Concrete Air Content Meter
Premium Craftsmanship & Manufacturing Technology
This direct reading concrete air meter is produced with mature industrial precision craft, strictly following international concrete test standards throughout the whole manufacturing process. All pressure assembly parts adopt CNC one-time machining to guarantee matching tightness without air leakage. The internal pressure calibration process is finished under constant temperature workshop environment, each instrument undergoes repeated air tightness and pressure detection before delivery to eliminate measurement deviation. The welding joint of the tank body is polished smoothly, anti-leakage and anti-corrosion treatment is carried out on the inner wall, avoiding residue buildup after long-term contact with concrete slurry. The pressure gauge is calibrated by professional metering equipment to ensure long-term stable data reading, meeting high-standard testing demands of engineering labs and large construction projects.
High-Grade Material Configuration
1. Main testing tank: High-strength cast aluminum alloy main cylinder, light weight while possessing strong pressure resistance, outer surface with electrostatic baking paint to resist oxidation and scratch.
2. Sealing components: High temperature resistant silicone rubber sealing rings, excellent elasticity, long service life, effectively prevent gas leakage during pressure holding test.
3. Pressure gauge: Stainless steel shell precision pressure dial, anti-shock internal structure, clear dial scale, resistant to workshop dust and water mist erosion.
4. Locking clamping mechanism: Forged carbon steel fasteners, high structural strength, not easy to deform after frequent disassembly and locking operation.
5. Supporting accessories: Transparent graduated measuring cylinder made of thickened high-hardness plastic, rubber inflating bulb with good air tightness, all matching parts are wear-resistant and easy to clean.
Core Product Functions
The instrument is used to accurately measure the air content inside fresh mixed concrete, evaluating the air entraining effect of concrete admixtures, which guides concrete mix proportion adjustment for roads, bridges, tunnels and hydraulic engineering. It supports testing of ordinary concrete, air-entrained concrete, lightweight aggregate concrete and mortar samples. The built-in pressure balance structure realizes direct reading of air content data without complex conversion calculation. It is equipped with independent pressure relief valve and inflation valve, which can control internal air pressure stably during testing. The fully enclosed testing chamber avoids external air interference and ensures consistent and repeatable test results. The complete set of accessories can finish the full test process of water injection, inflation, pressure stabilization and reading without extra auxiliary tools.
Easy Operation & User-Friendly Design
The overall operation flow is simplified, no complex professional training is required for operators. Multiple quick-lock clamps are evenly distributed around the tank cover, which can fast lock or open the cylinder body within seconds without complicated twisting tools. The independent hand-held inflating bulb separates inflation operation from the main tank, making pressure adjustment more labor-saving. The large dial pressure gauge is placed at the top of the equipment, presenting readings in a visible horizontal angle to avoid visual error. After each test, the smooth inner tank wall can be rinsed quickly with clean water, and the disassembled sealing ring and accessories can be cleaned and stored easily. The test steps are standardized and concise, which greatly shortens single-group test time and improves daily laboratory detection efficiency.
Professional Protective Packaging
The complete set of instrument is equipped with customized solid wooden storage box as standard export packaging. The wooden box adopts thickened multi-layer plywood with metal edge wrapping and metal lock buckles, strong compression resistance and anti-collision performance, which can effectively buffer collision and extrusion during sea and land long-distance transportation. The box interior is customized shock-absorbing lining, which fixes the main tank, pressure gauge, measuring cylinder and rubber bulb separately to avoid friction damage during transit. The wooden box surface is printed with product name and specification information, convenient for warehouse classification and customer receiving inspection. The outer layer can be added with export carton packaging according to customer demands, which fully meets overseas cross-border logistics and customs transportation requirements.
FAQ
Q1: What Testing Standards Does This Concrete Air Content Meter Comply With?
A: It meets GB/T 50080, ASTM C231 and ISO related concrete fresh mixture test standards, and we can provide CE certification documents for overseas engineering inspection companies and contractors.
Q2: Will Air Leakage Occur During Long-Term Testing?
A: The equipment uses silicone sealing rings and CNC precision machined fitting surfaces. Every finished product will pass air tightness pressure test before leaving factory. As long as the sealing ring is kept intact, there will be no air leakage during normal use. We also supply spare sealing rings as matching accessories.
Q3: What Kinds Of Concrete Samples Can This Tester Measure?
A: It is suitable for all fresh plastic concrete, including air-entrained road concrete, hydraulic concrete, lightweight aggregate concrete and construction mortar, widely used in highway, bridge, dam and building engineering testing laboratories.
Q4: Is The Wooden Packaging Box Suitable For Sea Freight Export?
A: Yes, the standard solid wooden box has anti-collision and moisture-proof performance, and can be directly used for international sea and land transportation. If customers need fumigation-free packaging, we can provide plywood export boxes without fumigation certificates.
Q5: How To Maintain The Equipment To Extend Service Life?
A: Clean the inner tank with clean water right after each test to remove residual concrete slurry; regularly check the elasticity of silicone sealing rings; avoid strong impact on the pressure gauge during moving; store all accessories in the matched wooden box when not in use for long periods.
