Product description AC DC high voltage dividerFRC series AC DC high voltage divider also known as FRC Divider, it is a kind of resistance-capacitance equivalent potential screen voltage division type high voltage measurement device, is mainly used for the measurement of pulsed high voltage, lightning high voltage and power frequency high voltage. It is the first choice for the replacement of high voltage electrostatic voltmeter.
The Intelligent Tg dielectric loss tester is equipped with high voltage step-up transformer. Besides, it takes security measures like zero-cross closing, lightning protection, etc. During the experiment, different levels of high voltage ranging from 0.5KV to 10kV are outputted. The instrument has the advantages of convenient and safe operation.
Technical index
The Intelligent Tg dielectric loss tester has: printer, keyboard, indicator and communication transmission.
Detect internal standard capacitor current: 10�¼A~1A
Used to determine the permeability coefficient of the soil, The whole system is compact. Reasonable design, Convenient to disassemble and assemble, equable stress (use the hand wheel to do the rotary extrusion in the center). All accessories made of high quality cuprum except frame. There are two Position-limit flight of steps on the protective ring, during the process of pack stop-hydrosphere, not only assure the sample will not hang, but also protect cutting ring and control the deformation degree of rubber ring.
Constant Head Soil Permeameter is used to determine the penetration coefficient when the sand soil and the incoherence soil which has few broken-stones to carry on the permeability test under constant head.
Designed to provide reliable results from a unit which is compact without sacrificing accuracy and repeatability. It comes with triple beam ratio and compact design ensures space saving.
It is used in soil compression test to detect the relationship between soil pressure and deformation, calculate the unit deposition, compression index, resilience index and consolidation coefficient of soil, etc.
The stainless steel peat sampler is in fact a kind of gouge auger. The peat sampler is pushed into the soil manually. The sample containing part is a half cylinder. The peat sampler distinguishes itself from the standard gouge auger as its cone is massive.
The sample containing section is sealed off by a plate (fin) that can pivot around the axle in the middle of the sampler and that is fitted with a cutting edge on one side. Having arrived at the correct sampling depth the complete sampler is given half a turn clockwise (180). During the turning the fin remains in position which allows the half cylinder to be filled and closed again.
The half circular sample cylinder is kept closed by the other side of the fin during extraction.
Usage: Used for checking the compressive strength of lime soil.

Foundation Testing PIT Pile Integrity TesterThe dynamic testing instrument for foundation pile is a test and analysis instrument for testing the structural integrity of foundation pile and the vertical bearing capacity of single pile under impact or vibration load in the process of pile integrity testing and monitoring of prefabricated pile. The purpose is to determine the bearing capacity and structural integrity of pile.
This tester is used to test the bonding strength of decorative bricks, tiles, mosaics, various plates, paints, coatings, exterior wall insulation materials (EPS panels, SPS panels) and also be used to test the bonding strength of various exterior wall building materials and adhesives.
The purpose of the test instrument is to calculate the maximum and minimum of cohesive soil porosity, and used to calculate the relative density, to understand the soil in the state of nature or the elastic after compaction and the stability of soil grain structure.
