Humidity Meter (Measure the Parameter of
Environment)

• Will it see low humidity each manufacturer has a
  unique sensor element bug most commonly used
  technology is capacitive. This humidity meter has
  the faster response time to notice the changes in
  the humidity and read accurately at a low level
  of humidity as well.

• Are any chemicals or contaminants present Each
  sensor has weakness and strength with certain use
  of the chemical. So, it is recommended for you to
  know the list of chemicals where the sensor will
  be installed. Compare the manufacturer
  compatibility chart. It will help you to select
  the right humidity meter.
• What accuracy is required It depends on the
  application of the gadget. Accuracy is a critical
  but important element of the gadget usage. You
  need to understand the complications of the
  accuracy. For example, if you need a higher level
  of accuracy in your work environments such as
  hospitals and labs. If accuracy is not your
  primary concern, then less accurate RH sensor can
  work also.

• What drift rate can I accept Drift is the
  inherent feature of the humidity meter and it
  occurs over time due to humidity meter features.
  This happens with the regardless of the
  manufacturer concern and it is recommended to
  select the sensor with low drift value of less
  than 1 per year.
•  
• What is the operating temperature range Is the
  sensor is installed in the narrow temperature
  range such as an operating room? Do you want to
  install in outdoor or duct applications where it
  can see a wider range of temperature? Consider it
  before your selection.
•  
• Does the meter have temperature effect and is it
  compensated Manufacturer compensates with the
  Humidity meter as they are all affected by the
  temperature. This temperature effect is expressed
  as C or F. Most humidity meters are calibrated
  at 77F(22C). So, it is recommended to select
  low-temperature effect humidity meter.

• How does the manufacturer calibrate the sensor
  Is it NIST traceable?- Each manufacturer has a
  different calibrated meter. Many meters are
  manual calibrations at only 3 RH values. The best
  humidity meter is digitally calibrated at
  multiple RH values against NIST.
•  
• Can the humidity meter be recalibrated in the
  field Due to quality, drift and installation
  environment, RH sensor needs to be recalibrated
  or can be replaced? These do not have the
  additional cost but surpasses the original
  purchase price if consider at the beginning of
  the project. Most humidity meter can be
  calibrated with the use of a potentiometer. The
  solution is to have interchangeable humidity
  meter which is computer-calibrated and are less
  expensive and does not require additional devices.
