The BH-90A ozone product contains six O3 range variants with different resolution labels. These are separate purchase configurations. Start with the concentration span and reading increment needed for the measurement, then compare sampling and package details.
Choose the Configuration for Your Measurement
- Lower ranges: 0-10, 0-20 and 0-50 ppm options are labeled 0.1 ppm.
- Other ranges: 0-100, 0-1000 and 0-5000 ppm options are labeled 1 ppm.
- Comparison: Do not infer a built-in pump from the BH-90A family name; compare explicitly pumped K-600 and SKY2000 options if needed.

Compare the Relevant Alternative
K-600 explicitly states built-in-pump sampling and offers 0-50 ppm / 0.1 ppm and 0-100 ppm / 1 ppm options. BH-90A provides a wider range menu on this page. Compare the exact selected versions rather than their shared gas name alone.

Questions Before Ordering
Why do the range labels include different resolution numbers?
The current variants pair a span with a reading increment. Keep that pair together; the lower-range 0.1 ppm label is not carried over to the 0-5000 ppm version.
Can one BH-90A order use every O3 range?
No range-switching capability is established by the variant menu. Select one listed configuration before ordering.

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.
