Soil density soil porosity volume tester tester sealing wax density measurement

Patent Number: ZL201320080171.0 three-year warranty effect: confirm the suitability of the soil for crop growth, if the soil is too dense, hindered development of plant roots, and ventilation, poor drainage, poor plant growth. Function: simple, fast read paraffin membrane available soil overall density, specific gravity bottle method available soil particulates density specification: ASTM D4254, D852, D854, SL-237 standard procedures: Step 1, put soil samples measuring station Press the M key on. Step 2, the closure of wax water treatment. Step 3, after sealing wax treatment on the measuring bench press M key. Step 4, turn on the water after sealing wax process, press the M key. The overall density direct read test model TWD-150J Type: solid, granules, films, the maximum floating body weighing: 150g Weighing accuracy: 0.001g precision density: 0.0001 g / cm3 display value: density, porosity, water absorption temperature, solution set of compensation: 19.999 solution compensation can be set online interface: RS-232 Advantages: 1, the body of aluminum alloy casting, structural stability. It does not exist because of keystrokes and the impact sensing element to detect, causing instability screen appears. 2, the body is integrally formed, because there is no solution overflow penetrate the circuit board and sensor damage caused problems. 3, the machine's sensors measure the position and the same platform, because there is no corner of the load factors, resulting Deviation measurements. 4, the screen mining elevated independent design and measurement station separation, the panel due to infiltration and adhesions solution, and there is no question of damage. 5, the equipment weight to volume expansion, solution expansion and air buoyancy compensation.
