With its air2guide product range for air-handling technology, this company also offers measuring solutions for cleanrooms. For positive and negative pressure control, the Model A2G-05 differential pressure gage with a minimal insertion depth (42 mm) has been developed. The instrument covers pressure ranges from 0–50 Pa up to 0 to 2,500 Pa, as well as –25 to 25 Pa and –1,500 to 1,500 Pa. The low depth dimension makes it especially suitable for recessed installations in cleanroom walls and doors. — Wika Alexander Wiegand SE & Co. KG, Klingenberg, Germany
