OxyCheq Analyzers

The OxyCheq Expedition - X | Model: OA-01-02 (Old # ROA-2) is identical to the OxyCheq Expedition O2 Analyzer except that it has an external Teledyne R-17D Oxygen sensor on a cable and additional connectors. | OxyCheq Expedition Oxygen Analyzers and Helium Analyzers | Technical Diving Equipment

Item: OA-01-02

OxyCheq Expedition X O2 Analyzer

The OxyCheq Expedition - X is identical to the Expedition except that it has an external Teledyne R-17S Oxygen sensor on a straight 6' cable.

Includes:
Case, Sensor Cap, and Sensor Tee

 

Price: $299.00   add OxyCheq Expedition-X O2 Analyzer OA-01-02 (ROA-2) to cart

The Expedition-X is a result of our customers' requests for an analyzer with an external oxygen sensor. They wanted the same performance and durability of the Expedition, but desired an external cell that they could use for specific applications. Hence, the Expedition-X was developed. The Expedition-X can easily be panel mounted for use with mixing stations. The Expedition-X has an electronic circuit that is easy to calibrate and uses a long life, fast response sensor. We used the newest and most reliable parts made and enclosed the electronics in a compact, sturdy, custom molded, scratch and UV resistant, anti-static, ABS case. The case, digital panel meter, potentiometer, on/off switch, and sensor, are sealed to protect the electronics inside the enclosure from harsh elements. It is splash-proof when the cable is connected to the analyzer. OxyCheq Expedition X Manual

Teledyne Helium Analyzers

The Teledyne MIXCHEK He / O2 is a portable instrument designed to accurately monitor the composition of both oxygen and helium. The case is environmentally sealed. It has a +/- 1% accuracy across the entire 0-100% analysis range (He / O2). Teledyne R-33D1 Oxygen Sensor included! | OxyCheq and Teledyne He and O2 Gas Analyzers | Technical Diving Equipment

Teledyne MIXCHEK He / O2 Combo Analyzer

 
Item: OA-02-04 -- The Teledyne MIXCHEK is a portable instrument designed to accurately monitor the composition of both oxygen and helium. The case is environmentally sealed. It has a +/- 1% accuracy across the entire 0-100% analysis range (He/O2). The MIXCHEK analyzes the Oxygen and Helium concentrations in a gas mixture using a dedicated two-channel sensor network sharing a common sample system.

A high output micro-fuel cell is used to determine the oxygen concentration of the gas mixture. The output of the micro-fuel cell is fed to the display and read out as percent Oxygen. Next, sample gas is directed to a thermal conductivity sensor. A microprocessor compares the sensor output to data contained in an onboard chip and converts the raw data into a signal that is sent to the Helium LCD display. No Helium Sensor To Replace!

Special order. Please allow additional lead time.

Case Included
