Rain gauge BRADAS WL-M17 White Line 9721 – capacity up to 160 mm/m², model for outdoor precipitation measurement

The BRADAS WL-M17 White Line 9721 mechanical rain gauge measures precipitation up to 160 mm/m² and is designed for outdoor placement. The instrument provides direct, easy-to-read analog measurements of accumulated rainfall and is suitable for monitoring precipitation in gardens, allotments, small farms, hobby weather stations and irrigation planning. The rain gauge is simple in construction, requires minimal maintenance and works without power supply, making it usable in remote or off-grid locations.

Advantages

The device offers straightforward mechanical operation with clear graduated markings for quick reading. Its compact, weather-resistant housing is built for outdoor exposure and resists typical environmental conditions. Installation is uncomplicated and the gauge does not require batteries or electronic components, reducing maintenance needs. The capacity up to 160 mm/m² allows tracking both light showers and heavy rainfall events with a single instrument.

Suitable for

• Garden and allotment precipitation monitoring
• Small-scale agricultural irrigation planning
• Hobby and home weather stations
• Outdoor environmental observation and data logging

Key specifications

• Measurement principle: mechanical, direct reading
• Maximum measurable precipitation: 160 mm/m²
• Mounting: outdoor installation on level surface or mounting post
• Power: none required (mechanical operation)
• Materials: weather-resistant plastics and corrosion-resistant components
• Display: graduated analog scale for accumulated rainfall readings

How to use

Place the rain gauge on a level, open site away from obstructions such as trees, buildings or overhangs to ensure accurate precipitation capture. Secure the unit according to the included mounting instructions so it remains vertical and stable during wind. After a rainfall event, read the accumulated precipitation value from the graduated scale at eye level and empty or reset the collection area if the model requires manual draining before the next measurement. Regularly inspect the funnel and collection chamber for debris and clean as needed to maintain measurement accuracy.

Usage recommendations

Check placement periodically to ensure the gauge remains level and free of blockages. For continuous monitoring, record readings at consistent intervals (for example, daily at the same time) to build a reliable precipitation log. Avoid placing the gauge near roof overhangs or dense foliage to minimize undercatch or splashing errors.
