Indoor air quality monitor E04

industrialurban railCO2

Description
The digital multi-sensor measures ambient temperature, relative humidity and CO₂ concentration with high accuracy, providing climate data for demanding industrial and rail applications. Actively ventilated sensing elements ensure fast response times and allow concealed rear-wall mounting for integrated installations without compromising measurement performance.

Rugged design and approvals
Engineered for harsh operating conditions, the unit features very high vibration resistance for reliable long-term operation. Compliance with rail standards is verified by testing to DIN EN 61373 Category 1 Class A and conformity with DIN EN 50155 where applicable.
