IOThrifty Blog

At IOThrifty, we work with customers from diverse industries,food processing, pharmaceuticals, HVAC, and more, who rely on accurate dew point measurements. Whether you’re monitoring moisture content in compressed air lines or ensuring environmental stability on a manufacturing floor, reliable dew point meters, dew point transmitters, and dew point sensors are essential to maintaining optimal process conditions.

A common question customers ask is whether a humidity or dew point sensor requires periodic recalibration. The answer depends on the specific accuracy requirements of the process in which the sensor is used. Most sensors will drift over time from their original specified accuracy, so periodic verification and adjustment may be required to restore them to their original accuracy specifications.
