SmartReader Plus 2 is a self-contained data logger that can monitor and record temperature and relative humidity - right out of the box. The on-board RH sensor is temperature compensated, permitting reliable, worry-free RH readings. For remote sensing of temperature and RH, simply attach ACR's temperature/RH probe, or for remote temperature sensing, attach ACR's thermistor probe.

• Equipped with one internal ambient temperature channel and one internal RH channel
• External channel can accept one remote Temp & RH probe
• Network up to 10 various SRP data loggers
• Can be calibrated to NIST standards
RH Sensor TypeCapacitive thin polymer film
RH Sensor Range0% - 95% RH, Non-condensing
RH Sensor Accuracy± 3% RH from 10% - 90% RH from -20°C - 40ºC (-4°F - 104ºF)
RH Sensor ResolutionBetter than 0.04% RH between 25% - 60% RH at 25ºC (77ºF)
Response TimeAdequate ventilation increases the response time which is approximately 5 min in still air
Environmental ConditionsLike all relative humidity sensors, when exposed to contaminants and/or extreme environmental conditions accuracy degradation could result. For maximum long-term stability, sensor should not be exposed or subjected to organic solvents, corrosive agents (acids, SO2, H2SO4, Cl2, HCl, H2S, etc.), and strong bases (compounds with pH > 7). Dust settling on the sensor surface will not affect sensor performance except possibly to decrease the speed of response.
