Frequently Asked Questions for SRP2

For SmartReader 2:

RH: Accuracy is ±4% from 10 to 90% and a temperature range of -20°C to 40°C ( -4°F to 104°F)

Temperature:  Accuracy is 0.6°C at 25°C (1.1°F at 77°F)

For SmartReader Plus 2:

RH: Accuracy is ±3% from 10 to 90% and a temperature range of -20°C to 40°C ( -4°F to 104°F)

Temperature: Accuracy is 0.23°C at 25°C (0.42°F at 77°F)

Yes. It comes with one internal RH sensor and one internal onboard temperature sensor built-in. Therefore, wherever you place the logger it will record the temperature and RH value. If you want to record the temperature and RH of a second room, you will require the EH-020A probe (which is the external temperature and RH probe). The part number for this optional probe is: 01-0040.

No. It is an optional accessory, ordered separately.

The EH-020A comes with a cable of 90 cm (3 feet).

Yes. The maximum recommended length is 100 feet of four-wire 22-gauge stranded conductor with a shield.

Organic solvents typically 1,000 to 10,000 ppm

Corrosive agents (strong acids S02, H2S04, C12, HC1, H2S etc.) typically 1 to 10 ppm

Weak acids typically 100 to 1,000 ppm

Bases typically 10,000 to 100,000 ppm

Once a year (when used under normal operating conditions).

Yes. When we calibrate the loggers we issue you a calibration certificate for the RH sensor (which is NIST traceable).

Temperature NIST traceable calibration is available at an additional charge.
