SmartReader Plus 2 Relative Humidity Data Logger
|
 |
SmartReader Plus 2
SmartReader Plus 2 is a self-contained data logger that is able to record both 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, simply attach an external temperature or temperature/RH probe.

Four Channel RH and Temperature Data Logger
|
|
SmartReader Plus 2
|
|
Range:
|
0 to 95% (non-condensing) |
|
Resolution:
|
Better than 0.04% between 25 & 60% RH at 25° C (77° F) |
|
Accuracy:
|
+/-3% RH from 10 to 90% (-20° to 40° C [-4° to 104° F]) |
|
Memory Size:
|
128 KB |
|
No. of Channels:
|
Four. (One for the internal temperature sensor, one for the internal RH sensor, one for optional external RH and one for optional external temperature or resistance) |
|
Relative Humidity Sensor:
|
Capacitive thin polymer film |
|
Response Time:
|
Adequate ventilation reduces 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 (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. For information on the RH sensor’s tolerance to chemicals, see Accessories section under Relative Humidity |
