Precise dewpoint and temperature transmitter with DRYCAP sensor, LCD display, and one-year humidity data logging.
The Vaisala DMT340 is a high-precision dewpoint and temperature transmitter engineered for *industrial environmental monitoring* and *compressed air drying* applications. Equipped with the durable DRYCAP sensor, it offers exceptional resistance to particulate contamination, water condensation, and chemical interference, ensuring reliable performance in dry and demanding conditions. This transmitter provides accurate measurements of dewpoints down to -60°C with a relative humidity range of 0–70% RH and an accuracy of 0.004% RH at 20% RH. Temperature measurement ranges from 0°C to 80°C with ±0.2°C accuracy.
Features include a user-friendly LCD display with a menu-based interface to facilitate configuration and monitoring. The device supports extensive one-year datalogging of humidity and temperature parameters for thorough environmental tracking. Automatic self-calibration enhances long-term stability and measurement consistency. Output is provided via a 4-20 mA signal compatible with industrial control systems. Powered by 10 to 35 VDC, the compact transmitter (dimensions 4.5 × 7.25 × 3 inches) weighs approximately 2.18 kg.
This transmitter is essential for biotechnology laboratories requiring precise humidity control during bioprocessing and molecular diagnostics, as well as for facilities involved in synthetic biology workflows, where environmental conditions critically impact experimental reproducibility. Its robust sensor technology and logging capabilities make it popular among researchers and industry professionals engaged in biopharmaceutical production pipelines and clinical diagnostics requiring stringent dewpoint and temperature monitoring.
This Vaisala transmitter supports precise environmental control, critical in applications like live-cell imaging, fluorescence analysis, and biomanufacturing quality assurance, making it a vital instrument for advanced biotechnology research and industrial process monitoring.
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.
