3. Product Overview

The FD-90A-O2 is a robust and accurate oxygen detector featuring an electrochemical cell sensor and an integrated pump for sampling. It provides real-time oxygen concentration readings and alerts users to unsafe levels through adjustable audio, visual, and vibration alarms.

3.1 Components

This image displays the main components of the system: the compact yellow and black oxygen detector unit on the left, and the elongated yellow sampling pump with its metal probe on the right. Both units feature digital displays.

This diagram highlights various features of the oxygen detector, including the large and clear display with backlight showing temperature, concentration, and battery, RED LED and vibration alarms, Micro-USB charging port, anti-slip grip, buzzer alarm, high capacity Li-Ion battery (3.7V 2000mAh), and the electrochemical sensor.

This image provides a detailed view of the sampling pump, pointing out its stainless steel probe with screw-on air-intake, high-resolution LCD displaying time, temperature, pump power, and battery level, USB recharge port for the Li-ion battery, rugged ABS construction, and the air-output port.

3.2 Features

• Accurate O2 Detection: 0-30.0% range with 0.1% resolution, USA NIST traceability calibrated.
• Integrated Pump: 0.5 LPM (500cc/min) sampling pump for remote detection.
• Electrochemical Sensor: High accuracy (≤±5% F.S.) and fast response time (T<30s).
• Multiple Alarms: Adjustable audio, visual (LED), and vibration alarms.
• Durable Design: Shock-proof, water-proof, dust-proof, and explosion-proof with a convenient belt clip.
• USB Rechargeable: Built-in high-capacity Li-Ion battery (3.7V 2000mAh).
• Data Logging: Alarm digital time stamp and logging capabilities.

4. Setup

4.1 Initial Charging

Before first use, fully charge the device. Connect the provided USB charging cable to the detector's Micro-USB port and a compatible USB power source. The battery indicator on the display will show charging status.

4.2 Attaching the Pump and Probe

The sampling pump and probe are essential for remote sampling. Follow these steps to connect them:

This image illustrates the connection process: the detector is on the left, the pump and probe on the right. A clear tube connects the detector's inlet (via a calibration cap) to the pump's air-output port. This setup allows for sampling and extending tubing up to 60 feet (20 meters).

1. Ensure both the detector and pump are powered off.
2. Connect one end of the sampling tube to the air-output port of the pump.
3. Attach the other end of the sampling tube to the calibration cap on the detector.
4. Ensure all connections are secure to prevent leaks and ensure accurate sampling.

5. Operating Instructions

5.1 Powering On/Off

• To Power On: Press and hold the power button (usually the center button) until the display illuminates and the device performs a self-test.
• To Power Off: Press and hold the power button until the device powers down.

5.2 Taking Measurements

Once powered on, the detector will begin displaying the current oxygen concentration. For remote sampling with the pump:

1. Position the probe in the area where oxygen measurement is required.
2. Turn on the sampling pump. The pump will draw air through the probe and tubing to the detector.
3. Observe the oxygen concentration reading on the detector's display.
4. If an alarm sounds, evacuate the area immediately and follow your facility's safety protocols.

5.3 Alarm Functions

The device features adjustable alarm thresholds for low and high oxygen levels. When oxygen concentration falls outside the safe range, the device will activate:

• Audible Alarm: A loud beeping sound.
• Visual Alarm: Flashing RED LEDs.
• Vibration Alarm: The device will vibrate.

Refer to the device's on-screen menu for adjusting alarm set points.

6. Maintenance

6.1 Calibration

The FD-90A-O2 comes factory calibrated. However, regular calibration is crucial for maintaining accuracy and ensuring reliable readings. It is recommended to calibrate the device every 6-12 months, or as required by your industry standards. Use USA NIST traceable calibration gas for best results.

The device offers zero and span calibration options, accessible through the menu. Consult the on-screen prompts for detailed calibration steps.

6.2 Cleaning

Clean the exterior of the device with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the sensor inlet and pump intake are free from dust and debris.

6.3 Battery Care

The device is powered by a rechargeable Li-Ion battery. To maximize battery life:

• Avoid fully discharging the battery frequently.
• Store the device in a cool, dry place when not in use for extended periods.
• Recharge the battery periodically if stored for a long time to prevent deep discharge.
