Portable Gas Detector Testing And Calibration MANUFACTURED BY STATUS SCIENTIFIC CONTROLS Testing And Calibration of Portable Gas Detectors. 

In order to ensure the safe and accurate operation of Portable Gas Detectors, they need to be periodically calibrated against reference test gases that are traceable to National Physical Laboratory standards. The recommended calibration period for Status Scientific Controls gas detectors is six months although the frequency may need to be increased where continual exposure to the target gases is experienced. 
 
Between calibrations it is also recommended that the response of the detector is checked using an appropriate test gas cylinder. These cylinders are available in 'large aerosol' form and may be supplied individually or as part of a Field Calibration Kit. 
 
Status Scientific Controls offers a range of support equipment, including compressed gases, for the customer to carry out both calibration and response testing of the Portable Gas Detectors. 
Autocalibration Unit (Stock No.SS081) 
 
The Autocalibration unit is suitable for customers who own and calibrate a fleet of Portable Gas Detectors. It operates in conjunction with a PC running purpose designed calibration software provided by Status Scientific Controls. The use of high pressure compressed gas cylinders is required with this unit - these are available from a number of specialist companies who provide a certificate of composition traceable to National Physical Laboratory Standards with each cylinder. 
Warning - This unit is for use only within a safe area where potentially explosive gases do not exist. 
PC Interface Or PC Interface/Charger Units (Stock No.SS103) 
 
A PC Interface Unit or PC Charger/Interface Unit provides cost effective method of calibrating the Portable Gas Detector. It operates in conjunction with a PC running purpose designed calibration software provided by Status Scientific Controls. Test gas cylinders, regulators and sampling adaptors are required in order to present known reference gas levels to the instrument. These are available from Status Scientific Controls either individually or in kit form. 
Warning - This unit is for use only within a safe area where potentially explosive gases do not exist.
