SmartReader Plus 2 – 128 KB

SKU: 01-0113
Model: SRP-002-128K

Four channel, 12 bit, 128 KB data logger (One ambient temperature and RH channel and one external temperature and RH channel).

Product Features

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. Compativle with ACR’s TrendReader® software


Software Requirements




3 – years

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.
