IS UHFS-09 good for outdoor measurements? Does it measure total heat flux, i.e., conduction plus convection plus radiation?

Asked by: A_V_
Hi A_V_ Thank you for the inquiry. UHFS-09 has water proof construction for durability in wet/splashing condition. The black surface provides for heat flux due to convection and radiation sources. Best regards, Omega

If I need to calculate the total heat power through HFS-5, should I multiply the measured heat flux with sensor area (6.5cm2) or total area (9.2cm2)?

What is the maximum sampling rate for the HFS-5?

Asked by: Trevor42
Hi Trevor C Thank you for the inquiry. Sample rate would be determined by the instrumentation used. Response time of the sensor is 0.6 seconds as noted on the data sheet. Best regards OMEGA

What is the output voltage range for HFS5?

Asked by: Trevor42
Hi Daniel18 Just under 1 mv at max heat flux. You'll need a meter with micro volt level resolution. Best regards, OMEGA
