Humidity Transmitter NIST Traceable Certificate of Calibration – Application Note


NON-ROOM UNITS

BAPI’s standard product accuracy for Duct and Outside Air Humidity units is either ±2.0% or ±3.0% relative humidity. BAPI can provide a NIST Traceable Certificate of Calibration for each transmitter assembly as shown in the figure below. Each certified sensor/ transmitter pair has a unique certification and BAPI retains certification data for future reference.

Each sensor is placed into a precision humidity chamber that can hold a relative humidity condition to within ±0.5%RH. The humidity transmitter’s output is recorded at each humidity certification point. BAPI normally tests at 25%, 50% and 75% relative humidity at 23°C (73°F). BAPI’s humidity chamber has temperature test limits of 10 to 60°C (50 to 140°F) and humidity test limits of 15%RH to 85%RH. BAPI will test at any relative humidity and temperature that you specify within the humidity chamber’s capability.

If you require the humidity reading to be certified at more than one temperature, please contact your BAPI representative for pricing. Please allow additional lead time when ordering certified units. If you have any questions about the certification documents, please contact your BAPI representative.

ROOM UNITS

BAPI’s standard product accuracy for Humidity Room Sensors is ±2.0%. BAPI can provide a NIST Traceable Certificate of Calibration for each sensor assembly as shown in the figure below. Each certified sensor has a unique certification and BAPI retains certification data for future reference.

Each sensor is placed into a precision humidity chamber that can hold a relative humidity condition to within ±0.5%RH. The humidity sensors output is recorded at each humidity certification point. BAPI normally tests at 25%, 50% and 75% relative humidity at 25°C (77°F). BAPI’s humidity chamber has temperature test limits of 10 to 60°C (50 to 140°F) and humidity test limits of 15%RH to 85%RH. BAPI will test at any relative humidity and temperature that you specify within the sensor’s operating range and humidity chamber’s capability.

If you require the humidity reading to be certified at more than one temperature, please contact your BAPI representative for pricing. Please allow additional lead time when ordering certified units. If you have any questions about the certification documents, please contact your BAPI representative.
