SmartReader 2 Data Logger
Manufacturer : ACR Systems

ACR Four Channel Logger: Temperature, Humidity with options for external Temperature and Humidity

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 sensor is field replaceable so you can always be assured of continuous recording. The SmartReader 2 is excellent for monitoring “air quality” conditions.

Required with Temperature Data Logger
>> TrendReader 2 Software

Required for Ethernet Connectivity
>> TrendReader 2 Software with USB Cable Kit (#TR2-USB)

 

Temperature and RH Logger Features

  • Can Store about 32,000 Readings
  • 10 Year Battery Life
  • Great For HVAC system testing and balancing

distance 5”


 

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)
Range -40 to 70°C (-40 to 158°F)
Resolution 0.4°C (0.7°F) at 25°C (77°F); better than 1 °C (1.8°F) between -25°C and 70°C (-13°F and 158°F); better than 2.0°C (3.6°F) between -40°C and -25°C (-40°F and -13°F)


 

Internal Humidity Sensor
Type Capacitive thin polymer film
Range 0 to 95% RH (non-condensing)
Acccuracy ± 4% RH from 10 to 90% RH (-20 to 40°C [-4 to 104°F])
Resolution Better than 0.4% RH between 25 and 60% RH @ 25°C (77°F)
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, 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.
