UEi Test Instruments
has a broad product line of quality and innovative testers for the HVAC/R, electrical, and automotive industries. UEi backs it's products by providing industry-leading warranties, knowledgeable technical phone support, and prompt maintenance and repair turnarounds.
Their product line encompasses many clamp meters, multimeters, thermometers, combustion analyzers, CO detectors, and combustible gas and refrigerant detectors. The UEi motto says: You will love this STUFF, and whoever owns UEi's tester really does.
The UEi Eagle X series of Combustion Analyzers C155 and C157 feature all new CO2 Sensor Technology which greatly reduces the cost of ownership for the device, since normal electro-chemical sensors tend to need replacement on an annual basis.
The Eagle X Series uses an Electro Optical Sensor (EOS) to take direct CO2 measurements and then calculates the O2 level. Additionally, these models include an extended life dedicated O2 sensor, which carries a 5 year limited warranty and significantly reduces sensor replacement frequency. All of the UEi Combustion Analyzers are made in UK.
