 Gill Instruments: HS-50
Key Features:
- Maintenance Free
- Robust Construction
- 50Hz Data Rate
- Speed of Sound and Sonic Temp Outputs
- Custom Calibrated
- Analogue Outputs
The Solent Research R3-50 is a cost effective solution for projects requiring the benefit of Gill's proven experience in the production of ultrasonic anemometers for all weather applications. Robust and easy to use, the R3-50 employs the same software as the popular R3 range of sensors but with a data rate of 50 Hz.
If required the unit can be supplied with the optional Sensor Input Unit (for analogue inputs) and Power Supply (including analogue outputs).
Based on the highly successful range of Solent Research Anemometers, the R3-50 is ideal for users undertaking research with eddies at high mast levels.
Having identical output formats to the R3, the R3-50 is particularly suited to applications where a complete wind profile is required, with an R3 or HS positioned near the ground and the R3-50 positioned at a higher level.
Gill research grade units are individually custom calibrated and supplied with a certificate of calibration. All of our test equipment has been designed specifically to test and calibrate our range or ultrasonic sensors and is traceable to national standards. A number of orderable options are available including:
- Power supply (PCIA)
- Travelling case
- Analogue and PRT inputs via Signal Interface Unit (SIU)
