Frequently Asked Questions (FAQ)
-
What is the difference between a Total Immersion and a Partial Immersion thermometer?
Answer: A Total Immersion thermometer is designed to be fully submerged in the liquid up to the level of the mercury column to achieve its specified accuracy. This model is essential for alcoholometry because it ensures the temperature is measured at the same depth as the hydrometer, providing the most accurate results for CRA excise duty calculations. -
Is this thermometer supplied with a Certificate of Calibration?
Answer: Yes, this thermometer comes with a Manufacturer's Statement of Accuracy, confirming it was manufactured and tested to meet the specified standards. We also offer ISO/IEC 17025 accredited calibration certificates as an optional add-on service. Please contact us for details. -
How often should this thermometer be recalibrated for CRA compliance?
Answer: For critical, regulatory work like CRA alcoholometry, we generally recommend recalibration annually (every 12 months). However, you should always consult the specific requirements of your internal quality control procedures or regulatory body to determine the appropriate interval for your application. -
What are the proper steps for cleaning this glass thermometer?
Answer: Carefully wipe the glass stem with a soft cloth and a mild soap or a standard laboratory solvent like isopropyl alcohol. Ensure no residue remains. Always handle the thermometer by the top of the stem and store it safely away from heavy equipment to prevent breakage. -
What special handling or disposal procedures are required for this mercury-filled thermometer?
Answer: This thermometer contains a small amount of elemental mercury. It should be handled with care to prevent breakage. If breakage occurs, follow all local, provincial, and federal guidelines for mercury spill cleanup and disposal. -
Can I use this thermometer for general lab work outside of distillery applications?
Answer: Yes. While optimized for CRA alcoholometry, this total immersion thermometer is a high-accuracy instrument suitable for general laboratory, process control, and bulk liquid temperature measurement within the specified range of -34 to 49 °C. -
Does this thermometer meet the requirements for official CRA (Canada Revenue Agency) records?
Answer: This is a high-quality instrument suitable for use with the Canadian Alcoholometric Tables to help determine spirit strength at the 20 °C reference temperature. Its design and resolution are appropriate for maintaining defensible ethanol tax records.
