Choose a precise and stable second cla laser, as close as 5m and as far as 40m. Double-iue Single-receive , mm Measurement Accuracy Double-iue Single-receive laser, laser emiion-calibration-display data, the accuracy can reach 3mm. Double-iue Single-receive , Laser Accuracy House Measurement , Soft Package Measurement Decoration Measurement , Furniture Measurement Mijia APP , Multiple Functions Connect the mobile phone via Bluetooth and link with the Mijia app to realize data synchronization/remarks, length/area/volume calculation, floor plan surveying and mapping, drawing sharing and other functions. * Rangefinder to connect the Mijia app, need 6.9.200 version or higher. Floor Plan / Real Scene Painting Measurement You can directly draw a floor plan in the Mijia APP or take real photo and then draw and measure. The measured data is automatically marked to the selected line, APP intelligently adjusts the length of the line according to the marked data. Area / Volume / Length Calculation You can flexibly select the existing length, width, and height data for area and volume calculations, and you can also simply add and subtract to calculate the length. Remote Measurement The mobile phone can be used as a "distance finder remote control" to remotely control the rangefindermeasurement. It is suitable for the scene where the rangefinder/human-machine separation must be placed at a fixed point.
