I have calibration quality CO2, but the concentration isn exactly 1000 ppm. Will I be able to use it to calibrate the Q-TRAK Plus?
Yes. The Q-TRAK Plus allows you to enter the concentration of the calibration gas and will automatically calibrate to that concentration. • I like the portability of the Q-TRAK Plus, but I am concerned about the possibility of tampering or theft during unattended monitoring.The Q-TRAK Plus is equipped with an inconspicuous display/keypad lockout switch which prevents unauthorized or accidental tampering during unattended operation. To prevent theft, some customers have hidden the main body of the instrument in the area above a suspended ceiling with the probe hanging down. Other ideas include a file cabinet, locked box, drawer, or other secured area.
