Hand Held Hazardous Area, Intrinsically Safe Dewpoint Meter

The Model SADPmini-Ex Automatic Dewpoint Hygrometer is a popular global choice for measureing the Dewpoint (moisture content) in gases and dry compressed air, it is also perfect for mobile analysis in Hazardous Areas.

  • Ultra Compact – Ultra Portable – Ultra Functional
  • Easy to Use – The Popular Global Choice

The SADPmini-Ex has been specifically designed to be Intrinsically Safe in hazardous environments and because of this it can be used in a wide range of applications including natural gas production, petrochemical production
and explosive gases.

This robust, ergonomically designed housing incorporates the moisture sensor, signal conditioning circuitry, memory management, 128 x 64 dot graphics display, 5 key membrane keyboard plus on-board rechargeable lithium-ion battery.

This self contained digital unit is user friendly and eliminates the problems experienced by operators and technicians with the bulky size, weight and even analogue readouts associated with the previous generation of traditional dewpoint meters.
