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.

SmartReader 2 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

Clock Accuracy

+/- 2 seconds per day

Memory Size

32 KB (32,767 readings)

Sampling Methods

1. Continuous (First-in, First-out)
2. Stop when full (Fill then stop)

Sampling Rates

User selectable rates from 8 seconds to once every 5 days

Operating Limits

-40 to 70°C (-40 to 158°F) and 0 to 95% relative Humidity

Resolution

8-bit (1 part in 256)

Relative Humidity Sensor

Capacitive thin polymer film

Range

0 to 95% RH (non-condensing)

Accuracy

+/- 4% RH from 10 to 90% RH (-20 to 40°C [-4 to 104°F])

Resolution

Better than 0.4% between 25 and 60% RH at 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, 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

Response Time

Adequate ventilation increases the response time which is approximately 5 minutes in still air

External Connector

Removable screw-type terminal strip with common (-) connection

Power Source

Battery

3.6 volt Lithium, 1 Amp-Hour

Power Consumption

5 to 10 microamps (continuous)

Battery Life

10 Years under normal use

Case Material

Noryl plastic

Weight

110g (3.75oz)

Mounting

Magnetic backing and locking eyelet

Internal Temperature Sensor

Type

NTC thermistor (10,000 ohms @ 25°C [77°F])

Range

-40 to 70°C (-40 to 158°F)

Accuracy

+/- 0.2ºC over the range: 0 to 70ºC (+/- 0.3ºF over the range: 32 to 158ºF)

Resolution

0.4ºC (0.7ºF) @ 25ºC; better than 1ºC (1.8ºF) between -25 and 70°C (-13º and 158ºF); better than 2.0ºC (3.6°F) between -40 and -25°C (-40ºF and -13ºF)
