1. Product Overview
The Induskey INK420 Weather Phenomenon Instrument is a high-precision precipitation detection device developed to international WMO (World Meteorological Organization) observation standards. Utilizing advanced laser diode technology at 780nm wavelength, it identifies all forms of rain and snow with precision exceeding traditional rain gauges. The instrument detects eight distinct precipitation types — from drizzle to hail — with auto-recognition accuracy exceeding 97% of manual observation. Designed for unattended operation in harsh outdoor environments, the INK420 is the instrument of choice for professional meteorological observation, road weather monitoring, and airport weather warning systems.
2. System Architecture
The INK420 operates as a fully integrated precipitation detection unit with the following core components:
-
780nm Laser Diode Transmitter: Directs a laser beam across the 180 × 30 mm measurement area (54 cm²).
-
Optical Receiver: Captures scattered and attenuated light signals as precipitation particles pass through the laser beam.
-
High-Speed Signal Processor: Analyzes particle diameter, velocity, and optical properties to classify each particle into one of eight recognized precipitation types.
-
Heating Module: Integrated auto-heating system (50W/100W) for harsh outdoor environments to prevent ice formation on optical surfaces.
-
EMC Protection Unit: EN61000-4-2/4/5/6 compliant with integrated power and signal surge protection.
-
Output Interface: Standardized codes compliant with WMO 4688/4677 (SYNOP), 4678 (METAR), and NWS code tables for seamless international meteorological integration.
-
Corrosion-Resistant Enclosure: Aluminum alloy housing with IP65 (enclosure) / IP67 (sensor seal) protection.
