Climate-measuring instrument with double display MA 2296 1K

Climate-measuring instrument for room monitoring with display of temperature and humidity side-by-side. Suitable for computer-based and central data-acquisition, e.g. in climatic test chambers, climatic rooms, museums, galleries, computer rooms, clean rooms, and for judging on historical buildings protected and in need for renovation.

By means of the output sockets up to 100 instruments can be networked. This can be done with special distribution boxes. They can be installed in a distance of 1 km from each other and can be arranged in a line or radially. Power supply is provided centrally by 1 PSU or locally by a seperate PSU for each instrument.

Using special software, limiting values for temperature and humidity can be specified up to choice for each instrument.

Humidity meas. circuit: 

Measuring range:                        5 to 98% r.H. (total range 0 to 100%)
Sensor:                                       capacitive thin-film sensor
Nominal temperature:                 25°C ±3°C
Accuracy:                                    ±2% r.H.
Reproducability:                        < 1% r.H.
Operating pressure:                  0,04 to 20 bar
Response time T90:                  approx. 8 s (without sensor filter)
Temperature meas. circuit:
Sensor:                                       NTC type N (10 k at 25°C)
Operation range:                      –20 to +60°C
Accuracy:                                 –30 to 0°C:     ± 0,4°C
                                       0 to +70°C:     ± 0,1°C
Reproducability:                      0,1°C
