OxyCheq Helium Analyzers
The OxyCheq Expedition Helium Analyzer # OA-01-03 (old #OA-5) is their most recent analyzer. It is small, very portable, very accurate and extremely easy to use. -- OxyCheq He Gas Analyzers

OxyCheq
Expedition He Analyzer

Helium Analyzer
Item: OA-01-03 -- The OxyCheq Expedition Helium Analyzer is their most recent analyzer. It is small, very portable, very accurate and extremely easy to use. The monitor is small, easy to use with a rechargeable battery system guarantying long life and accurate performance. The monitor is temperature compensated to assure little to no drift in the measurement.

Unlike other products that must rely on very accurate flow control, temperature control, and specific gas volume, the Expedition Helium Analyzer requires a reasonable gas flow through the sensor, and a one-minute shunt to acquire accurate results over and over again.

Teledyne MIXCHEK
He / O2 Combo Analyzer

He & O2 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.
