Gamma Sensor

Information
The Gamma sensor is mainly used to measure the intensity of gamma ray to identify the formation in geosteering for oil and gas development engineering.

Features

● It uses a super-sensitive hermetically-sealed NaI scintillator crystal and durable high temperature           photomultiplier tube
● Detector design minimizes vibration and shock
● Self-development and customizable
● High sensitivity and repeatability  
● Low power operations maximizes MWD battery life                          
● Compact and rugged
Application
● MWD System                          
● Electromagnetic MWD System
● Geosteering System
● Near-bit measurement System
