnable gases.
- Avoid use in pollutant places, areas with large temperature variation, high wind velocity, organic solvents, adhesive vapor, fuel gas, or vesicants.
- Do not use the unit where too much Freon gas is present.
