Vaisala DMT340/341 transmitter measures dew points to -60°C with auto-calibration for industrial process monitoring.
The Vaisala DMT340 Dewpoint and Temperature Transmitter (model DMT341 variant) is engineered for demanding industrial applications involving dry air conditions, such as compressed air drying and metal treatment processes. Featuring a robust DRYCAP sensor, it reliably measures dew points as low as -60°C (-76°F) and temperatures ranging between 0°C to 80°C (32°F to 176°F) with high accuracy and long-term stability.
Key technical specifications include:
The transmitter’s DRYCAP sensor is highly resistant to particulate contamination, water condensation, oil vapor, and chemicals, making it suitable for harsh industrial environments. It incorporates Vaisala’s patented auto-calibration function that autonomously adjusts the calibration curve during measurements, ensuring measurement consistency critical in molecular diagnostics and bioprocessing environments.
The device features a user-friendly LCD display with graphic and numeric readouts, complemented by a menu-based interface that facilitates configuration and monitoring. Its built-in datalogging capability stores up to one year of dew point and temperature data, supporting trend analysis in applications including biomanufacturing process control and synthetic biology laboratories requiring precise environmental monitoring.
Weighing approximately 2.18 kg (4.8 lbs), this transmitter integrates seamlessly into industrial instrumentation setups for humidity and moisture analysis in biotechnology and environmental monitoring domains. This preowned unit remains fully functional with minor cosmetic wear and includes a power cord for immediate installation.
This Vaisala dewpoint transmitter is a critical instrument in molecular biology workflows and biotechnology research for maintaining optimal environmental conditions, ensuring data integrity, and safeguarding bioprocesses where moisture control impacts product quality and reproducibility.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
