Available for the measurement in deep well with small drill tools and high temperature: The diameter of standard external protecting barrel is only 25mm. Assembled with thermal insulation protecting barrel, the maximum pressure bearing capacity is 220MPa and the maximum working temperature is 260 ℃.(See details in below table).

Precise measurement, reliable stable performance: Equipped with shock proof accelerometer, the probe is featured with high linearity, small temperature drift, good repeatability and other characteristics, thus can ensure precise measurement data.

Particular Power-off protection: It will not affect the instrument's normal work if there is a sudden outage caused by special strong vibration or impact, which increases the success rate of the measurement.

Long working hours with low power consumption design: With the low power consumption design, a fully charged battery can guarantee a continuous working for more than 80 hours.

Good resistance to impact and vibration: The instrument is radially and axially equipped with multistage buffering devices, such as rubber, springs, hydraulic anti-seismic shock absorber, which effectively improves the impact resistance as well as the vibration resistance of the instrument.

Precise measurement, stable and reliable performance: The probe is adopted with high-precision acceleration sensor, which is in high linearity, good repeatability and other characteristics to ensure the probe-tube to get accurate and reliable measurement data.

Wide adaptability, lowprocurement cost: The same probe-tube can be used for multi-shot as well as for fixed-point measurement. Equipped with different downhole protecting system, it is available for self-floating measurement, suspending measurement and dropping measurement. It is very easy for the drilling teams to manage the instruments and reduce their procurement cost.
