Level calibrator

echometer

Magnitude Transfer Instrument-SHJ Echometer Calibrator Application Area It is mainly used to check test accuracy of liquid level, simulate chart-running speed, check chart-running error and stability, test sensitivity of microphone and other parameters of echometer. Test results can be printed out in report format. Features 1. Simple operation and user friendly interface make it easy to use and maintain. 2. It is widely used with full functions to meet calibration requirements of all kinds of echometer in the oilfileds. 3. Test error of liquid level and microphone sensitivity check can be realized through quantity check instead of qualitative analysis, which makes the results more convincing. 4. The instrument uses database to manage test results to ensure easy enquiry and print. 5. Its Software utilizes multi-threaded programming technology so that it can realize multi-tasking operation. 6. uses high-impedance matching technology to achieve more accurate sensitivity check of microphone. Main Technical Specifications 1. Resolution of liquid level test: 16digit 2. Pressure for microphone check: 0~2000Pa 3. Signal range of microphone check: -5V~+5V 4. Range of standard signal frequency and amplitude: 0.5~200Hz、0~1V 5. Working temperature: 0~30℃
