The ST9700 is a handheld carbon monoxide meter that combines 0-1000 ppm CO measurement with a separate ambient-temperature reading. Its LCD color display, adjustable alarm point and three-AAA power supply distinguish it from rechargeable CO monitors with range selectors.
Choose the Configuration for Your Measurement
- CO measurement: 0-1000 ppm range and 1 ppm resolution.
- Temperature: The stated ambient-temperature span is 0-50 °C / 32-122 °F; this is not a flue-gas analysis specification.
- Power: Three AAA 1.5 V alkaline batteries are required and are not included in the listed package.

Compare the Relevant Alternative
Both ST9700 and AS8700A pages describe CO concentration plus ambient temperature and three-AAA operation. Review the display layout, alarm controls and automatic power-off behavior in each model description before choosing. Do not infer a complete combustion-analysis function from the word analyzer.

Questions Before Ordering
Does the temperature function measure a boiler flue?
The product specifies ambient temperature from 0-50 °C. No flue probe or combustion-analysis capability is established by this specification.
Is the factory alarm point the right setting for every task?
The source gives a preset alarm point and says it can be adjusted. Use the instrument instructions and the applicable monitoring procedure when setting it; a factory value is not a universal exposure limit.

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.
