start logging delay: you can specify time & date to start logging 1 year in advance with 1 minute resolution
start on alarm: yes
software alarms: high and low alarms can be specified in the software
pc connection: with separate USB interface cable
dimensions: 17.35 x 5.89mm
weight: 5g
housing material: 305 stainless steel
protection class: due to the vent required to allow humidity measurement, this device is not considered waterproof and care should be taken to avoid moisture ingress
environmental considerations: like all relative humidity sensors, when exposed to contaminants and/or conditions toward the limits of the safe operating range, accuracy degradation can result. For maximum long-term stability, the sensor should not be exposed or subjected to organic solvents, corrosive agents (e.g., strong acids, SO2, H2SO4, CI2, HCL,H2S) and strong bases (i.e., compounds with a pH greater than 7). Dust settling on the filter surface does not affect the sensor performance except to possibly decrease the speed of response.
