Considering humidity accuracy measurements is necessary when selecting a relative humidity transmitter. Accuracy, by definition, is "the degree to which the result of a measurement, calculation, or specification conforms to the correct value or standard" (Oxford English Dictionary). When comparing accuracy measurements of different relative humidity sensors, understanding the factors included in said measurements is crucial. An accuracy measurement should consist of non-linearity, hysteresis, repeatability, and calibration uncertainty. These factors can be defined as:

An important consideration when choosing a T/RH sensor is whether or not it is critical to see the reading on the unit. Whether the sensor is to be wall, duct, or outdoor mounted has an impact on the need for a display, but it is not the deciding factor.

In hospitals, pharmaceutical compounding centers, and other sensitive healthcare environments, one of the biggest threats to patient health is the spread of pathogens. Exposure to viruses, bacteria, pollen, and fungi all pose hazards to patients and care providers and can compromise critical spaces like operating rooms and other procedure areas.

When selecting a humidity sensor, we recommend choosing one with a field replaceable tip. Why are we recommending this? A field replaceable tip is easy to replace and allows the end-user to swap the sensor on-site without having to calibrate the unit or remove it from its mount. We recommend sensors with field replaceable tips for the following reasons:
