Rotronic HD1 Thermo Hygrometer Display

A. Product Overview

The Rotronic HD1 is a reliable thermo hygrometer designed for indoor air quality monitoring where stable environmental readings matter. It measures relative humidity, temperature and dew point and presents them on a clear display for quick checks and routine monitoring. The unit supports bench-top use or wall mounting, making it suitable for control rooms, laboratories, server rooms and storage areas.

HD1 includes max min avg tracking for better analysis, along with audible and visual alarms for out-of-limit values. It also displays time and date and updates measurements at a 10-second interval. The device is battery operated using 4 AA batteries with an approximate one-year battery life and it is supplied with a factory certificate.

B. Working Principle

Rotronic HD1 uses internal sensing elements to measure temperature and relative humidity of the surrounding air. The device then calculates dew point based on the measured temperature and relative humidity. Readings are refreshed at a 10-second measurement interval and shown on the display. When values exceed the configured limits, the unit provides alerts using an LED alarm indicator and a beeper, so users can react quickly to environmental deviations.

C. Why It Is Used

Rotronic HD1 is used when consistent indoor environmental monitoring is required for equipment protection, product quality and comfort control. It helps users track humidity, temperature and dew point and identify trends using max min avg values. Alarms provide immediate warning of high or low conditions, reducing the risk of condensation, static issues, corrosion, mold growth and process instability.

It is commonly used to support HVAC monitoring and to maintain controlled conditions in sensitive spaces such as server rooms, laboratories, cleanrooms, museums and archival storage areas. Its industrial accuracy, long battery life and simple installation make it practical for continuous monitoring without frequent maintenance.

D. Suitable Buyers

• HVAC technicians and facility managers who need indoor temperature, humidity and dew point visibility

• IT and data center teams monitoring server room environmental conditions

• Laboratories and R and D teams requiring reliable indoor air measurements

• Cleanroom and controlled area operators who need quick alerts for out-of-limit humidity or temperature

• Museums and archival storage managers protecting sensitive material from moisture and condensation

• Quality teams who want a simple monitoring display with tracking and alarm functions
