Series 320 - 320B, 320BRC, 320P and 320P/D portable oxygen analyzers

Model 320BRC with analog meter

     Teledyne’s rugged 320 Series of Portable Oxygen Analyzers are designed for use in a wide variety of applications from diving to fine tuning boilers.

     Lightweight (less than 6 lbs. / 2.7 kg) and easy to use, these units utilize Teledyne’s own Micro-fuel Cell sensor for quick and accurate analysis of oxygen.

     This maintenance-free, sealed, electrochemical cell is specific to oxygen, insensitive to flow rate, and has a 90% response in less than 7 seconds. At the end of its life, the cell is discarded and replaced like a flashlight battery. A unique Cell-Saver cap preserves the sensor from exposure to air, thereby prolonging its operational life.

     The rugged 320 Series is powered with rechargeable NiCad batteries. The integral NiCad batteries have an expected life of 5 years (minimum). Fully charged, the batteries provide over one month of continuous operation (320BRC series), and recharging is accomplished overnight (14 hours).

     The built-in charger requires a 115 VAC, 50 / 60 Hz electrical source (100 VAC or 220 VAC, 50 / 60 Hz optional). Teledyne’s portable flue gas oxygen analyzers are specifically designed to improve efficiency, lower fuel costs, and reduce explosive hazards in such applications as power plants, refineries, chemical / petrochemical plants, and steel making.

     When used to monitor boilers, fireboxes, and process streams, these analyzers can safeguard combustion processes from insufficient or excessive oxygen conditions.

Model 320P/D with digital meter

     The 320P/D also offers a digital, liquid crystal display (LCD) with a readability / resolution of ±0.1% oxygen. Linear range is 0-100% oxygen.

     The Series 320 requires no warm up, making it ideal for quick, spot checking analysis. Its accuracy is assured by a cost-effective calibration method using atmospheric air rather than zero or span gases.
