Description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the structure diagram inside detector.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, the detecting instrument of soil pollution object, including feeler lever 3, gas-guide tube 2 and detector 9, feeler lever 3 is inserted into
One end setting gas introduction port 11 of soil, other end connection gas-guide tube 2 lead and dust filter unit 1 are provided on device pipe 2, visit
Data export interface 10 is set on bar 3, and data export interface 10 is connect by data line 5 with detector 9, and export feeler lever is surveyed
The temperature data of examination, be provided on detector 9 gas outlet 8 and with 2 matched air inlet 7 of gas-guide tube, detector 9 can by into
Gas port 7 is connect with gas-guide tube 2, and multifrnction connector 6 is provided on detector 9, and multifrnction connector 6 can connect data export
