SmartReader 2 is a data logger for easy and reliable tracking of "air quality" conditions. It has a built-in temperature sensor and a plug-in Relative Humidity sensor. The Relative Humidity sensor is field replaceable so you can always be assured of accurate readings.

|
|
SmartReader 2
|

|
| Memory Size:
|
32 KB.
|
| Accessories:
|
ACR EH-020A Temperature & RH Probe
ACR ET Series Temperature Probe.
|
| 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 (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. For more information on the RH sensor .s tolerance to chemicals, see Accessories section under Relative Humidity.

PC to SmartReader Communications
To setup, download or view realtime information from an ACR SmartReader Data Logger, all that is required is an ACR IC-101 Interface Cable. Connection is simple. Plug the IC-101 connector into your PC's serial port and the stereo cable into the ACR Data Logger. The IC-101 cable is included with the ACR TrendReader Interface Package. No tools, interface cards or docking stations required. You can setup, download or view realtime information from up to 8 loggers at once, locally or over a modem.

|
Fast and Easy Logger Setup
Since TrendReader® comes complete with built-in menus for Sample Rate, Start Delay, Equations and more, setup is fast and easy. In addition, equations are already included for all ACR accessories so users need only select the appropriate equation from the menu. Realtime readings are displayed in the Setup window, allowing you to ensure that your logger's setup is correct before placing it in the field. |
 |
One-Touch Table View
With ACR's TrendReader® Software, logged data can be viewed in Table format to permit detailed analysis of logged data. Multiple channels of data can be displayed at once with each reading displaying the time and date. You can even select portions of, or all the table information and paste it into your favorite Windows® presentation or word processing program.
|
 |
Presentation Quality Graphs
TrendReader® allows you to present logged data the way you want. Multiple logged data sets can be displayed and compounded to create new graphs. For added presentation power, TrendReader® lets you add comments, change graph colors, zoom in on specific portions of data, display your data using custom engineering units and print to any Windows® compatible printer with ease. TrendReader® even lets you copy/paste your graphs directly into your case reports. If you prefer to use Excel,® Lotus® or other popular spreadsheet programs, data can be exported into ASCII and CSV formats.
