Product description

Industrial-grade Vaisala DMT340 transmitter accurately measures dew point to -60°C with DRYCAP sensor and 4-20mA output.

The Vaisala DMT340 Dewpoint and Temperature Transmitter is engineered for demanding industrial environments such as compressed air drying and metal treatment, ensuring precise and reliable environmental monitoring critical in biotechnology and molecular diagnostics workflows.

Key technical features include:

  • DRYCAP sensor technology resistant to particulates, water condensation, oil vapor, and chemical contaminants
  • Dew point measurement range from -60°C to 80°C with ±0.004% RH accuracy and temperature accuracy of ±0.2°C
  • 4-20mA analog output compatible with industrial process control systems
  • Equipped with a graphic LCD display and menu-based user interface for intuitive operation
  • Supports data logging with storage capacity for up to one year of historical moisture and temperature trends
  • Auto-calibration function that maintains long-term measurement accuracy without manual recalibration
  • Robust design with power input range from 10 to 35 VDC and rapid response time of 30 seconds

This transmitter is widely adopted in biotechnology process monitoring and biomanufacturing environments where precise humidity and temperature control are essential for gene editing, synthetic biology, and molecular cloning workflows. Its durability and advanced sensor technology make it a critical instrument for clinical diagnostics labs and research facilities focused on live-cell imaging and fluorescence analysis.

Dimensions are compact and suitable for benchtop or inline industrial installation: 4.5" height × 7.25" width × 3" depth, weighing 2.18 kg (4.8 lbs). The unit is preowned but fully operational, including power cord readiness.

This Vaisala DMT340 model supports sophisticated moisture measurement applications, offering reliable dew point analysis critical in environmental monitoring systems and industrial biotechnology processes.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
