Brief introduction TRA10 type portable light transmittance tester is to customers used conveniently as a starting point, on the VT100 (m) model improved. This type of light through rate meter, the biggest advantage is no need for installation and commissioning, electricity can be detected, the LCD screen on the display of test data in real-time. Considering to the tunnel in the harsh natural environment, do not facilitate synchronous connection notebook computer to store data and instrument built-in memory can automatically save the test data, after the completion of the detection, instrument back to the lab, connected to the computer, by light transmittance display software to automatically instrument internal memory to save the data into the computer, and to excel format save, so that customers access to use. Features Applicable to all kinds of atmospheric environment, atmospheric light transmission rate, the visibility of various atmospheric environment, the visibility of the value of the tunnel, the VI value of the acceptance test Technical parameter Model: HY-TRA10 Test range Optical transmittance (T): 0-100% The visibility (VI):1-5000 M The smoke concentration (K):0-35*10 3 1/m The concentration of CO (CO):0-300 ppm Ambient temperature: -40 degrees C - +80 Ambient humidity: 0100% Status display: 128*64 dot matrix LCD screen, digital and character display Test principle: optical transmission method, digital probe, electrochemical probe Test error: + 2% light transmittance (full range) Ambient temperature: -55 ~ 65 degrees Celsius Ambient humidity: 0 ~ 100%RH Communication interface: RS232 / RS485 / USB Power supply voltage: 220V AC adapter (the built-in rechargeable lithium battery, in the case of no external power supply, work for more than 10 hours) Data storage: 70 consecutive hours of testing data can be stored The detection cycle: 2 s (can be customized according to customer requirements) Storage period: 10 s (stored in this machine) Machine weight: 16KG (including instrument, instrument box, theodolite support)
