Advanced Performance for Critical Environments

Built to withstand the rigors of industrial and cleanroom settings, the RHT MOD offers IP65 protection and a durable ABS plastic/metal enclosure. Its highly responsive sensors provide accurate humidity and temperature readings within seconds, ensuring that environmental control standards are met effectively and promptly.


Easy Installation and Flexible Integration

The RHT MODs wall-mount design, standard probe size, and selectable output signals (4-20mA or 0-10V) streamline setup and integration into existing systems. Optional RS485 Modbus communication and a large LCD display facilitate both remote monitoring and on-site data verification, enhancing usability across various applications.


Reliable and User-Friendly Calibration

Every RHT MOD unit is factory calibrated, guaranteeing out-of-the-box accuracy. Should recalibration be necessary, field recalibration is simple, ensuring consistent precision over time and helping users maintain confidence in their measured data.

FAQs of RHT MOD:


Q: How is the RHT MOD installed and where can it be mounted?

A: The RHT MOD is designed for simple wall mounting with its compact dimensions (approx. 130mm x 70mm x 35mm). Its IP65-rated enclosure allows it to be securely installed in industrial, cleanroom, and HVAC environments, offering protection from dust and water ingress.

Q: What output signal options are available, and how can I select them?

A: This device supports both 4-20mA and 0-10V output signals, allowing compatibility with a wide range of monitoring and control systems. You can select the desired output during installation to match your specific system requirements.

Q: When is recalibration necessary and how is it performed?

A: While the RHT MOD is factory calibrated for immediate use, periodic field recalibration can be conducted as needed to maintain measurement accuracy. The process is user-friendly and can be performed on-site, minimizing downtime and ensuring reliable long-term operation.

Q: What benefits does the quick response time provide in practice?

A: With a response time of less than 5 seconds to humidity changes, the RHT MOD delivers near real-time environmental data. This speed is essential for critical applications where quick adjustments to humidity and temperature are required to maintain optimal operating conditions.

Q: How does the RHT MOD ensure precise measurement and reliability?

A: The device uses industry-proven capacitive humidity and RTD temperature sensors, delivering high accuracy (2% RH, 0.5C) and resolution (0.1% RH, 0.1C) across wide measurement ranges. Factory calibration and durable materials further guarantee consistent and reliable operation.

Q: What is the recommended operating environment for this equipment?

A: The RHT MOD is engineered for industrial, cleanroom, and HVAC applications. Its robust construction and wide measurement ranges (0100% RH, -40C to +60C) make it suitable for aggressive and regulated environments where accurate control is essential.
