RJD-3 Horizontal Shrinkage Expansion Instrument Introduction: The fully automatic shrinkage and expansion test monitoring system can be used for measuring the shrinkage and expansion of materials, and is suitable for shrinkage and expansion tests of various metal or non-metal materials, building materials, rubber and plastic materials, etc. The device collects data through displacement sensors and displays and saves it on the computer. Can be used for long-term monitoring. For the construction and building materials industry, this equipment can meet the requirements of materials such as cement, mortar, concrete, putty, gypsum, and self leveling. Characteristics: 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 parameters 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℃）
