Cole-Parmer Soil Sampling Gravelometer: Meets USGS Standards

Cole-Parmer Soil Sampling Gravelometer: Meets USGS Standards

• USGS STANDARDS COMPLIANCE: Meets United States Geological Survey standards for cobble size measurement
• 14 SQUARE HOLES: Features 14 square holes in common sieve sizes; 1/2 phi unit classes ranging from 2mm to 180mm
• BUILT-IN SCALE: Metric scale measures up to 310mm in 10mm increments along one side
• LIGHTWEIGHT CONSTRUCTION: Anodized aluminum construction; dimensions 13.5 inches by 11 inches (34.3cm by 27.9cm)
• FIELD USE: Designed for grading and measuring gravel and cobble-sized bed sediments in field applications

This device from wildco --also known as a gravel meter or pebble meter--is used to grade or measure gravel and cobble-sized bed sediments in the field. Your Cobble measurements will be far more accurate than using a ruler. Made of anodized Aluminum, it is lightweight yet strong, therefore easy to carry and use in the field. It incorporates 14 square holes of common sieve sizes (1/2 PHI unit classes) ranging from 2 mm to 180 mm. Measure up to 310 mm (in 10 mm increments) using the built-in scale. Dimensions: 13 1/2 inch x 11 inch (34.3 cm x 27.9 cm) meet usgs standards in Cobble size measurement 14 square holes in common sieve sizes lightweight construction for easy field use metric scale along one side
