HY-ALERTATM 500 HANDHELD HYDROGEN LEAK DETECTOR OPERATING MANUAL IMPORTANT NOTICES Read and understand this operating manual before installing or using the unit. Only use cables, battery pack, battery charger, and AC/DC power supply from H2scan with this unit. If this equipment is used in a manner not specified by H2scan, the protection provided by this equipment may be impaired. Hydrogen is flammable at 4% in air. Take indications seriously and be prepared to take action. In the event of detection of 4% or higher of a hydrogen gas concentration there is a high probability of a hazard to safety....

HY-ALERTATM 500 HANDHELD HYDROGEN LEAK DETECTOR OPERATING MANUAL 1 DESCRIPTION H2scan believes that protecting lives means being able to locate and find hydrogen leak as quickly as possible. With two sensing elements on the same semiconductor die, the HY-ALERTA™ 500 can detect hydrogen leaks as low as 15 ppm and will not saturate or be destroyed when detecting concentrations of hydrogen up to 100%. The flexible cable allows the sensor probe access to virtually all potential leak sources. SPECIFICATIONS Sensitivity Range: Response Time: Indication of hydrogen within seconds. Stabilization to final...

HY-ALERTATM 500 HANDHELD HYDROGEN LEAK DETECTOR OPERATING MANUAL OPERATION 3.1 STARTUP To power-up the HY-ALERTA™ 500, press and hold the ON/OFF button until the Controller LCD display indicates an operational message. Warning: Only power-up the instrument in a hydrogen-free environment. After power is on, the instrument takes about ten minutes to warm-up. During this time the LCD displays a countdown to completion and the Probe Tip LED is amber. The following operations occur: The Wide Range Sensor® reaches operating temperature. A system self-test is run. Upon successful completion of the above...

HY-ALERTATM 500 HANDHELD HYDROGEN LEAK DETECTOR OPERATING MANUAL The Probe Tip LED Indicator shows an increase or decrease in hydrogen concentration. Leak detection is accomplished by watching the Probe Tip LED and the bar graph array and moving the sensor around a potential hydrogen leak. Probe Tip Colors Solid Green Pulsing Green - Unit ready - < 15 ppm hydrogen - Decreasing H2 level Solid Amber - System startup - Steady H2 level Pulsing Red Alternating Red, Green - Increasing H2 level - Fluctuating H2 level The number of yellow LEDs lit in the Probe LED bar graph array indicates detected hydrogen...

HY-ALERTATM 500 HANDHELD HYDROGEN LEAK DETECTOR OPERATING MANUAL 4.2 HYDROGEN-FREE AREAS For the purposes of this document a hydrogen-free area is one with less than 5ppm of hydrogen in the air. It may be difficult to find a hydrogen-free area in a facility where hydrogen is used. Nearby rooms, or even the entire building, may not be hydrogen free. To check these areas reset or zero the sensor outside, away from any hydrogen tanks, pipes, or other potential sources. Walk through the facility, watching the sensor. It is surprising how far low levels of hydrogen can spread. If the sensor is zeroed...

HY-ALERTATM 500 HANDHELD HYDROGEN LEAK DETECTOR OPERATING MANUAL The hydrogen plume from a leak generally spreads in a roughly conical shape that is easily disturbed by environmental conditions. Certain conditions such as pressure, temperature, and leak size may act together to change the shape of the hydrogen plume from a cone to a laser-like beam. This makes finding a leak more difficult. If the sensor element is near (and above) the leak, the concentration will likely be higher but the leak may be difficult to locate. As hydrogen dissipates the concentration decreases. Generally, greater distances...
