Analytical Industries Trace Oxygen Analyzer

A wall mounted oxygen analyzer in a NEMA enclosure, suitable for indoor or outdoor. This single channel oxygen meter can be used with flow-through O2 cells for in-line gas analysis in safe as well as hazardous areas where ATEX approval is needed. The low detection limit of 0.05ppm offers ultra-low oxygen measurement down to a range of 0 to 10 ppm. Ideal for clean gas applications and when used with the XLT oxygen sensor type it allows measurement in pure carbon dioxide. The Analytical Industries long-life oxygen sensors are maintenance-free sealed electrochemical cells that don’t need top up of electrolyte and can be exchanged in few minutes.

GPR-1500 N (ATEX)

General-purpose or hazardous area trace oxygen analyzer with four measurement ranges from 0 to 10 ppm, up to 0-1%. The analyzer consists of a control unit with HMI and an easily accessible sensor housing all contained within a NEMA enclosure suitable for indoor or outdoor mounting. This unit is loop-powered (18-28 V DC) and provides a 4-20 mA output signal. All gas wetted parts are stainless steel, the XLT sensor can be supplied as an option.

GPR-1500 A

This unit is supplied with all of the above features, plus two user-configurable alarms and the ability to be mainspowered. For safe area use only.
