Company Profile

Function: The instrument is mainly used for determining temperature in the borehole. Lower down the temperature probe into borehole using cable, so that we can get temperature-depth curve from controlling unit. The temperature can be applied to divid

Main
Technical Characteristics:

1. Probe:

(1) Size:
Φ40mm×800mm;

(2) Pressure
endured: 15 MPa;

(3) Measurement
