Vintage Wallac Thermo-Anemometer Type GGA23S

This wonderful looking scientific instrument is a Vintage Wallac Thermo-Anemometer Type GGA23S. Made in Finland by Wallac oy, now part of Perkin Elmer.

In good cosmetic and working condition, with a few surface scuffs and scratches commensurate with age and use. I can't guarantee its accuracy as it hasn't been calibrated for many a year.

• Type: GGA23S
  
• Serial Number: 12467
• It measures temperature in ºC and air speed in m/sec

Approximate Size:

• Length 23.2 cm
• 5.4 cm
• Width 10 cm

It requires one D cell/battery, which is not included as most couriers will no longer ship items containing batteries.
