The RGTB‑6™ tipping bucket rain gauge with standard funnel provides measurement accuracy in low- and medium-rate precipitation conditions.
RGTB‑6 is made by our friends in Austraila, Hyquestion Solutions, a leading manufacturer of rain gauges offering exceptional value and performance. (This rain gauge was selected after emerging as the leader in Dyacon’s field testing for serviceability, insect protection, construction simplicity, debris screen construction, price, and manufacturing quality.)
RGTB‑6 utilizes a standard funnel catch mechanism that is suitable for low and medium precipitation rates. It employs dual reed switches for switch redundancy and for connecting parallel equipment.
- 200 mm orifice
- Tipping bucket mechanism
- Integrated leaf filter
- Machined outlet
- Easy to service
- Dual reed switches
- Varistor protection
- Encapsulated electronics
- Discharge collection ports
- Powder coated aluminum
- Debris screens
RGTB‑6™ cast aluminum funnel is mounted to an aluminum cylinder. All aluminum is powder coated.
The cylinder is mounted to the base using keyhole slots. The cylinder can be removed without fully removing the screws, minimizing the potential for lost screws while servicing equipment.
The ASA injection-molded tipping bucket is Teflon impregnated with drip-discharge geometry. The based is the same that it is used for more expensive gauges, including the sapphire bearings and dual reed switches.
The injection-molded base is made of UV-resistant ABS, which is field proven in cold and desert conditions beyond 10 years.
Each bucket tip momentarily closes a reed switch, indicating one incremental step of the gauge resolution.
Dyacon replaces the standard Hyquest Solutions cable with an outdoor-rated, jacketed cable.
The reed switches, varistors, and connector are encapsulated in pliable RTV to prevent cracking from handling and temperature fatigue.
RGTB‑6™ includes an integrated bubble level. Three-point mounting holes can be mounted to any flat surface.
A pole mount, a bird guard, and calibration devices are available.
