6621 HVAC Temperature & Humidity Transmitter by Testo

A broad variety of the testo 6621 transmitter is available. Depending on the application in a room or in a duct, the corresponding designs can be selected. A display and an external probe are available as options. You can choose between the housing colours grey and white. The testo 6621 is persuasive in technical terms thanks to the patented humidity sensors that guarantee the highest accuracy. The sensors and the analog outputs can be adjusted, analyzed and parameterized via the external interface using the P2A software.

The testo 6621 is a high-performance transmitter for a low price. It meets the increasing requirements in automated building services in terms of accuracy, reliability and safety and thereby saves energy costs.

• Highly accurate testo humidity sensor with long-term stability (±2.0% RH)
• Optional 2-line LCD display
• P2A software for parameterization, adjustment and analysis, saves time and costs in commissioning and maintenance
• Optimum calibration concept thanks to adjustment of the entire signal chain (1-point, 2-point and analog adjustment)
• Adjustment without dismantling the transmitter
• 2 analog outputs (humidity/temperature), option of 1 passive humidity and temperature analog output
