Replacement MX6 Sensor for Ammonia (NH3). Range 0 to 500ppm, Resolution 1ppm. Response Time 21 Seconds (T50)
£642.00
Ammonia (NH3) is a colourless gas with a characteristic pungent, suffocating odour. It is highly soluble in water and is often encountered as an aqueous solution (e.g., household ammonia). While naturally occurring and essential for biological processes, it is also widely used in industry and can be hazardous in concentrated forms or in poorly ventilated areas.

Sensor may become unstable, if the battery is removed from the instrument or after the low battery warning is activated. If either incidence occurs, change the battery (or re-install the existing battery if it has suitable life remaining), then power the monitor ON then OFF, and allow at least 24 hours for the sensors to stabilise.

The table above reflects the percentage response provided by the sensor (top row) when exposed to a known concentration of the target gas (column 1).
The numbers were measured under these environmental conditions: 20 °C (68 °F), 50% RH and 1 atm.
The specified cross-interference numbers apply to new sensors only and may vary with time as well as from sensor to sensor.
“-” means no data available.
