COMPONENTS & FUNCTIONS
1. TOP HOUSING
- The top housing incorporates all the important features
of the simulator. The housing is heated and controlled by use of a head space
heater (U.S. Patent # 8,667,829).
2. LCD DISPLAY
- The display indicates the temperature of the solution with
a resolution of .01° C. It also serves to give feedback to the user during use by
displaying status messages. The display is back lighted to allow easy viewing in
all lighting conditions.
3. TEMPERATURE PROBE
- The temperature probe consists of two separate
ultra-stable precision thermistor beads. One thermistor bead is used to control
the temperature of the solution at 34° C ± .05° C and the other independently
monitors the temperature of the solution. In the event of either probe failing a
status message is generated on the display.
4. HEATING ELEMENT
- The heater element is used to heat the solution to
34° C. It is electronically protected from overheating if the simulator would be
turned on without solution in the container. In the event of a heater failure a
status message will be generated on the display.
5. BAFFLE PLATE
- The baffle plate prevents excess solution from entering
the head space or outlet port during a test.
6. AGITATOR
- The agitator designed by Guth Laboratories, Inc. stirs the solu-
tion to help maintain a uniform temperature. If the motor fails a status message
will be displayed on the screen.
7. DISPERSION TUBE
- A unique dispersion tube disperses the delivery air
uniformly throughout the solution. Tube may be disassembled for cleaning.
8. GLASS CONTAINER
- The glass container holds the solution and creates
an airtight seal with the top housing. There is a mark on the container indicating
the solution level at 500 ml ± 5%

10. U.H.C. (Uniform Headspace Conditioner) -
To ensure all tests performed
by the Guth Model 12V500 are precise and accurate, an eight (8) blade radial
fan is designed and included in the headspace area. The headspace area is heat-
ed by an imbedded controlled heater. The radial fan provides uniform headspace
heating and the effluent at a constant concentration.
Patent Pending.
