ACR SmartReader Plus Temperature & Humidity data loggers

Covering SmartReader Plus models 1, 10, 2, 5, 6, 8

ACR SmartReader Plus Temperature (& Humidity) data loggers

ACR SmartReader Plus data loggers are multi-channel, high quality data loggers that monitor a variety of parameters and feature a 10 year battery life. The alarm feature alerts when thresholds are transgressed, via phone or email*. These loggers are accessible remotely by modem or device server; multiple loggers can also be linked to form a network. Durability is assured with a 3-year logger warranty and 10-year battery life.

On many competitive products, if a replaceable battery comes loose or dies, you could lose the data – the lost time and effort far outweighs any price difference. The SRP range is carefully designed for ultra-low power consumption, with its a 12-bit successive approximation A-D converter. When the recording interval is set longer than 8 seconds, the readings are sampled every 8 seconds and averaged over the recording interval. This gives a much more realistic picture of what you’re measuring, compared to just taking 1 measurement each recording interval.

Software Packages (TrendReader) are purchased separately as they can support more than one device.

Faster logging, up to 25 samples per second, is supported using an external power source (USB cable or BP-101 Battery Pack option, see below).

SmartReader Plus 10

SmartReader Plus 10 is a temperature logger with four channels. Sn internal thermistor channel and three external channels specifically designed for use with RTD (Resistance Temperature Detector) temperature probes, designed to precisely measure temperature over a wider temperature range than a thermistor, without sacrificing accuracy or resolution.

Two-, three-, and four-wire RTDs may be used with the SmartReader Plus 10, however, four-wire RTDs produce the highest accuracy. RTDs with a Temperature Coefficient Resistance (TCR) of 0.00385 can be used with this data logger.

Specifications

No. of Channels:
Four (one for ambient temperature, and three for temperature with RTD probes)

RTD Type:
Any 100 or 1000 ohm Platinum RTD with a Temperature Coefficient of Resistance (TCR) of 0.00385

Temperature Range*:
-230 to 300°C (-382 to 572°F)

SmartReader Plus 2

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 ACR’s thermistor probe. 

Specifications

RH Sensor Type:
Capacitive thin polymer film

RH Sensor Range:
0 to 95% RH (non-condensing)

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

RH Sensor Resolution:
Better than 0.04% RH 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 (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.
