Sol Solution PANDA - Lightweight Dynamic Cone Penetrometer With Variable Energy

The PANDA® is composed of:

• A striking head, equipped with a sensor to measure the energy at each impact
• A central acquisition unit, equipped with a sensor to measure the depression
• A dialogue terminal recording all the data, equipped with a GPS for the geolocation of the surveys and a screen for an instantaneous reading of the data
• A calibrated driving hammer

Data acquisition is automatic. At each beating are calculated

• Threshing energy
• The sinking depth
• Soil resistance

The operator can adapt his threshing energy according to the resistance of the ground encountered.

The obtained penetrograms are compared with reference lines established according to the class of the tested material and the required compaction quality. Any anomalies are automatically calculated in accordance with the NF P 94-105 standard.

The reference lines and the calculation of anomalies are available on the PANDA® acquisition box, allowing an assessment directly on site, and also on the online application Websprint©.

Soil classifications available:

• – GTR (France)
• USCS (Australia, Japan, etc.)
• AASHTO (USA)
• DIN 1896 (Germany)
• PG3 (Spain)
• Series 800 (UK)
• Qualiroute

Available compaction grades:

• Q2/Q3/Q4/Q5 (France)
• % OPN or % OPM (other countries)

Type of anomaly calculation:

• On the total height (NF P 94-105)
• By layer of constant densification (COFRAC),
• By backfill or coating zone (Fascicule 70-1)

The PANDA® is the most sold dynamic cone penetrometer in compaction control.
