Rain Gauge (RG-T)

The FTS RG-T rain gauge provides extreme accuracy and long-term calibration retention for mission-critical applications.
The rugged, all-metal RG-T rain gauge is FTS' take on a simple, proven, mature technology. It has earned tremendous loyalty over several years for it's extreme accuracy, excellent calibration retention and super simple deployment that ensures success.

Extremely simple.


  • Screens in the funnel and over the base plate water outlets seal the tipping mechanism completely from insects and wind-borne material.
  • Built-in bubble levels and full 3D 360° leveling mechanism, make it quick and easy to mount the tipping bucket perfectly level on any surface (even vertically).
  • The Quick Deploy version of the RG-T (optional with the QD3 portable RAWS) employs a tool-less design that utilizes “bicycle-style” quick-release clamps.

Long-term accuracy and calibration retention.


  • The tipping mechanism is acid-etched stainless steel, resulting in extreme accuracy on every unit.
  • Jeweled (ruby) bearings mean no friction, no resistance to tipping resulting in high sensitivity to accurately capture even very small rain events.
  • The jeweled bearings also prevent the mechanism from wearing out over time, resulting in long-term calibration retention.
  • The base and support posts are precision cast as a single structure, providing maximum vibration resistance. False measurements from wind are eliminated, ensuring long-term repeatable accuracy.
  • Quick-release clamps eliminate retaining screws that can rust and adversely affect accuracy.

Unmatched durability.


  • All-metal construction provides rugged durability.
  • Cable sheathed in braided stainless steel, to protect it from animal damage.
  • Cable terminates in a waterproof, military-style bayonet connector for use with Axiom dataloggers (optionally available without military connector for use with other dataloggers).
