Description
The high-precision Testo 6741 dew point transmitter is engineered specifically for monitoring trace humidity in compressed air, dry air, and technical gases within industrial networks. Equipped with a premium Testo polymer humidity sensor, it offers exceptional measurement accuracy of up to +-1 K at 0 Ctd alongside certified long-term stability. The transmitter features a freely scalable analog output (4 to 20 mA) to convert measured values into standardized electrical signals. Designed with a compact housing that can be rotated by 350 degrees, the instrument provides optimum structural alignment across tight piping spaces.
Industry Applications
- Adsorption and Membrane Dryers: Optimization of regeneration air cycles based on precise humidity-controlled chamber activation to reduce consumption costs.
