40 - 300mm 1.5% F.S Software Controlled 3 Arm Caliper Probe

40～300 mm 1.5% F.S Software-controlled JJY-3D 3-Arm Caliper Probe

Description

The 3-Arm Caliper probe records a single continuous borehole diameter log by means of three mechanically coupled arms in contact with the borehole wall.Also equipped with liquid level detection electrode, Measure the depth of the liquid level in the borehole.Liquid level depth and caliper is the important parameters of hydrological survey well logging information.

Operating Conditions:Uncased；Borehole Fluid:Dry, Water or Mud

Features & Benefits

1. Opening and closing of the motor-driver caliper arms is by surface command, allowing the probe to run into the borehole with the arms retracted.

2. Easy exchangeable caliper arm lengths and wear tips

Applications

Rock integrity evaluation

Fracture and cavity localization

Borehole diameter measurement

Borehole volume calculation before borehole completion, cementation

Often used in the implementation of environmental correction equations for other logs
