Description: | The RH sensor inside the humidified nephelometer began to slowly decline in value in the
upper RH range beginning in early 2004 and becoming more noticable poor on 20041117. The
sensor currently reaches a high RH value of about 60% when the actual RH is closer to 80%.
The sensor was replaced in the Spring of 2005, but the problem remained. Effective
1/1/2004, this sensor is not used to calculate scientific data and is therefore essentially
abandoned in the field. An end-date of 20050501 is being used as a placeholder. |
