Digital Track Gauge can directly read the measurement values of railway track gauge, super elevation , check rail gauge, back to back distance and flangeway clearance through microelectronics, embedded and sensor technologies and OLED display screen. FEATURE 1. Large LED backlit display: especially suitable for day outside and dark night 2. Quick calibration operation: simple measurement process 3. Large capacity battery:long standby time 4. Accurate measurement:keep long-term stability 5. Temperature compensation :working temperature is -30~+55â?? 6. Insulated design 7. Anti-electromagnetic interference 8. Waterproof:could use in rainy day 9. power saving function: no operation within 15 minutes, the system will automatically shut down. 10. Approval by CHINA ACADEMY OF RAILWAY SCIENCES 11.1000mm,1067mm,1435mm,1520mm,1600mm,1676mm track gauge is available.
