Why does Guizhou Qianhong Engineering Quality Inspection Laboratory recognize QJ36B-2 digital bridge and other equipment
Guizhou Qianhong Engineering Quality Inspection Co., Ltd. was established in May 2010, with a testing business office building covering an area of 5300 square meters. The internal departments include the External Inspection Department, Internal Inspection Department, Comprehensive Department, Finance Department, Quality Control Department, Business Department, Gui'an Company, Huishui Testing Room, and Pingtang Testing Room. There are currently 60 testing and management personnel, including 1 registered structural and geotechnical engineer, 3 engineers, 8 engineers, and 48 inspection and testing personnel. More than 300 sets of instruments and equipment.
The qualification has been approved by the Department of Housing and Urban Rural Development of Guizhou Province and the Quality and Technical Supervision Administration of Qiannan Prefecture. The scope of detection capability includes: municipal road engineering; Urban rail transit engineering; Ground foundation engineering inspection; On site inspection of the main structural engineering; Steel structure engineering inspection; Indoor environmental quality testing; Witness sampling quality testing; Energy saving insulation materials; Identification of building structures; Testing of geosynthetics, waterproofing materials, pipes and fittings, and rubber bearings; Adhering to the principle of "testing according to standards, speaking with data", we provide society with data and results that serve as evidence, provide inspection and testing reports, and give back to customers with high-quality services.
Under such high quality inspection requirements, Guizhou Qianhong Engineering Quality Inspection Co., Ltd. has purchased the Keitel Digital DC Double arm Bridge QJ36B-2 and Conductor Bridge Fixture, as well as three measuring devices for measuring projector K-GFT301. These three devices have been on the market for nearly 9 years with almost zero complaint rates.
The main features of QJ36B digital DC double arm bridge are:
1. Adopting a 5-digit LCD display, it is easy to operate, intuitive to read, has high measurement accuracy, and good stability.
2. No need for accessories such as galvanometer, power supply, standard resistor, etc., easy to carry.
3. With temperature compensation: Based on the temperature measured by the thermometer, the bridge automatically converts it into a standard resistance value of 20 ℃.
4. The user needs to be able to measure a resistivity of 1 meter.
5. The bridge adopts a plastic chassis, which is aesthetically pleasing and easy to carry.
6. Measurement range: 0-2K Ω
7. Small resolution: 0.01u Ω
8. Accuracy: 0.05%
The main features of KTR005B new conductor bridge fixture are:
A device specifically designed for testing the resistance of bare round copper wire, aluminum wire, and multi stranded wire to meet the requirements of the newly revised GB/T3048 standard for conductor resistance testing. In order to better meet the requirements of the standard regulations, and based on the principle of speed and convenience, this fixture adopts forward and backward threads to improve the loading and unloading speed. At the same time, due to the use of a double slot aluminum alloy bottom plate, the structure is more reasonable and the use is more convenient. Scope of use: Used in conjunction with QJ19, QJ36, QJ36S, QJ36B, QJ44, QJ57 and other electric bridges to detect the resistance per meter of wires.
The main features of K-GFT301 measurement projector are: it belongs to precision measurement projector and is widely used in hardware, stamping, precision plastics, terminals, molds, screws, cutting tools, etc. Capable of detecting the contour dimensions and surface dimensions of various complex shaped workpieces. The optical system of the instrument has excellent quality, with clear objective imaging and accurate magnification. Under transmissive illumination, the contour measurement error is less than 0.08%; The coordinate measurement indication error can reach (3+L/75) μ m, where L is the measured length in millimeters; This projector can withstand heavy loads on precision components without affecting accuracy.
X coordinate stroke 150 (mm), Y coordinate stroke 50 (mm), Z coordinate stroke 70 (mm for focusing), X and Y coordinate digital display resolution: 0.001, projection screen size (mm): Φ 312, applicable range>Φ 300 (engraved with meter lines), projection rotation range: 0-360, rotation angle digital display resolution: 1 'or 0.01
Thank you very much to Guizhou Qianhong Engineering Quality Inspection Co., Ltd. Laboratory for their generous support of three testing equipment, including the Keitel QJ36B-2 digital bridge!
