About us

BAC Corrosion Control has introduced a new Windows compatible version of its highly reputable Surveyor System which enables a complete pipe to soil potential profiles over an entire pipeline length by recording data every one to two metres for high accuracy.

The new Mark 10 Global Surveyor system has simple-to-use MS Windows® based, printer friendly data management software. The latest chips, processors and oscillator have been incorporated into the Mark 10 which has a new ergonomic enclosure. Battery life has been increased by 30% and input impedance has been improved to eliminate all "noise". The new software is compatible with the full range of Global Surveyor equipment and although included in the price of the Mark 10 System,  it is available separately for use with earlier systems. The system has 750Kb of memory and a full QWERTY keyboard is included.

The software has been specially designed to enable downloading, editing, saving and printing of data collected from close interval (CIP) and DC voltage gradient (DCVG) surveys.  It is compatible with MS Windows® 95, 98, NT 2000 and XP operating systems and requires a minimum computer specification of 300MHz processor with 32MB of RAM.  Being MS Windows® based the software will print directly to any suitable printer (colour or mono) negating the need for costly dedicated plotters.

BAC's Global Surveyor System has been purpose built by cathodic protection engineers who understand the requirements for effective field work and cathodic protection data accuracy. The Surveyor System forms a complete package and comprises a data logger synchronised to the current interrupter, synchronised switchers to an accuracy of ± 4 milliseconds a day, a cable dispenser with automatic distance incrementing and special high insulation re-usable lightweight cable. 

Together with its specialist data handling software the Surveyor data logger has the very highest specification available for field instruments.   Input impedance is switchable between 10 and 1000 megohms and the common mode rejection is better than ± 1mV for any DC input (operating range) and better than 100dB at 50-60 Hz for 10V AC output. Normal mode rejection is better than 60dB at 50-60 Hz for 10V AC output and the voltage accuracy is 0.1% FS.
