Product Description

Environmental changes in cleanrooms, labs, warehouses, and industrial facilities can go undetected and cause invisible damage, compromise delicate processes and lead to non-compliance issues.  Manual verification, and insufficient monitoring systems can be unable to prevent environmental changes from going unnoticed until after harm is already done.

 An increase in RH or temperature of just a few degrees might appear small until it results in:

  •  Spoiled or contaminated product
  •  Failing quality assurance inspections
  •  Damage to sensitive products/equipment
  •  Inefficiencies within HVAC systems
  •  Operational losses through increased downtime

With a lack of appropriate monitoring, it's easy for environmental problems to be an unknown issue until product/equipment damage has already occurred, and it can become an issue of high cost and risk for industries where environmental consistency is key.

The AI-RHT4 Temperature & Humidity Indicator allows for real-time environmental monitoring that gives your facility a tool for maintaining control. Its easy-to-read digital display, rapid sensor response and dependable accuracy in the most demanding applications provide continuous monitoring for your needs. Built for the rigors of the industrial environment, the AI-RHT4 ensures that the most critical environment is in your control.


Features

  • Monitor both Temperature and Relative Humidity simultaneously on a single device with large 4" high-brightness red LED displays for instant, at-a-glance readings
  • React immediately to environmental shifts with a resolution of 0.1 across both measurements and accuracy of ±0.3°C for temperature and ±1.8% RH for relative humidity
  • Ensure high reliability of your process and adherence to standards with optional RS485 Modbus Protocol communication for seamless BMS/SCADA integration
  • Safeguard delicate products and machinery with a robust wall-mount mild steel cabinet featuring powder coating for superior rust protection and IP-68 rated cable glands
  • Reduce operating risk and the necessity for monitoring, and regain control of your environment in harsh situations with a built-in or external wired capacitive polymer combination sensor covering 0.0 to +60.0°C and 0.0 to 99.9% RH

Applications

  • Museums and archives
    Protecting artifacts, documents, and collections requires precise environmental control. The AI-RHT4 provides continuous, high-visibility monitoring of temperature and humidity levels, helping conservators prevent deterioration caused by moisture fluctuations and maintain conditions that meet international preservation standards.
  • Greenhouses & Agronomy
    Optimal plant growth depends on tightly controlled humidity and temperature. The AI-RHT4's wide measurement range of 0.0 to 99.9% RH and 0.0 to 60.0°C makes it well suited for greenhouse environments, giving growers real-time visibility into conditions and enabling faster corrective action when levels drift outside acceptable thresholds.
  • Electronics and Semiconductor Industries
    Excess humidity in electronics manufacturing environments can cause condensation, corrosion, and electrostatic discharge that damage sensitive components. The AI-RHT4 delivers accurate, continuous readings with ±1.8% RH precision and supports RS485 Modbus integration for automated monitoring and alerts within existing SCADA or BMS systems.
  • Industrial Production Areas
    Many manufacturing processes require stable temperature and humidity to maintain product consistency, equipment performance, and worker safety. The AI-RHT4's powder-coated mild steel enclosure and IP-68 rated cable glands make it durable enough for demanding industrial environments, while its large 4" LED display ensures readings are visible across the floor.
  • Commercial and Shopping Centers
    Maintaining a comfortable environment in large public spaces directly affects customer experience and energy efficiency. The AI-RHT4's jumbo display allows facility managers to monitor ambient conditions at a glance, and optional RS485 Modbus communication enables integration with centralized building management systems for streamlined climate control across multiple zones.
  • Cold Storage and Food Processing
    Temperature and humidity control is critical in cold rooms, food storage facilities, and processing areas to prevent spoilage, maintain compliance with food safety regulations, and extend shelf life. The AI-RHT4 provides reliable, continuous monitoring with clearly visible readings and the option for remote data integration into existing facility management infrastructure.
  • Pharmaceutical and Healthcare Facilities
    Drug efficacy and medical supply integrity depend on strict adherence to defined temperature and humidity ranges. The AI-RHT4 supports regulatory compliance by providing accurate, real-time environmental data with ±0.3°C temperature accuracy, along with Modbus communication capability for audit-ready data logging and integration with central monitoring systems.
