The Rainwise HM-1 Weather Station provides real-time information for monitoring and responding to emergency situations

The station works in conjunction with CAMEO/ALOHA software which enables responders to evaluate and predict plume dispersion patterns. The HM-1 was designed for rapid deployment and can be setup by one person in less than 2 minutes. The HM-1 has been engineered to combine high performance and durability at an affordable price.  

Key Features

  • Rapid deployment in under 2 minutes
  • Compact, rugged construction
  • Long range spread spectrum radios
  • Real-time display
  • CAMEO/ALOHA support
  • 5-year Warranty

The HSA-1 Sensor Assembly

The compact sensor assembly is constructed from durable polycarbonate, fiberglass and aluminum. The assembly contains a number of sensors to measure commonly required parameters, such as wind speed, wind direction, temperature, humidity and barometric pressure. In addition to the aforementioned sensors, the HSA-1 also includes a radiation detector. This helps insure personnel safety when responding to an unknown incident. A built in electronic compass makes installation quick and easy with no alignment required. The coded long range spread spectrum radio has a range of up to 7 miles (11 km) (900 MHz version). This provides the ability to monitor environmental conditions at a safe distance. The assembly can be hosed down for easy decontamination.

The RDI-1 Display & Data Logger

The RDI-1 has large bright LED displays that can be easily read in low ambient light and have wide viewing angles. The RDI-1 tracks minimum and maximum values for each parameter. The data logger is compatible with the CAMEO/ALOHA plume modeling software package. The data logger has a battery backed up, real-time clock and 32K of non-volatile RAM which means data will not be lost when the unit is powered down. Data is logged even while CAMEO is being used.

The logged data can be retrieved and viewed with a number of other third party software applications. At least one of these applications is supplied with each RDI-1. The display and data logger are housed in a tough copolymer enclosure. The display can be powered from its own internal sealed lead acid batteries, 12VDC vehicle adapter or AC battery charger. Several RDI-1’s can receive data from a single HSA-1 sensor assembly.

Transport Case & Tripod

The entire HM-1 weather station fits into a single compact transport case. The station can be deployed and be fully operational in under two minutes. No tools are required and the tripod features a unique push button locking system that is secure and easy to use. The tripod is adjustable to a fully extended wind sensor height of 10 feet. A ground anchor kit is included to secure the station when the system is deployed in extreme weather conditions.
