SHJ-40 Concrete Strength TesterDetailed product description：

SHJ-40 Concrete Strength Tester (Concrete Pullout Tester)

Abbreviation: Concrete Pulling Instrument (Pulling Instrument)

Function: Mainly used for testing the strength of concrete (C10-C80) in construction projects, testing the bonding strength of decorative tiles, and on-site testing of other related tensile strength.

Features:
(1) The oil circuit is completely built-in, making the appearance simpler. It can avoid the reliability decline and easy damage of the instrument caused by external oil pipes, and is an updated product for the series of multifunctional strength testers currently sold in the market.
(2) We use our company's latest developed intelligent digital pressure gauge, which has data storage, query, and peak holding functions. It is calibrated using software and does not require disassembling the pressure gauge. When the external force reaches the specified pressure, simply press the "Set" button to complete it. It is currently the only on-site portable multifunctional strength tester on the market with this function, which greatly facilitates user calibration and use and is highly popular.
(3) Adopting the principle of "post installation pull-out method" for strength testing, this principle is the standard test method for testing the compressive strength of concrete in China, which complies with the "Technical Specification for Testing Concrete Strength by Post installation pull-out method" (CECS69:94). When the concrete has a certain strength, it can be tested at any time.
(4) In accordance with the "Standard for Testing the Bonding Strength of Decorative Bricks in Building Engineering" (JGJ110-97) and the "Code for Construction and Acceptance of Exterior Wall Decorative Brick Engineering" (JGJ126-2000) (5), many places have established strength measurement curves. This testing method has been widely used by various quality inspection and testing units and laboratories nationwide
(6) Each instrument is marked with legal measurement units before leaving the factory and can be used directly. The pressure gauge displays in kN
