Hi, I’m Todd with BlastOne. Today, I’m going to walk you through the standard steps of getting started with your GX4 Monitor.
The purpose of the GX4 is to monitor dangerous gases in the air. We offer three types of sensors: CO2, hydrogen sulfide, and oxygen sensors. To remove a sensor, press the small button on the bottom, pull it out, and to reinsert, push the tabs in and secure it. If the sensor is not correctly in place, a warning will appear and after 30 seconds, an alarm will sound similar to that for dangerous levels, indicating the sensor is not making contact.
The O2 sensors come in two forms: a five parts per million for Canada and a ten parts per million for OSHA standards, which is what comes standard with the GX4. The hydrogen sulfide sensor is used in critical areas like sewage treatment, water treatment, and oil refineries. Hydrogen sulfide is a heavier gas with a distinctive rotten egg smell, and it’s a desensitizer, making it dangerous as prolonged exposure lessens your ability to detect it.
We have two options for mounting:
1. **Wall Brackets**: These allow you to mount the GX4 directly to a wall.
2. **Heavy Duty Carrying Case**: This comes standard with our combo skids and is ideal for heavy-duty jobs to keep the GX4 safe. The case muffles the high-decibel alarm, so ensure it’s in a place where you can still hear it.
You can also mount the GX4 directly to the side of the Radex using the same twist-on method. The airline connects from the GX4 to the regulator and into the Radex. The GX4 is powered with a 12-volt system, connecting to battery leads that attach to a car battery. Alternatively, a 120-volt cord can plug into a wall to power and recharge the battery.
To power on the GX4, hold down the OK button until it turns on. It takes a moment to cycle through and start reading real-time data. The GX4 can also connect to a network or mobile device for remote monitoring.
Once powered on, the GX4 will give a small reading, typically 2 to 3 ppm in ambient air. Use the test button to ensure the alarm is functioning correctly. It will sound for five seconds to simulate an alarm for high sensor readings.
The air supply to the GX4 comes from the Radex. Connect your breathing air compressor to the Radex via the Chicago fitting and set the regulator to the desired level for your breathing equipment.
For calibration, we offer a gas calibration kit for the CO2 sensors, including a zero air and a 20 parts per million canister of gas. This allows you to calibrate the sensor by hooking it up to the GX4 and adjusting as needed.
