Dew Point Calibration

Dew point sensors need frequent calibration to ensure they are performing optimally. Our ISO 17025 accredited calibration laboratory offers calibration for dew point sensors, traceable to NIST, from -148°F to 68°F (-100°C to 20°C).

To make the process of re-calibration as simple and convenient as possible, we offer two options:

Exchange Service
As noted in the table below, we offer a very convenient, low-cost, low downtime sensor exchange program. Using this unique service is undoubtedly the quickest and most efficient method of maintaining calibration and one that will avoid any instrument downtime. HLI will send you a freshly calibrated sensor and you simply return your old sensor to us within 21 days.

Return Service
With Return service, you can choose to return your dew-point instrument or sensor to us at any time and we will calibrate the instrument or the sensor for you. For a small additional cost, we will also provide reading before and after calibration if requested at the time of order.

Our Contracts department will help ensure the process goes smoothly. Please contact us to get started.
