Select the Diffusion NH3 Range and Package
The MH-1200H-S-NH3 is the diffusion-sampling ammonia option in this comparison. Its listed range variants are ordered separately. Compare it for NH3 concentration checks where diffusion sampling fits the procedure, rather than choosing it as though it were the built-in-pump MH2000 model.
Listed Purchase Options
| Option | SKU |
|---|---|
| 0-100ppm | INS03-8098 |
| 0-200ppm | INS03-8099 |
| 0-500ppm | INS03-8100 |
| 0-1000ppm | INS03-8101 |
Select one listed option. Different ranges or pump configurations are separate supplied versions; they are not all combined in one unit.
Questions That Help You Choose
Is the required NH3 range an online variant?
Select the matching option from the SKU table below; the highest listed range is not the range of every unit.
Is a sampling pump included?
The source listing describes an external pump as an option. Confirm the pump and tubing package if the measurement task requires them.
Do I need to review earlier readings?
Compare the listed data logging and alarm-record functions with the records you need from the measurement.
For the buying comparison, read pump vs. diffusion selection and ammonia detection for refrigeration tasks.
Compare MH2000 internal-pump option.
Another Handheld NH3 Choice
The AR8500 NH3 monitor presents a single listed measuring span and a concentration/alarm display. This MH-1200H-S page instead offers separate range variants and describes an optional external-pump arrangement. Compare the range choice and sampling package you need rather than assuming those options belong to every NH3 monitor.
MH-1200H-S-NH3 Diffusion Ammonia Detector
This portable detector measures ammonia (NH3) for industrial, agricultural, refrigeration, and facility checks. It is sold as four separate measuring-range variants up to 1000 ppm. Choose the range that matches the expected concentration and the site's measurement procedure.
Choose the NH3 Measuring Range
| Selectable range variant | SKU |
|---|---|
| 0-100ppm | INS03-8098 |
| 0-200ppm | INS03-8099 |
| 0-500ppm | INS03-8100 |
| 0-1000ppm | INS03-8101 |
Resolution is 0.1 ppm or 1 ppm depending on range. Confirm the exact resolution for the selected range if it affects the measurement plan.
Detection Details
- Sampling: diffusion. An external sampling pump is described as an option for a different sampling setup.
- Alarms: sound, light, and vibration.
- Display: LCD dot-matrix display for gas type, real-time concentration, and gas unit.
- Records: data logging and alarm-record review on the device.
MH-1200H-S or MH2000?
| Selection point | MH-1200H-S-NH3 | MH2000-NH3 |
|---|---|---|
| Sampling arrangement | Diffusion; external pump described as an option | Built-in sampling pump |
| Range variants | 0-100, 0-200, 0-500, or 0-1000 ppm | 0-100 through 0-5000 ppm across six variants |
| Before ordering | Confirm whether an external pump and its tubing are needed and included | Confirm pump-mode runtime and the required range/resolution |

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.
