GF900 Handheld far infrared meter reader for meter reading

Front view of the white IR meter reader

GF900 Handheld Far Infrared Meter Reader is independent developed by GFUVE. It is a new simple far infrared data acquisition terminal, embedded design, low power consumption, English operating system, high speed and long distance of meter reading, It provides a simple and reliable meter reading solution for power system.



  • Shock: circuit board components glue reinforcement; Liquid crystal soft rubber pad around Cun protection.
  • Prevent slippery: sideways tooth type to the rear of the silica gel handle and the noose form double prevent slippery protection.
  • Resistance to cast: the use of advanced nano lens, add the stem of the thick crust, slippery lock button battery cover, machine 1.5 m fall without damage.
  • Anti-interference: special circuit processing can effectively resist battery interference, to ensure that the data security.
  • Waterproof: high precision mould making, fully enclosed shell design, effectively prevent the rain water invasion, ensure the safety of the outdoor rain weather use.
  • Advanced power source design: machine use rechargeable batteries, also can use alkaline batteries, battery capacity than ordinary meter reading machine high three times.
