Suitable for laboratory work and on-site humidity checks
The Vaisala MGP262 continuously measures methane slip and carbon dioxide in offgas from biomethane-upgrading processes. Its in-situ design provides direct, always-on measurement without a separate sampling system.
Optimised for low-level methane measurement in CO2-rich offgas
CH4 measurement range from 0–5 vol-%
CO2 measurement range from 0–100 vol-%
Heated optical measurement for demanding and humid process conditions
Three isolated 4–20 mA outputs and RS-485 Modbus RTU
Ex-certified construction for direct installation in hazardous process areas
The Vaisala DMT340 Series provided configurable dew-point and temperature measurement for industrial low-humidity applications. The series is discontinued and replaced by Vaisala Indigo500 transmitters with DMP7 or DMP8 smart probes.
Former models: DMT341, DMT342, DMT344, DMT347 and DMT348
Designed for dry rooms, industrial dryers, compressed air and process gases
Legacy display, data logging, analog, relay and communication options
Use DMP7 for compact, wall-mounted or tight-space applications
Use DMP8 for pressurised processes and pipelines
Pair the selected probe with an Indigo500 transmitter
The Vaisala DMT345 and DMT346 provided direct dew-point measurement in hot industrial drying processes. Both models are discontinued and replaced by Vaisala DMP5 or DMP6 smart probes with an Indigo transmitter.
DMT345: former solution for processes up to +180 °C
DMT346: former solution for very hot processes up to +350 °C
DMT345 replacement: DMP5 with a suitable Indigo transmitter
DMT346 replacement: DMP6 with a suitable Indigo transmitter
Direct in-process measurement without a conventional sampling system
