Vaisala DMT340 Industrial Dewpoint and Temperature Transmitter -60°C to 80°C

The *Vaisala DMT340* is a high-precision dewpoint and temperature transmitter designed for industrial environments such as compressed air drying and metal treatment. This device employs advanced DRYCAP sensor technology, ensuring resilience against particulate contamination, water condensation, oil vapor, and most chemicals, which is critical in industrial and biotechnological processes requiring robust environmental control.

Key technical features include:

• Measurement range covering dewpoint temperatures from -60°C to 80°C (-76°F to 176°F) and air temperatures from 0 to 80°C (32 to 176°F), with high accuracy of ±0.004% RH and ±0.2°C temperature accuracy.
• Fast response time of approximately 30 seconds, supporting timely monitoring in process controls.
• An integrated LCD display with a graphic and numeric interface offering a user-friendly menu for configuration and real-time readings.
• One-year datalogging capability, storing comprehensive dewpoint and temperature data essential for process validation and quality control in molecular diagnostics and bioprocessing pipelines.
• Fully automatic self-calibration feature maintaining accuracy over long-term industrial applications.
• Output via 4–20 mA signal compatible with various control systems in synthetic biology research facilities and biomanufacturing environments.
• Power supply between 10 to 35 VDC with included power cord for easy installation.

Weighing 2.18 kg (4.8 lbs), the DMT340 supports precise humidity and temperature monitoring indispensable for biotechnology labs, clinical diagnostics, and biomedical engineering applications, where environmental stability is critical. Its durability and stability at ultra-low dewpoints make it widely adopted in synthetic biology research and molecular cloning workflows that require stringent moisture control.

This preowned unit was manufactured in 2020 by Vaisala, a Finnish company renowned for industrial measurement solutions. It remains fully functional despite minor cosmetic scratches and does not include a computer. The unit's robustness ensures reliable use in damp or contaminant-rich environments, making it an essential instrument in biopharmaceutical production pipelines and related research fields requiring stringent environmental monitoring.
