HWHS-6SP Concrete Restricted Expansion Rate Tester Introduction: Widely used for measuring the shrinkage and expansion of building materials such as cement, mortar, concrete, putty, gypsum, etc. in a constant temperature and humidity environment. The equipment collects data through displacement sensors and displays it on a computer for storage. Can be used for long-term monitoring. characteristic: 1. High precision displacement sensor: accuracy 0.001mm 2. Measurement channels can be expanded: 1 channel, 2 channels, 3 channels, 6 channels, 9 channels 3. The measurement time can be set arbitrarily. Meet different age groups. 4. No need for manual monitoring, data is automatically saved. 5. The experimental data can be saved in Excel software. 6. Simultaneously record the test time, temperature and humidity of the test environment, specimen number, age, and original length of the specimen. Technical Parameter: Displacement sensor range: ± 2.5mm Displacement sensor measurement error: ± 1um Temperature measurement range: 0℃~50℃ Temperature measurement error: ± 0.5 ℃ (25 ℃) Humidity measurement range: 0~100%RH Humidity measurement error: ±3%（5%RH~95%RH，25℃） Temperature range: 5 ℃~50 ℃ Temperature fluctuation: ≤ ±0.5℃ Temperature accuracy: 0.01 ℃ Temperature uniformity: ≤ 2℃ Humidity range: 20% RH to 98% RH Humidity accuracy: 0.1% RH Studio size: 620 × 550 × 1300mm (width, depth, height)
