Testo 6631 Humidity/Temperature Transmitter

The Testo 6631 transmitter for greenhouses and laboratories is designed for monitoring of humidity and temperature in controlled environments. It provides reliable data for bio research, greenhouse management, and laboratory applications where accurate climate measurement is critical. The integrated ventilator enables targeted airflow over the sensor, recording an averaged climate inside the measurement cell, while P2A software allows efficient parameterization, adjustment, and analysis to save time during commissioning and maintenance.

The transmitter features replaceable humidity sensors and ventilators, minimizing downtime, and offers protection against moisture and sprinkler exposure. It measures 0 to 100% RH with ±2.5% RH accuracy and ±0.9°F measurement uncertainty. Quick ventilator replacement and plug in sensor filters further streamline service, while optional LCD display provides clear readout. Durable, UV-resistant plastic housing with IP65 protection ensures reliable operation under harsh conditions.
