Calibration |
Each unit includes a report of calibration traceable to
NIST. |
For determining fogging characteristics of automotive interior trim use
the Hart Scientific Model 0011 Fog-Test Chamber. The Model 0011 complies
with the newly adapted SAE J1756 “Test Procedure To Determine the Fogging
Characteristics of Interior Automotive Materials.”
Without using messy oils or external cooling hookups, the Model 0011 operates
completely dry. This eliminates any fear of bath oils entering into your
test results.
Two separate precision temperature controllers maintain the stability of
the heating block and cooling plates. Cooling is done through the use of
electronically controlled solid-state thermoelectric devices, not an external
water bath.
The 0011 is completely self-contained and compact, using only 19" x 14"
of bench space. Glassware and samples are easily loaded and unloaded into
the test wells without fear of oil deposits or spills.
Setup is quick and easy with the Hart Fog-Test Chamber. Since there are
no external tubes to connect or oil levels to check, simply set the desired
temperature on the control panel and when the unit stabilizes you are ready
to load your samples.
Each Hart Fog-Test Chamber ships complete with everything you need to get
started collecting fogging data. Also included is an instructional video
and a certificate of calibration.
The Competition’s Approach to Fog Testers |
Hart’s Advanced Fogger Design |
Messy Bath Oils
Liquid temperature baths or circulators used to heat the
test beakers and the cooling plates can deposit oily films on the test
glassware that are difficult to remove and can potentially contaminate
your dishwasher. This is inconvenient, and the oil deposits can alter the
fog readings. |
Hart’s fog-chamber employs dry heating and cooling. The test wells are
placed in a heated block assembly and the cooling plates are cooled with
solid-state thermoelectric devices. No fluids of any type are used. Therefore,
no oil contacts your glassware or contaminates your data. |
Difficult Cleaning And Maintenance
Bath oils create general cleaning problems
and they are expensive to replace. The baths must be drained and cleaned
at least annually. |
The heating and cooling assemblies in the Hart fog-chamber require no maintenance. |
Cumbersome Plumbing Connections
The liquid circulator and each cooling plate
are connected with a series of tubes that are easily disrupted. Frequent
checks must be made to assure proper liquid flow through the tubing and
the absence of leaks. |
Hart’s solid state cooling requires no plumbing at all. Less complexity
means fewer problems. |
Temperature Gradients
Temperature uniformity is critical to the fog test.
Each beaker must be heated to the same temperature within a given tolerance
and each cooling plate must also be consistent from one to the next within
that tolerance; otherwise fogging rates between test beakers will be distorted.
In liquid-bath fog testers, bath fluids are circulated in the heated bath
by a pump. The test beakers themselves interfere with the flow of fluid
and create the potential for non-uniformities between the test beakers.
On the cooling side, the cooling fluids have actually left the control
segment of their loop before they pass through the cooling plates one to
the next. Temperature change can occur between the point the fluid leaves
the bath/circulator and between each cooling plate. |
The Hart system employs a careful balance between the mechanical design
and heater placement to ensure that each test well is at the same temperature
at any given moment. The cooling plate design applies the same cooling
power to each plate simultaneously. |
No Authoritative Calibration of Temperatures
No calibration or standards
traceable test is provided to assure uniform temperature performance and
accuracy. |
Each Hart tester is accompanied by a certificate of calibration traceable
to NIST (formerly NBS). Hart manufactures and markets temperature standards
to the government and the Fortune 500 and is well equipped and experienced
to provide authoritative calibrations. Each test well and each cooling
plate are individually tested under fog test conditions and actual data
are reported on the certificate. |
Misleading Temperature Indication
Temperatures are set using a digital controller
found on the bath and circulator. Although this display gives an “actual”
temperature, it is only the temperature of the bath oil at one location
in the bath (next to the heater/cooler). It does not give the actual temperature
in the test beakers or at the cooling plates. |
Temperatures are set on the Hart fogger using push buttons, digital display,
and controls that have been calibrated (per the supplied certificate) so
that the temperature set is the actual temperature found in each test beaker
and at each cooling plate within the tolerance allowed by the published
fog test methods. An optional calibrated thermometer and sensors are available
to reassure the user through the use of actual measurements. |
Lab Space
The liquid bath fog tester takes considerable bench space for
the bath and its circulator. It’s difficult and awkward to move. |
The Hart fog tester occupies about half the bench space of a bath unit.
It is completely self-contained and easily moved. |
