The 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 (Relative
Humidity) sensor is temperature compensated, permitting reliable, worry-free RH readings. For remote sensing of temperature and RH, simply attach ACR’s external temperature/RH probe, or for remote temperature sensing, attach up to two of ACR's thermistor probes.

| Internal Temperature Sensor | |
|---|---|
| Type | Negative Temperature Coefficient Thermistor. 10,000 ohms @ 25°C (77°F) |
| Accuracy | ± 0.2°C, over the range of 0 to 70°C (±0.3°F over the range of 32 to 158°F) |

| Internal Humidity Sensor | |
|---|---|
| Type | Capacitive thin polymer film |
| Range | 0 to 95% RH (non-condensing) |
| Acccuracy | ± 3% RH from 10 to 90% RH (-20 to 40°C [-4 to 104°F]) |
| Resolution | Better than 0.04% RH between 25 and 60% RH @ 25°C (77°F) |
| 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, Cl2, 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. |

Fast Sampling with Battery Pack or External 120 Volt Power Supply
For sampling rates faster than once every 8 seconds, the Smart Reader Plus data loggers require 
the use of an external 120 volt power supply (#PS-201) or fast sampling battery pack (#BP-101).
The fast sampling battery pack has replaceable "AAA" batteries and 8" (20cm) cable attached, with a male stereo jack on the end. The stereo jack is plugged into the communication port on the Smart Reader Plus data logger.
The 120 Volt Power Supply is required when network length is greater than 50' , more than 3 loggers are on the network, or for sampling rates greater than 8 seconds on the SmartReader Plus Loggers.
