12V500 Alcohol Breath Simulator The Guth Model

INTRODUCTION

The Guth Model 12V500 Alcohol Breath Simulator is a State-of-the-Art, electroni-

cally temperature controlled, water-alcohol instrument for the purpose of providing

a precise calibration standard for testing or calibration of alcohol breath analyzers.

The Model 12V500 is the first simulator of its kind to incorporate dual temperature

probes to independently control and monitor the temperature of the solution.  The

temperature of the water-alcohol solution placed in the simulator is maintained at

34° C ± .05° C or better.  The inlet and outlet port pathways have been designed to

be an integral part of the one piece heated aluminium top housing thus allowing

uniform heating and reduction of condensation.  The new LCD graphics display has

a temperature resolution of .01° C and will display simulator status to the user in

the form of messages and status codes.  As with all Guth products the 12V500 has

been engineered using the highest quality components to give reliable, accurate and

trouble free operation.

To establish a precise and accurate calibration standard when using a Guth Simulator,

GUTH LABORATORIES, INC. recommends using Guth Certified Simulator Solu-

tion.  Guth Laboratories, Inc., a pioneer and leader in the science of alcohol breath

testing, has provided Certified Simulator Solution to state, municipal, and local law

enforcement agencies for many years.

Guth Certified Simulator Solutions are prepared in standard concentrations of .02%,

.04%, .05%, .08%, .10%, .15%, .20%, and .30%.  Other special concentrations are

available upon request.  Please contact Guth Laboratories, Inc. for availability .

STORAGE:  Store Simulator Solution in a cool location.  Do not place

solution in a freezer.

- DO NOT REFRIGERATE SIMULATOR

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% (#9, Page 3).

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.

11. INPUT POWER JACK - The power jack serves as the input connector for

the external power supply.  The 12V500 can be run from the included desktop

switching power supply or any 12VDC source capable of supplying 8 amps.

12.  RS-232 COMMUNICATION PORT -The RS-232 port allows the simula-

tor to be interfaced with breath analyzers that support serial communications.

13. POWER SWITCH - The power switch is used to turn the simulator ON/

OFF.  It also functions as a RESET switch.

14. CALIBRATION PORT - The calibration port allows the temperature of the

solution to be measured with an external digital or mercury thermometer.

15. FEMALE INPUT CONNECTOR - The standard input connector is a

1/8” flow female SureLoc that allows for easy and secure hook up to various air

delivery methods. (Customized fitting options available)

16. MALE OUTPUT CONNECTOR - The standard output connector is a

1/8” flow male SureLoc that allows for easy and secure hook up for delivering

the calibration sample to various breath analyzers. (Customized fitting options

available)

17. POWER SUPPLY -  The included UL listed desktop switching power

supply is capable of accepting an input from 100 - 240 VAC and providing an

output of 12 VDC at 8.33 amps.

18. POWER OUTPUT CONNECTOR - The output connector  supplies power

to the 12V500.  This connector plugs into the power jack on the rear of the

simulator.

19. IEC60320-C14 - Accepts the female connector (IEC 60320-C13) for con-

necting the AC power cord to the power supply.

20. AC Power Cord - Used to connect the power supply to the AC power

source.

20a. NEMA5-15P - Plugs into wall socket or receptacle.

20b. IEC60320-C13 - Plugs into the male inlet (IEC 60320-C14) for

connecting the AC power cord to the power supply.
