Calibration: After sample has been cleared
press Clear, enter the calibration
code, 3434, then press Enter
Security: Keypad function can be
selectively limited to Start/Stop
and Units, in order to prevent
changing of sample presets.
DESCRIPTION
The RADēCO Model H-810BL is a dependable, lightweight air sampler which
incorporates the reliability, ruggedness, and technology of the Model H-810DM with an
IntelliGen brushless blower for continuous high volume sampling as well as standard
grab samples.
The H-810BL uses an Air Volume Totalizer composed of an enclosed air-turbine, which
rotates at speeds proportional to the air velocity of the sampled air. The turbine’s rotation
is sensed by a reflective sensor/breaker disc. The microprocessor converts the signal to
volume and displays the flow rate, total volume and elapsed time on the LCD readout.
The Model H-810BL may be operated in either the “Total Volume” mode or the “Total
Elapsed Time” mode with the mode of operation selected during instrument calibration.
The functions/parameters that are established during calibration may be locked-in using
the “keypad security” feature. When keypad security is enabled, the SET function on the
keypad is disabled, which prevents the operator from altering the sample presets.
The operation of the Model H-810BL is a very simple four-step procedure and the
training time required is relatively short. Its operational procedure is:
1. Connect to an AC power source.
2. Install the sample holder with the filter media.
3. Turn power switch on.
4. Press the START key.
The Model H-810BL samples the environment until the desired total volume or total
elapsed time has been reached and then turns itself off. The LCD readout indicates the
total volume and elapsed sample time. A STOP key is provided to stop the sampling
procedure at any point during the sampling period, and the total volume of air sampled,
and elapsed time up to that point are indicated.
