XP 702

The Cosmos model XP-702S is extremely sensitively used not only by the gas but also by many other branches of industry where combustible gases or vapoures are used

It is a unique type of detector which opens up a new concept of gas leakage detection.   The XP-702S easily and quickly locates leaks in pipes and fittings where conventional methods such as soap solutions are impracticable. The sensitivity is high enough to test above ground for leaks in underground pipelines. This light and compact instrument is very convenient to use and affords considerable reduction in operator fatigue, labour time and cost

Features

  • Much more sensitive than soap solutions.
  • Sensitive enough for above ground leak test.
  • Faster and more convenient than conventional techniques.
  • Hand-held portable with automatic pump.
  • Compact and Lightweight.
  • Simple to operate.
  • Long sensor life.
  • Ruggedly constructed.

DETECTS VARIOUS GASES: It can not only detect most combustible gases and vapours (including catalyst poisoning gases such as hydrogen sulphide, methyl chloride and methyl bromide) but also the non-combustible Freon R-22.

PRINCIPLES : The detection principle is two terminal type sintered semiconductor gas sensor with very low power drain, developed by Cosmos. This new type of sensor enables very low concentrations of a variety of gases to be detected.

OPERATION: The sample is drawn from a search probe automatically and continuously by an internal extremely low power drain micropump, passed over the sensor and exhausted to atmosphere. This automatic sampling method with the small size and light weight of the instrument allows normal work operations to be carried out with one free hand.

An intermittent tone sounds and an LED lamp flashes if a gas leak is detected, and a frequency of the signals will increase as a source of the leak is approached. An LED power pilot lamp goes out when batteries require replacement. An earphone jack is provided so that an earphone can be used where noise in the area to be tested obscures the tone signal. The tone signal can be silenced with a buzzer -off switch when it is a nuisance.

PROBES: A variety of search probes are available as accessories for use in locating leaks according to locations to be tested.

 

Special Model

Model XP-702S-A - This model is furnished with sensitivity calibration for two types of gas. A changeover switch selects the desired calibration of the two. It is usually used by an industry which supplies or uses two major types of gas, for example Natural gas and manufactured gas, or natural gas and LP gas.

When ordering XP-702S-A, please specify the two types of gas for which calibration is required.
