Can this recorder be outfitted to measure humidity in addition to temperature? If yes, what probe is recommended and how do you program the device?

Asked by: Yonas
Hi Yonas, The RD9906 accepts TC, RTD, and voltage signals. Please forward request to TEMP@OMEGA.COM for assistance selecting humidity sensor for your application. Best regards OMEGA

Can temp resolution be set to 0.01C? Our current system from Yokogawa has minimum resolution of 0.1C which is not fine enough.

Asked by: Markiebaby
Thank you for the inquiry. Resolution is limited to 0.1 for temperature inputs. Exception is 1 degree for platinum and tungsten TC's. Best regards OMEGA

what are the temperature ranges it reads?

Asked by: Miguel_cali
Thank you for the inquiry. Manual page 96 of the manual provides the available sensor types and ranges. Best regards OMEGA
