Tetra Flow sampling

Pumped instruments

Tetra’s inbuilt pump draws sample air in through the inlet nozzle of the flow

adaptor plate and out through the outlet nozzle. When using sampling equip-

ment, if the inlet should become blocked with dirt, water or a kink in the line,

the pump will automatically stop. Tetra will emit a rapid series of beeps and

display a warning message. To restart the pump, clear the blockage and press

the operator button.

Diffusion instruments

When using the manual aspirator kit, adopt a consistent style whilst using the

hand aspirator. Crowcon recommend squeezing once per second to achieve a

flow rate of approximately 0.5 - 1 litre/min. At least 10 pumps per sample are

recommended.

Extension probes, drop lines

and water traps are available.

See accessories section XI.
