Vertiv Geist GTHD Temperature, Humidity, and Dew Point Sensor
The Vertiv Geist GTHD Temperature, Humidity, and Dew Point Sensor is a compact, high-precision environmental monitor designed to protect critical IT equipment in data centers, server rooms, and enterprise facilities. By continuously tracking temperature, relative humidity, and dew point, this sensor helps data-center teams maintain optimal environmental margins, prevent condensation risks, and support reliable cooling strategies. Built to integrate with the Geist monitoring ecosystem, the GTHD delivers real-time data, trend analysis, and actionable alerts that empower operators to optimize airflow, reduce energy waste, and extend the life of expensive gear.
Engineered for demanding environments, the GTHD combines accurate sensing with robust construction and flexible deployment. Its small form factor makes it easy to mount at rack, cabinet, or ambient locations, while its network-ready design enables seamless integration into centralized monitoring dashboards. IT teams benefit from proactive notifications, historical data, and scalable coverage as facilities grow—from a single rack to an entire data-center campus. In short, the GTHD is a trusted companion for maintaining safe operating conditions, improving overall reliability, and delivering peace of mind in mission-critical spaces.
- Real-time environmental data: The GTHD provides continuous measurements of temperature, relative humidity, and dew point with prompt update rates, so operators can detect and respond to changes before they impact equipment performance.
- Dew point awareness for condensation prevention: By monitoring dew point alongside temperature and humidity, the sensor helps predict condensation risk—crucial in cooling-down scenarios, humid environments, and mixed-heat zones typical of data centers.
- Configurable alerts and alarms: Threshold-based alerts let administrators set critical ranges and receive prompt notifications through the Geist platform, email, or SNMP traps, enabling rapid containment and reduced risk of downtime.
- Seamless Geist integration for centralized monitoring: Designed to work within the Vertiv Geist software stack, the GTHD feeds dashboards, alarms, and historical trends into a unified view—supporting scalable deployments across racks, rows, and multiple rooms.
- Flexible deployment for diverse environments: Its compact, rugged form supports mounting at various points in the data center, from rack rails to cabinet interiors, ensuring comprehensive coverage without gridlock or clutter.

how to install Vertiv Geist GTHD Temperature, Humidity, and Dew Point Sensor
Installing the GTHD is straightforward and designed to minimize disruption to ongoing operations. Follow these steps to deploy quickly and start collecting actionable environmental data:
Step 1: Choose the installation location. Identify strategic sites near critical equipment, cooler exhausts, or air intake zones that best represent the room’s conditions. Avoid direct heat sources, sunlight, and obstructions that could skew readings.
Step 2: Prepare mounting hardware. Use the supplied brackets and fasteners to attach the sensor securely to a rack rail, cabinet interior, or wall surface as appropriate for your facility layout. Ensure the unit remains accessible for inspection and maintenance.
Step 3: Establish network connectivity. Connect the GTHD to your existing Geist monitoring network using the recommended Ethernet interface. Confirm that the device obtains network access and can communicate with the Geist server or management console.
Step 4: Power up and initialize. Apply power according to the SKU’s guidelines and verify that the indicator lights (if present) show normal operation. Allow a brief stabilization period for readings to settle after power-up.
Step 5: Integrate with Geist software. In the Geist interface, add the new GTHD sensor, assign it to the correct location (rack, row, or room), and configure naming conventions so dashboards are intuitive for your operations team.
Step 6: Set thresholds and alerts. Define acceptable ranges for temperature, humidity, and dew point relevant to your equipment and cooling strategy. Configure notification channels (email, SNMP, or other channels supported by Geist) to receive timely alerts when values exceed safe limits.
Step 7: Validate deployment. Compare live readings with known reference points, review historical trends, and confirm that alerts trigger appropriately when simulated conditions approach defined thresholds. Document the installation for ongoing maintenance.
Step 8: Maintain and calibrate. Periodically verify sensor accuracy through routine checks or due to environmental changes. Replace or service sensors per Vertiv guidelines to maintain reliability over time.
Frequently asked questions
- What does the Vertiv Geist GTHD sensor measure?
- Why is dew point monitoring important in a data center?
- How does the GTHD integrate with Vertiv Geist software?
- Can I deploy the GTHD in different locations within a data center?
- What should I consider during installation and commissioning?
The GTHD measures temperature, relative humidity, and dew point. It provides real-time environmental data to help data-center teams manage cooling efficiency, humidity control, and condensation risk in server rooms and data centers.
Dew point monitoring helps predict when humidity and temperature conditions could cause condensation on IT equipment. By tracking dew point alongside temperature and humidity, operators can take proactive steps to adjust cooling or airflow, reducing the likelihood of condensation-related damage and corrosion.
The sensor is designed to feed its readings into the Geist software platform, enabling centralized dashboards, historical trends, and alerting. This integration supports scalable deployments—from individual racks to entire facilities—while providing a single pane of glass for supervision and response.
Yes. The GTHD is designed for flexible deployment and can be mounted on rack rails, inside cabinets, or at ambient locations to capture representative environmental conditions across multiple zones. This flexibility helps ensure comprehensive coverage without clutter and complex wiring.
Consider placement away from direct HVAC vents and heat sources to avoid reading distortions, ensure proper network connectivity to the Geist system, and develop clear naming conventions and threshold policies to maximize the usefulness of dashboards and alerts. Regular maintenance, calibration checks, and documentation will also help sustain reliability over time.
