Product Description:

The BT-B10JG-E Portable Laser Telemeter is composed of an opto-mechanical unit, a signal processing unit, a display and alarm unit, and a housing assembly. In the working state, the telemeter emits an invisible-to-the-naked-eye infrared laser beam to irradiate the detection point. By receiving the laser signal diffusely reflected from the detection point, it can quickly measure the concentration of the gas mass between the telemeter and the detection point. For the convenience of observation, the telemeter also emits a visible laser beam parallel to the infrared measurement laser, which is used to indicate the position of the current detection point.
This telemeter can detect the gas concentration at the inspected position in real time and accurately, and perform functions such as alarm prompting.


Product Features:

※ Lightweight design with ergonomic structure, enabling one-handed operation for convenient patrol inspection.

※ Measurement sensitivity of 5ppm·m, ensuring no tiny leak goes undetected.

※ Unique algorithm calibration, eliminating troubles caused by false alarms during daily use.

※ Maximum measurement distance of 200m (@30% reflectivity).

※ Precisely matched optical sight at the factory, allowing clear identification of the measured point position outdoors.

※ The infrared measurement laser can effectively penetrate double-layer glass, facilitating indoor patrol inspection.

※ Connects to mobile phones via Bluetooth; dedicated software can be used to record data and trace historical patrol information.
