Review AST Scuba Rebreather Oxygen Sensor

The AST-22D Scuba Rebreather Oxygen Sensor is a crucial accessory for any closed-circuit rebreather (CCR) diver looking to ensure the safety and efficiency of their diving system. This sensor, manufactured by Analytical Systems Technology, is specifically designed to monitor the oxygen level of the diluent gas flowing into the scrubber or Absorber of the scuba rebreather.

The AST-22D comes in a compact and durable design, making it ideal for underwater exploration. The sensor utilizes an electrochemical fuel cell to measure oxygen concentrations accurately. The sensor's housing is constructed from high-quality, corrosion-resistant materials, making it perfect for the harsh underwater environment.

The sensor's operating range is from 0 to 100% oxygen concentration, making it suitable for various diving scenarios. It is designed to provide reliable and accurate measurements, with a stated accuracy of /- 0.3% O2 for readings between 21% and 100% oxygen concentration. The sensor's sensor head features a large, easy-to-read, backlit LCD display, allowing divers to check their oxygen levels quickly and easily, even in low-light conditions.

This model of the oxygen sensor is approved by various international organizations such as Divers Alert Network (DAN), National Oceanic and Atmospheric Administration (NOAA), and European Union (EU) for use in demanding rebreather diving applications.

Warning alarms, audible and visual, are built into the sensor to notify divers of low or high oxygen levels, providing an essential safety feature. An automatic calibration function allows the sensor to be easily calibrated using a built-in calibration gas or an external calibration source.

The AST-22D Scuba Rebreather Oxygen Sensor requires a low power consumption, making it perfect for extended dives. It can be powered by a single CR2450L 3V Lithium Battery that is easily accessible for replacement. When the battery reaches a low level, the sensor displays a low battery warning on the LCD screen.

The sensor comes with a flexible, kink-resistant, and heat-resistant cable, allowing divers to position the sensor in their preferred location on their rebreather. The sensor's overall weight of 125g (4.41 oz) and dimensions of 77mm x 108mm x 31mm (3.03in x 4.25in x 1.22in) make it a compact addition to any diving system.

In conclusion, the AST-22D Scuba Rebreather Oxygen Sensor is a high-performance, precise, and durable oxygen sensor that offers reliable oxygen level monitoring for CCR divers. Its ease of use, battery-powered design, and robust construction make it the go-to choice for divers who demand top-notch performance and safety in their diving equipment.

Astex AS-22D Scuba Rebreather Oxygen Sensor: A Comprehensive Analysis

The Astex AS-22D Scuba Rebreather Oxygen Sensor is a crucial component for those using closed-circuit rebreathers for underwater exploration. In this analysis, we will discuss the primary features and advantages of this sensor, along with potential drawbacks.
