Abstract
A density measuring instrument, a water slot is arranged in the lower part and is upwards connected with a static support, an electronic balance is arranged on the top end of the static support; a dry weight weighing tray on the electronic balance is downwards connected with a movable support, two lower ends of the movable support are respectively connected with connection hanging wires, four lower ends of the hanging wires are connected with quadrangle ends of a wet weight weighing tray; the wet weight weighing tray is suspended and mounted in the water slot, liquid is provided in the water slot, the whole wet weight weighing tray is immerged in liquid of the water slot. The density measuring instrument has simple structure, convenient and fast test, accurate detecting result and no damage to the sample, is suitable for detections of noble metal and jewelry.
Description
Technical field
The utility model belongs to physical measuring instrument, particularly a kind of penetron.
Background technology
The density measure of object is cumbersome, need record the quality of testee, also will measure the volume of testee, and quality is obtained density divided by volume.But the bad measurement of the volume of general irregular object is determined, uses the graduated cylinder immersion to measure very inaccurate.Especially the jewellery of smallclothes precious metal, the strange shape of pattern, each can't determine actual volume.Therefore measure the jewellery density of heavy metal, determine that composition is very difficult.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of penetron is provided.Simple and easy to do just measurements and calculations exactly just draw the density of tested noble metal.
The technical solution of the utility model is:
A kind of penetron is characterized in that: there is a tank below, and tank upwards connects a quiet support, and an electronic balance is put on the top of quiet support; Dry weight weighing pan on the electronic balance connects moving support downwards, and each connects hang spring two lower ends of moving support, and two hang spring lower ends connect the two ends of weight in wet base weighing pan respectively; The weight in wet base weighing pan is unsettled to be contained in the tank, and tank has liquid, and weight in wet base weighing pan integral body is immersed in the liquid of tank.
The liquid of its tank is that the distilled water that phenixin is arranged is dripped on distilled water or surface.
The utility model effect is:
This penetron is simple in structure, and convenient test, quick is not damaged sample, and testing result is accurate, is applicable to the detection of precious metal and jewellery.

Embodiment
Wherein penetron is as shown in Figure 1: there is a tank 7 below, and tank upwards connects a quiet support 4, and an electronic balance 2 is put on the top of quiet support; The moving support 3 of dry weight weighing pan 1 connection downwards on the electronic balance, each 5, four hang spring lower end of connection hang spring, two lower ends of moving support connect four jiaos of weight in wet base weighing pan 6 respectively; Outstanding 6 skies of weight in wet base weighing pan are contained in the tank 7, and tank 7 has liquid 8, and weight in wet base weighing pan integral body is immersed in the liquid of tank.
The liquid of its tank is that the distilled water that phenixin is arranged is dripped on distilled water or surface.
Sample is put in 1, recorded sample dry weight quality, place and measure the weight in wet base quality in 6, the real density of sample is
M: dry weight m ': weight in wet base ρ wherein
x: sample real density ρ
Liquid: liquid is close in the test condition lower flume
ρ
Gas: atmospheric density under the measuring condition.
Penetron
This instrument is made up of electronic balance and sectional shelf-unit two large divisions.The range of electronic balance is 0.01g for the 200g precision.Sectional shelf-unit is made up of moving support, quiet support, hang spring, weight in wet base weighing pan, tank.Moving support and weight in wet base weighing pan material are aluminium alloy, and quiet support material is engineering plastics, and hang spring is a copper wire.Instrument integral body is canescence, high 330mm, and long 200mm, wide 210mm, the weight when tank is anhydrous is 3Kg.
Want earlier past tank water filling during operation, the water surface will be higher than weight in wet base weighing pan 10-20mm.Then with the electronic balance zero clearing.Earlier sample is placed on and measures dry weight on the dry weight weighing pan and note, and then put into tank, notice that at this moment sample will be immersed in the water fully, after charged sub-balance is stable, the record reading.In the reading input density measuring instrument software of dry weight and weight in wet base, can obtain a result.
Claims (3)
1, a kind of penetron is characterized in that: its penetron is: there is a tank below, and tank upwards connects a quiet support, and an electronic balance is put on the top of quiet support; Dry weight weighing pan on the electronic balance connects downwards moving support, and each connects hang spring two lower ends of moving support, and four hang spring lower ends connect four jiaos of weight in wet base weighing pan respectively; The weight in wet base weighing pan is unsettled to be contained in the tank, and tank has liquid, and weight in wet base weighing pan integral body is immersed in the liquid of tank.
2, penetron according to claim 1 is characterized in that: the liquid of tank is distilled water.
3, penetron according to claim 1 is characterized in that: the liquid surface of tank drips the distilled water that phenixin is arranged.
