three clear, sealable containers
one container with MgCl (Magnesium Chloride 32.8%, 50g) (salt refills also available for sale)
one container with NaCl (Sodium Chloride 75.3%, 50g) (salt refills also available for sale)
two wooden scrapers
an insulated carrying case to hold all of the above and maintain a stable environment while performing calibration
 
RE-CALIBRATION FREQUENCY? 
Answer: Dependent on whether it’s industrial use or consumer use. Acousticians recalibrate annually, firefighters annually or semi-annually, and general consumers might recalibrate them every 4 or 5 years or so. The official stance is that a calibration is recommended every 24 months due to the possibility of up to 2% calibration drift over 24 months.
 
TIPS
We recommend using boiling distilled water when mixing it with the calibration replacement salts, this process allows the water to be absorbed more easily by the salts, simplifying the process of achieving the slurry consistency required for the calibration process.
