SAFDY CO GAS DETECTOR
MODEL SCO11 (200ppm)
The Safdy range of CO gas detectors are used in the mining environment to continuously detect CO gas. The Safdy CO connects to a Telemetry System and displays the information on software Scada package.
CALIBRATION PROCEDURE
This calibration procedure is for clients that use the Anglo SSP system.
Clients include Driefontein East and West, Kloof and Libanon gold mines.
The Safdy CO Detector output is in the range of 0mA to 1mA.
The Safdy CO detector ZERO is electronically calibrated under laboratory conditions for an
output of 0,9mA at 0ppm CO gas.
The Safdy CO detector RANGE is calibrated for an output of 0,1mA for 200ppm CO gas.
The range from 0ppm to 200ppm CO gas, gives a linear output from 0,9mA to 0,1mA.
