FLORITE 800
INSTRUCTION 16-9013
Installation/Operation/Maintenance
Rev. 1 – March 1999
Introduction
The Florite 800 is a battery powered, hand held instrument with a digital
LCD display capable of measuring the velocity, volume flowrate and tem-
perature of air by means of a thermal probe. The unit allows the airstream
area to be entered for volume measurement. Measurements may be dis-
played in either Metric or Imperial units as selected from the keyboard.
After selection, this will be 'remembered' by the instrument until reselected
from the keyboard. The attached thermal anemometer probe has a tip
diameter of 1/4" (8mm) and is, therefore, suitable for measurements at
grilles, slot diffusers and in small ducts where large access holes are not
acceptable. The velocity sensor in the probe is compensated for variations in
airstream temperature by means of a second thermistor which also senses,
and displays, the actual airstream temperature in either metric or imperial
units consistent with the units selected for velocity.
The instrument is supplied with batteries. Four 1.5 volt AA size cells are
required which may be either disposable or rechargeable types. Either
'Standard' or Alkaline disposable cells may be used but the 'Standard' type
will exhibit a relatively short life and are, therefore, not recommended. Low
battery condition is indicated by 'LOBAT' appearing on the instrument
display. The cells must be replaced as soon as possible to maintain optimum
accuracy. The battery cells are accessible by sliding the cover (at the rear of
the instrument case) in the direction of the arrow. A tape is provided in the
battery compartment for easy removal of the battery cells. Ensure that the
battery cells are replaced with the correct polarity as indicated in each cell
compartment. Rotate the cell slightly forwards and backwards to check that
the cell is properly seated in the cell compartment.
Operating the Florite 800
After switching the instrument on, it will go through a warm-up procedure in
which the entire set of display segments will light up and then the instru-
ment will count down from 9 to 0. If LOBAT is lit in the display after the
countdown the batteries need to be replaced.
All normal operating instructions can be seen on the rear of the instrument.

- Page 2 Zero the instrument With the zeroing cap covering the velocity thermistor to isolate it from any air movement, press ZERO. When zeroed the display ‘Press Zero’ will disappear. For optimum accuracy it is necessary for the instrument to be rezeroed with the probe at the operating temperature and zero velocity. To set a duct area Press the ‘vel /vol /area’...
- Page 3 Where to Use the Instrument Large Areas: When measuring velocity or volume flowrate over a large area, a number of readings must be taken, spaced to give an even coverage of the whole area. The average of these readings will give the mean velocity over the whole area or the mean volume flowrate.
- Page 4 Bacharach, Inc. for details. SERVICE AND RECALIBRATION: If a fault or the instrument’s calibration is suspected, it should be returned to Bacharach, Inc. for repair or recalibration. In any event, it is good practice to have the instrument checked at least once a year.
