Quick Overview

UEi C30 Smart Bell Plus Combustion Tester Meter improves on the Smart Bell by adding CO measurement and significantly lowers the cost of owning a combustion analyzer through EOS Technology (Electro-Optical Sensor) which uses optics instead of chemicals to take readings and extends expected sensor life to up to 10 years. The UEi C30 Smart Bell PLUS is a great replacement for technicians currently using a chemical wet kit or a great introduction to combustion analysis. Made in the United Kingdom.  Ground Shipping Free in Continental US. Read UEi C30 Smart Bell Plus Review >

Customer Reviews

simple unit Review by franklin

I wanted to get a simple unit to have around that wasn't too expensive that i could use for quick jobs and checkups. This fits that description well and i could find myself recommending it if someone asked me.

nice package deal Review by Robin Mendez

unit works great once you figure out how to operate it. I really like carrying bag instead of the hard case that other products come in. This unit has a lot of functionality for the price.

loooong life sensors Review by David Sanchez

This unit works well and i like the use of CO and CO2 sensors to measure and then uses that to calculate the Oxygen %. This gives you way longer sensor life than normal. Very great base analyzer for simple residential work.

Personal use Review by CheapSkate

I purchased this unit so I can randomly inspect my own system to make sure everything is up to snuff. I figure it doesnt hurt to brush up on how my system works so I dont get hosed by a furnace guy looking to make some extra money off me. Seems simple to use and the owners manual really explains things quite well.

Unique starter Meter Review by TonyRomo4president

I'll be honest, this not the most intuitive unit to use at first. After reading the manual it all makes sense and seems obvious. You select the fuel source before turning the unit on then it is set to that fuel and use it like it normal. Otherwise, a good unit that is letting me get my feet wet in the furnace business.

Easy Review by Gary

This little guy is great for basic contract work. Simple to use and takes all the measurements you need for tuning residential furnaces and the like. Good starter meter.
