SmartReader 2
4-channel relative humidity & temperature data logger  Cost: $799.00
The SmartReader 2 data logger has a built-in temperature sensor, a plug-in relative humidity sensor and is equipped with two extra channels to connect either ACR's temperature/RH probe or thermistor probes. The RH plug-in sensor is field replaceable so you can always be assured of continuous recording. The SmartReader 2 is excellent for monitoring air quality conditions.

Accessories
ACR EH-020A Temperature & RH Probe
ACR ET Series Temperature Probes |
No. of Channels
| Inputs: Four (one for internal temperature sensor, one for internal RH sensor, one for optional external RH, and one for optional external temperature or resistance) |
RH Sensor
| Sensor Type: Capacitive thin polymer film |
Response Time
| Adequate ventilation increases the response time which is approximately 5 minutes in still air |
Environmental Conditions
| Like 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 (strong acids, SO2, H2SO4, CI2, HCl, H2S, etc.), and strong bases (compounds with PH greater than 7). Dust settling on the sensor surface will not affect sensor performance except possibly to decrease the speed of response. |
