Climate information when it matters
Monitor spaces such as an office, server room, storage area, or greenhouse. Charts help you review how conditions change over time.
LifeQuality Lite measures temperature and humidity. For a model with CO₂ monitoring, see the CHM LifeQuality Jeweller page.
A measured response to changing conditions
Configure compatible automation devices to control equipment when temperature or humidity crosses a selected threshold.
CHM checks the control equipment, system compatibility, and required scenario before configuration. The monitor provides the measurement; compatible automation equipment performs the switching.
Designed for demanding temperatures
The device’s specified operating range is −30 °C to +50 °C. Battery life depends on the environment, radio conditions, and device settings.
The included replaceable CR123A batteries support up to five years at room temperature or up to two and a half years at sub-zero temperatures.
Installation without power cabling
Use the SmartBracket mounting panel or select a suitable flat surface. A built-in accelerometer detects device movement.
CHM checks placement, radio communication, threshold settings, and charts after adding the monitor to a compatible Ajax system.
