Sensidyne / Gilian Gilibrator
Calibrator
Primary Standard for the Calibration of Air Sampling Equipment
The Gilibrator System from Gilian is an easy to use
Primary Standard for the calibration of Air Sampling equipment. This unique
system features 3 interchangeable flow cells that incorporate twist on/off
mounting and a micro-processor control unit.Individual
flow cells provide consistent pulsation free bubbles and the built in
infrared sensors activate instantaneously to indicate the flow readouts on
the Control Units LCD display. The 3 Flow Cell ranges are: High (2-30 LPM)
Standard (20cc-6 LPM) and Low (2-250 cc/min.).The
control unit also offers useful microprocessor functions that include
Auto-Averaging of multiple flow readings and a Flow Delete function that
will subtract false readings from the average and reset back to the previous
value.
The new Gilibrator system is the only airflow calibrator
with interchangeable flow cells. This unique Gilian design allows you to
choose from three individual flow ranges.
- High (2-30 LPM)
- Standard (20cc-6 LPM)
- Low (1-250 cc/min)
The Gilian Gilibrator electronics are programmed to
calculate the air flow rate, average flow rate, and the test number of each
sequence automatically. A manual Delete function will subtract erroneous
readings from the average. The Gilibrator's control unit base features a
large easy-to-read LCD display and select buttons for easy calculation of
data. An auto-averaging button automatically averages the data during the
calibration period. It states the number of calibrations and the average
flow rate. The Delete button allows the erroneous bubble reading to be
removed from the running average, and reset back to the previous reading. A
reset button is a quick way to initialize a new calibration sequence and set
the display back to zero.
Features:
- Interchangeable flow cell mount
Each cell is designed to twist onto the electronics base. This enables
you to install each cell quickly, without screws or clips.
- Automatic bubble generator
At the base of the flow cell is the bubble generator. By pushing the
button down, a ring lowers itself into the soap solution, creating a
perfect film. Releasing the button lifts the film to the flow tube
automatically.
- Built-in infrared bubble sensors
This feature senses when the bubble passes the lower sensor, then the
upper sensor. The electronics then calculate the flow rate of the bubble
and indicate the reading on the LCD display.
- Interchangeable flow cells
The new Gilibrator system is an easy-to-use primary flow calibrator.
This unique system features three interchangeable flow cells that
incorporate twist on/twist off mounting. This allows the user to buy one
unit and simply switch the flow cell chamber for a specific calibration
range.
Flow cell ranges include a high flow of 2-30 LPM to calibrate large
scale high volume samplers. A standard range will cover most of your
flow equipment ranges from 20cc-6LPM. For ultra low flow calibration,
Gilian offers a 1-250cc/min flow cell ideal for calibrating samplers
with sorbent tubes in line.
- Pulsation dampers
The pulsation damper removes pulsation from the flow source for higher
accuracy sampling as well as eliminating pulsations back into the flow
source during bubble generation.
- Average, delete, and reset functions
Successive readings can be taken and the Gilibrator will automatically
average the readings taken during that trial. If an error is made due to
an improper bubble, that reading may be deleted from the average and
brought back to the previous average. To reset the system, which
initiates a new averaging sequence, simply press Reset.
- Run and charge LEDs
When the first infrared sensor is tripped, the RUN LED will light. This
will prevent you from inadvertently initiating another bubble during the
run. The charge LED indicates that the battery is being charged.
- Rechargeable battery system
This enables you to use the Gilibrator anywhere, in the lab or in the
field. When fully charged, the Gilibrator will operate for a period of
eight hours The unit can also be used on AC current.
