This single-gas product offers 18 gas-and-range order configurations. Select one gas, its span and its unit; the option list does not mean one instrument measures all 18 configurations simultaneously. Some gases appear more than once because the range or unit differs.
Choose the Configuration for Your Measurement
- One configuration: Each variant represents the selected gas and range for the order.
- Unit differences: CO2 appears with ppm and volume labels; C2H4 appears with ppm and LEL labels. Those are separate choices.
- Less common options: Current labels include SO2-0-20ppm-0.1 and C2H4O-100ppm-1. Use these exact labels and SKUs rather than borrowing a specification from another gas row.

Questions Before Ordering
Does the 0-100% LEL table apply to every selectable gas?
The gas-and-range selector contains different units and spans. Use the chosen option and its confirmed documentation; do not apply a generic table value to all variants.
Can I order ethylene oxide and ethylene interchangeably?
No. C2H4O and C2H4 are separate option identities. Preserve the full gas name, variant label and SKU when confirming an order.

My first impression after opening and installing batteries was that this meter is very well built considering the price and manufacturer. I had read some reviews stating that it's amp measurements were not accurate below 5 amps, I haven't seen any issues in any measurements I've taken, even side by side with my fluke meters. I've successfully taken accurate amp, voltage and continuity measurements with this ETCR6920B, the display is nice and legible. I haven't tried storing data and making transfers to a PC yet, the soft case is good enough for storage on a shelf and the test leads are of good quality and rated for 1000v. There's nothing bad to say about this meter especially when you consider the price, it's a really great meter.
Works as described.
