一种新型土白蚁巢探测仪

A new type of detector for Odontotermes spp. nests

利用土白蚁巢内气体CO2浓度是空气中CO2浓度20—333倍的特性，提出全新的土白蚁巢气体探测技术，即通过蚁道抽取蚁巢内气体，测量其CO2含量，从而达到探测土白蚁巢的目地，据此成功研制了土白蚁探测仪，该探测仪重量〈2kg，探测所需时间〈1min，使用环境温度-10℃-50℃，探测准确率100％。

The carbondioxide density in Odontotermes spp. nests was 20-333 times as that in the air. According to this chaxacteristic, a new technique for detecting gases in termite nests was developed. It collected the gases in the nests through the termite way and measured their carbondioxide density to detect nests. Based on the technique, a new type of detector for termite nests was developed. The detector weighed less than 2 kg. The time for detecting the gases was less than 1 min and the operation temperature was between - 10 ℃ and 50 ℃. The accuracy of the detector was 100%.
