Temperature - Hobo pendant temperature logger

Parameter to be measured:

Temperature

Method:

Using self-recording temperature sensors it is possible to measure the temperature continuousely. The loggers can be positioned in different heights. The result is a sample of tempareature dates and the connected calendar dates.

Equipment:

The HOBO Pendant Temperature Data Logger/ Doc # 9531-D, MAN-UA-001/ Onset Computer Corporation is a waterproof, one-channel logger with 10-bit resolution nd can record up to approximately 6,500 (8K model) or 52,000 (64K model) measurements or internal logger events. The logger uses a coupler and optical base station with USB interface for launching and data readout by a computer.

Measurement range: -20°C to 70°C (-4° to 158°F)

Accuracy: +/- 0.47°C at 25°C (+/-0.85°F at 77°F)

Resolution: Temperature: 0.10°C at 25°C (0.18°F at 77°F)

Drift: Less than 0.1°C/year (0.2°F/year)

Response time: Airflow of 2m/s (4.4 mph): 10 minutes, typical to 90%; Water: 5 minutes, typical to 90%

Time accuracy: +/- 1 minute per month at 25°C (77°F)

Weight: 18 g

Dimensions: 58 x 33 x 23 mm (2.3 x 1.3 x 0.9 inches)

Advantages:

Continous measurement; Usage is easy; Position and number of loggers at the location is optional

Disadvantages:

If there are several loggers placed on in location and they are connected by a bar, it influences the measurement results. If there is snow, the bar may push on melting around the loggers because of water runnning down the bar.
