With a portable design, you can detect gas leaks easily. Simply place the probe near the detection area for instant confirmation of any leaks.
Not only can it detect gases with a significant difference in thermal conductivity from air, such as helium and carbon dioxide, but it can also detect nitrogen, which has a smaller difference and is more difficult to detect.
In addition to standard battery operation, continuous operation via USB-C power supply is also possible. Even when the batteries run out, you can use it while supplying power from a PC’s USB port or a mobile battery.
Note 1: USB cable is not included.
Note 2: USB power supply does not support charging functionality
