ICT International Pluviometers and Rain Gauges

The stainless steel rain gauge measures rainfall amount and intensity. Two models are available: SRG0 is a standard tipping bucket rain gauge with 5m cable to connect to a data logger; the SRG1 is a pluviometer with an internal event data logger. The SRG1 is ideal for remote and long term monitoring of rain events.

• Constructed entirely of stainless steel.
• Rain enters the gauge through an 20cm orifice, protected by distortion preventing aluminum ring.
• Collected water passes through the debris-filtering screen and is funneled into one of two tipping buckets inside the gauge.
• When a given amount of water collects, the bucket tips. (Tip of 0.2mm is standard).
• Tipping causes magnet to pass over proximity switch, closing it momentarily.
• Second bucket positions under funnel for filling.
• After rain is measured, it exits through drain tubes with screen covered holes in the base of the gauge.
• Designed for many years of accurate, trouble free operation.
• Stainless steel outer housing.
• Built in level indicator and pre-drilled feet.

ML1 Mini Log

The ML1 is an ideal one channel data logger for recording rain fall events from tipping bucket rain gauges, pulses from water meters, or other similar applications. Very low power consumption and a robust aluminium waterproof housing allow this logger to be deployed in the field for up to ten years in remote locations.
Events are stored in the memory, which can then be downloaded to a PDA, laptop or desktop computer, using either WinComLog to download and graph data, or HyperTerminal to download data for use in Excel. An RS-232 serial port allows the direct connection of the ML1 to a computer on site.
