SmartReader Plus 2

Four-Channel Temperature and Relative Humidity Data

Logger

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

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 up to two ther-

mistor probes.

PRODUCT SPECIFICATIONS

No. of Channels:

Four - One for ambient temperature

- One for relative humidity (internal sensor)

- One for relative humidity (external sensor)

- One for temperature, resistance or switch

status

Relative Humidity Sensor:

Capacitive thin polymer film

Range:

0 to 95% RH (non-condensing)

Accuracy:

+/- 3% RH from 10 to 90% RH (-20 to 40ºC [-4 to 104ºF])

Resolution:

Better than 0.04% between 25 and 60% RH at 25ºC (77ºF)

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, SO

2SO4, Cl2, HCl, H2S, etc.) and strong bases (com-

pounds with PH greater than 7). Dust settling on the

sensor surface will not affect sensor performance except

possibly to decrease the speed of response.
