ACM-6

ACM-6 Self-contained digital manometer-thermometer

Destination.

АЦМ-6 designed to record pressure and temperature in the hydrodynamic studies in the process of drilling and operation of oil and injection wells.

The tool measures pressure and temperature at set intervals of time and records the digital information in the nonvolatile electronic memory. The pressure sensor at the same time is a temperature sensor.

After the measurement data is read into the computer for processing, analysis, display (printer) in graphic or digital form and transfer to other treatment programs.

ACM-6 has a high-resolution pressure due to the 19-bit ADC; has a memory of up to 8Mb and interface communication with PC USB2.0 (read time total memory not more than two minutes);

ACM-6 has three modes of operation "economic" (minimum current consumption), "precise" (the maximum sensitivity of the pressure channel), "high-speed" (for measuring rapid pressure changes); 

There is a modification of the tool with an additional external temperature sensor and water hold up sensor.
