Important Notice

This instrument provides measurement readings to its user, and serves as a tool by which valuable data can be gathered. The information provided by the instrument may assist the user in eliminating potential hazards caused by his process; however, it is essential that all personnel involved in the use of the instrument or its interface, with the process being measured, be properly trained in the process itself, as well as all instrumentation related to it.

The safety of personnel is ultimately the responsibility of those who control process conditions. While this instrument may be able to provide early warning of imminent danger, it has no control over process conditions, and it can be misused. In particular, any alarm or control systems installed must be tested and understood, both as to how they operate and as to how they can be defeated. Any safeguards required such as locks, labels, or redundancy, must be provided by the user or specifically requested of Teledyne at the time the order is placed.

Therefore, the purchaser must be aware of the hazardous process conditions. The purchaser is responsible for the training of personnel, for providing hazard warning methods and instrumentation per the appropriate standards, and for ensuring that hazard warning devices and instrumentation are maintained and operated properly.

Teledyne Analytical Instruments, the manufacturer of this instrument, cannot accept responsibility for conditions beyond its knowledge and control. No statement expressed or implied by this document or any information disseminated by the manufacturer or its agents, is to be construed as a warranty of adequate safety control under the user’s process conditions.

Handheld Hydrogen Leak Detector Introduction

Introduction

1.1 Overview

The Model 2240 Hydrogen Analyzer is a handheld portable leak detector for sensing hydrogen gas in air. It employs two sensing elements on the same semiconductor die and can detect hydrogen leaks as low as 15 parts per million (ppm). It will not saturate or be destroyed when detecting hydrogen concentration up to 100%. It is battery powered and will operate for over 10 hours on a single charge. The included battery charger will recharge the internal lithium-ion battery in 4 hours.

As the operator moves a hydrogen probe over the area of interest, it senses the presence of hydrogen. Indicators in the probe tip alert the user to the presence of hydrogen and the concentration is displayed on the control unit display. The probe attaches to the controller with an extendable coiled cord that allows up to 47 inches of reach from the Controller. The thin probe and flexible cable allow sensing in areas inaccessible to most other tools.

1.2 Typical Applications

The Model 2240 analyzer is a versatile, lightweight instrument that can be brought to a process area for analysis. Typical applications for the analyzer include:

• Leak checking process lines for H

• Analyzing the concentration of H

• H

• Specific gas mixer and process control applications

• Semiconductor manufacturing

• Hydrogen process control

safety monitoring

in air

in an air stream

• Quality assurance
