§
3.1
Calibration
The Model TB7 Tipping Bucket Rain Gauge is batch calibrated. The batch calibration process guarantees that each rain
gauge supplied will work within the range of accuracy specified by HyQuest Solutions, namely “0 to 200 mm per hour: +/-
5 % for 0.2mm, 0.01” and 0.5mm buckets, 200-500 mm per hour: Better than +/-8%” for 0.5mm bucket only. The batch
calibration process is detailed below:
§
Buretting:
Each side of the tipping bucket is balanced and buretted to the practical volume applicable to the resolution of the
gauge (i.e. 0.2mm or 0.5mm or 0.01"). The buretting is carried out with NATA calibrated and certified equipment.
§
Initial Calibration:
The initial production run of 50 rain gauges are all buretted, as described in Item i) above and calibrated on our
TB340A Laboratory calibrator, over a range of intensities (50mm/hr to 500mm/hr)
§
Ongoing Calibration:
From every batch of 50 units thereafter, one gauge will be randomly selected and fully calibrated as per Item ii)
above, to ensure the specified accuracy and repeatability are maintained.
On request a full calibration can be undertaken at additional cost.
Please contact either HyQuest Solutions Pty Ltd or our local distributor for further information.
