Product Number: 0325KL1 HAND PENETROMETER KIT, 1 Meter, Mechanical Gauge type Penetrometers are used to determine the resistance to penetration (bearing capacity) of a soil. A good reliable penetrometer can provide a wealth of information on the stability of a wilderness road to the compaction of agricultural fields subjected heavy equipment use over a season. In either case one needs to know with specific data how and in what manner changes are taking place over time and with differing weather or application effects. This hand penetrometer provide an cost effective tool that’s easy to carry to the field and has all the accessories together to make almost any measurement required. This easy set can be used for fast and reliable probing to a dept of 1 meter. The set comprises: Various cones Probing- and extension rods Measuring instrument with a pressure gauge Tool set Cone check Calibration certificate, instruction manual and carrying case Measuring range 10,000 kN/m 2 (=10,000 kPa) Accuracy +/– 8% FS

	Product Number: 0326K1 New Penetrologger with GPS and soilmoisture sensor The carrying capacity of the soil is simple to measure with the penetrologger. The penetrologger measures the resistance of the soil or the shallow subsurface and is a suitable instrument for use in civil engineering, soil science, agriculture, sports field maintenance and park and public garden management. For civil engineering purposes a high degree of resistance is generally desirable. This concerns the ability to determine the suitability for foundations for buildings and infrastructure projects. Conversely, for agricultural purposes an excessively high resistance can present problems. A high degree of compaction can impede root development and the oxygen supply to the roots. When the resistance is too low this can mean too little carrying capacity for cattle to walk round or for agricultural machinery to operate.  Unified Soil Classification System  The so-called Unified Soil Classification System (USCS) determines whether a vehicle carrying a load is able to drive across a certain piece of land. The classification is expressed in figures, one for the vehicle and one for the soil. The figure for the vehicle, the Vehicle Cone Index ( VCI ), has no dimension and is based on various factors, e.g. soil accessibility, soil pressure and the ratio between engine capacity and weight of the vehicle. The Cone Index (CI) represents the soil figure. This figure can be determined by means of a cone-penetrometer. A comparison of both indexes shows the suitability of the terrain for driving over.  The penetrologger consists of:  the penetrologger with force sensor, a bi-partite probing rod, a cone, the depth reference plate, a communication port and a GPS antenna. The cone is screwed on the probing rod, which is connected with a quick coupling to the force sensor on the penetrologger. Now the cone is pushed slowly and regularly into the soil. The depth reference plate, which is on the soil surface, reflects the signals of the ultrasonic sensor, which results in a very accurate depth measurement. The measured resistance to penetration and the GPS coordinates are stored in the internal logger of the penetrologger. Optional is the possibility of soil moisture measurement with an external soil moisture sensor (1 measurement per penetration).  Characteristics new penetrologger: • Display of Vehicle Cone Index • Precise internal GPS -system • Optional soil moisture measurement • Larger storage capacity • Inclusion of French and Spanish language functions • Simplified operation • New PC software • New robust design  Technical specifications: • Operating temperature 0 - 50 °C • Operating humidity IP 54 (splash water proof) • Penetrologger weight 3.4 kg (7.5 lbs) (excl. rod, incl. battery) • Overall carrying/shipping weight 15.5 kg (34 lbs) • Dimensions for transport 58x29x25 cm (23x12x10 inch) • Memory 1500 measurements • Maximum penetration force 1000 N • Force resolution 1 N • Depth registration 80 cm • Depth resolution 1 cm • GPS accuracy < 2.5 CEP (Circular Error Probable) • Soil moisture resolution 1%
