Computrac Weight Set

We supply Class F weight sets with all of our Computrac^® moisture analyzers for balance calibration. Since customers occasionally have questions regarding the specification differences between Class F and Class 2 weights in the calibration of analytical balances, we have provided this brief explanation.

Internally, our staff uses Class 1 and Class 2 weight sets to calibrate and verify the operation of each unit prior to shipment. Typically, though, Computrac^® moisture analyzers are found on the production floor where they are operated and maintained by production personnel. Class 2 weights, which require special handling by trained individuals, do not encourage operational checks on the floor. Class F weights, on the other hand, promote the frequent checks necessary for accurate and reliable results, while providing tolerances that exceed our own specifications. They are a convenient, economical and easily handled alternative.

The Class F 3g and 5g weights supplied with all Computrac^® moisture analyzers are to be used as a calibration check only. This check tests the accuracy of the balance in measuring proportional weight changes. The tolerance for the weight test using the 3g and the 5g Class F weights is 37.50%, ± 0.02. In order for the weight test to be out of tolerance due to inaccuracies in the weights, the weights would have to vary more than 1.5mg from the 3g or 5g nominal value. Class F weights are rated to within 0.5mg of the nominal value. For the 20g calibration of the internal balance, the Class F weight has a tolerance of 0.8mg, this exceeds our internal specification of 20g ± 3.0mg.

New Parameter Settings For Sodium Tartrate

Incremental changes and improvements over the years to the MAX^® series units has changed the heating and measuring characteristics of these industry leading instruments. These changes include implementation of UL/CE approved electronics, improved heater wiring and connections, and updated firmware. To ensure a continuation of the highest quality testing available for our customers, the time has come to revise the testing parameters for sodium tartrate.

We have worked closely with our supplier to assure the highest quality sodium tartrate. We have also checked our own in-house protocols to verify that we are calibrating the units with the highest degree of accuracy. We are satisfied that the following minor change in the test parameters for sodium tartrate will bring the moisture value to the center of the acceptable range.

To change the value:

• Turn the instrument off for five seconds.
• Turn the instrument on and press the left most key below the display followed by the right most key. Press the Memry Key and select in order:
  • MEMORY START MENU
  • ADD/EDIT MEMORY START
  • 001 ID: TARTRATE
  • LIFT COMP PCT
    • Edit the value to 100 (100%)
    • Use the ESC key to return to the main Test Screen.
• Turn the instrument OFF then switch it back ON. The instrument is now ready to operate normally.

Pocket Pump for Dosimeter Use

Please be advised that we have changed Pocket Pumps in the Jerome^® Dosimeter Analysis Kit. We no longer will supply the Sipin Sampler Pump (AZI Part Number 2600-2011) with the kit. We will instead supply the SKC Pocket Pump (AZI Part Number 990-0177) with the Dosimeter Analysis Kit.

The SKC Pocket Pump brings our customers an intrinsically safe pump that has all required certifications and a sampling rate of 5cc/min. If purchasing a new Pocket Pump for you older Dosimeter Analysis Kits, remember that the old Sipin pump sampled at 2cc/min so the calculation in the Users Manual under the Dosimeter Analysis should be updated to reflect the new 5cc/min sampling rate. The current revision Users Manual is available on our website for free downloading.

Please feel free to contact our customer service department at 602-470-1414 or 800-290-1414, or contact Technical Support with any additional questions or concerns you may have regarding this or any other issue.

Ammonia Filter

Filter Performance (For Mercury Testing):

Between 4% to 6% reduction in Hg reading in the presence of 0.05 ppm to 50 ppm Ammonia levels.

Arizona Instrument recommends that no more than 1,200 liters of sampled air be drawn through the filter. After this accumulated volume, the moisture content will adversely affect the filter medium and produce phosphoric acid.

Total number of auto regenerations that can be performed before the filter is changed:

• 8 regenerations at 70 to 100% humidity.
• 12 regenerations at 41 to 69% humidity.
• 16 regenerations at 0 to 40% humidity.

If the instrument is operated manually, and the ammonia filter is removed for regenerations, the total number of samples can be increased by a factor of 60 each, 30 second samples, per regeneration.

The recommended total number of samples that may be taken through the filter:

• 800 samples at 70% to 100% relative humidity,
• 1,200 samples at 0% to 40% relative humidity,
• A proportionate number of samples between 800 and 1,200 may be taken at 41% and 69% relative humidity,
• The number of regenerations, with the filter in place in the instrument’s intake, should not exceed the above limitations.

Filter Performance (For Hydrogen Sulfide (h2s) Testing):

Less than 10% reduction in h₂s reading in the presence of 0.05 ppm to 50 ppm ammonia levels.

Arizona Instrument recommends that no more than 1,200 liters of sampled air be drawn through the filter. After this accumulated volume, the moisture content will adversely affect the filter medium and produce phosphoric acid.

Total number of auto regenerations that can be performed before the filter is changed:

• 40 regenerations at 70 to 100% humidity.
• 60 regenerations at 41 to 69% humidity.
• 80 regenerations at 0 to 40% humidity.

If the instrument is operated manually, and the ammonia filter is removed for regenerations, the total number of samples can be increased by a factor of 60 each, 30 second samples, per regeneration.

The recommended total number of samples that may be taken through the filter:

• 4,000 samples at 70% to 100% relative humidity,
• 6,000 samples at 0% to 40% relative humidity,
• A proportionate number of samples between 4,000 and 6,000 may be taken at 41% and 69% relative humidity,
• The number of regenerations, with the filter in place in the instrument’s intake, should not exceed the above limitations.

Safety information for Phosphoric Acid.

Health Hazard Data:

• Threshold limit value (tlv/twa): 1 mg/m³ (ppm)
• Short-term exposure limit (stel): 3 mg/m³ (ppm)
• Permissible exposure limit (pel): 1 mg/m³ (ppm)
• Toxicity: ld50 (oral-rat)(mg/kg) - 1530 ld50 (skin-rabbit)(mg/kg) - 2740
• Carcinogenicity: ntp: no, iarc: no, z list: no, OSHA reg: no
• Effects of overexposure: contact with skin or eyes may cause severe irritation or burns. Inhalation of vapors may cause severe irritation of the respiratory system.
• Target organs: respiratory system, eyes, skin
• Medical conditions generally aggravated by exposure: none identified
• Routes of entry: inhalation, ingestion, eye contact, skin contact

Emergency and first aid procedures:

• Call a physician.
• If swallowed, do not induce vomiting; if conscious, give water, milk, or milk of magnesia.
• In case of contact, immediately flush eyes or skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
• Wash clothing before re-use.

Dispose of used filters in a manner consistent with federal, state, and local regulations:

• RCRA D-Series Maximum Concentration of Contaminants: None listed.
• RCRA D-Series Chronic Toxicity Reference Levels: None listed.
• RCRA F-Series: None listed.

Chlorine Filter

Filter Performance:

The Arizona Instrument chlorine filter removes chlorine gas from the sample in amounts up to 6 ppm while not affecting either h₂s or mercury readings of the Jerome^® instrument or causing pre-mature degradation of the gold-film sensor.

The Chlorine filter was tested in excess of:

• Hydrogen Sulfide - 12,000 samples at 6 ppm chlorine at a flow rate of 150 ml/min, and
• Mercury - 2,400 samples at 6 ppm chlorine at a flow of 750 ml/min.

Filter Media:

Sodium Metabisulfite (Na₂S₂O₅) is used as a reducing agent to convert the chlorine gas to sodium chloride, sulfur dioxide and oxygen. These gases are not detected by the gold-film sensor technology, and therefore do not adversely interfere with the instrument readings.

Safety Data for Sodium Metabisulfite:

• Properly store in original, unopened container in a cool, dry location to provide almost indefinite shelf life.
• Take necessary precautions when handling/storing and disposing of filters. See MSDS
• Dispose of used filters in a manner consistent with federal, state and local regulations.
