Oldham GD10PE

Teledyne Oldham GD10PE IR Extended Point Gas Detector

The GD10PE is designed for critical applications involving large volumes of air with high velocity. In places where you need fast reliable detection of low gas concentrations. GD10PE is in a class of its own.

Key Features

  • Solid-state IR sources (SimSourceTM) for superior long term performance compared to filament lamps
  • No recalibration, monitors and accounts for all changes in optical path thanks to true dual path, double compensation optical design
  • Selectable response rate
  • Dual-layer weather protector (No mesh, gauze, hydrophobic filters or sinters = No delay, no failure on demand)
  • Early dirty optics warning for improved preventative maintenance

Please note - Product designs and specifications are subject to change without notice. The user is responsible for determining the suitability of this product.

The versatile GD10PE is suitable for monitoring, among others, the HVAC air intakes of living quarters, temporary refuges and local equipment rooms. In addition the ventilation air and combustion air intakes of gas turbines can be monitored along with the ventilation air extract duct, the only location where you can guarantee to detect a gas leak on a turbine package. With a measuring range of 0-20% LEL the GD10PE is 5 times more sensitive than standard point detectors.

The GD10 range of infrared gas detectors differ from all other models, because they utilise silicon based solid-state infrared sources. The complete optomechanical design and construction is so stable that an ultra-fast speed of response can be achieved whilst providing unparalleled service life and detector stability, thus saving on maintenance and service costs. An industry-standard HART® interface is used for configuration of the levels as well as access to maintenance data. Features and benefits include an independently heated mirror and lens for high-performance detection in rough environmental conditions and guaranteed continuous operations at 85°C which make this instrument suitable for turbine ventilation extract ducts.
