monitoring. Dickson has designed the chart recorder specifically for vaccine storage applications. Easy-to-
read charts clearly show when vaccines go out of acceptable temperature range and for how long. This
unique chart recorder highlights ranges for standard refrigerator vaccines (35 to 46°F) and freezer vaccines
as well (5°F and lower).

The Importance and Benefits of Regular Calibrations
Once you begin to use your precision Dickson instrumentation, regular calibrations are necessary to ensure
accurate readings.
The following Calibration Services are available:
N150 - NIST Traceable Calibration 1-Point: Includes documentation to one Dickson pre-selected
point after re-calibration.
N350 - NIST Traceable Calibration 3-Point: Includes documentation of three Dickson pre-
selected points (a high, medium, and low) after re-calibration.
N450 - Deluxe A2LA Accredited NIST Traceable Calibration 3-Point: ISO Guide 25/A2LA
Documentation of 3 pre-selected points of as found data before and after calibration for Dickson
temperature and/or humidity instrumentation.
N995 - NIST User Selected Temperature Points: Documentation of one customer specified
point. Should be selected in addition to one of the above calibration options.
Why should I recalibrate my instrumentation?
Over time dirt, dust and normal handling can throw your precision instrumentation out of calibration.
Regular calibrations ensure that you receive the most accurate readings possible.
How often should I recalibrate my instrumentation?
Depending on the environment your instrument is used in and how often it is handled you will want
to recalibrate your instrument every 2 years. Instruments in environments where there are extreme
temperatures, wide temperature ranges, humidity or pressure variations, high condensation, dirt, dust and
other debris will require calibration at least every 6 months. Instruments that are frequently moved or in
locations with heavy machinery that cause vibrations should also be calibrated at least every 6 months.
Why should I return my instrument to Dickson for calibration?
Dickson calibrates your instrument at the factory using proprietary production/calibration software that
guarantees proper calibration.
