ELH Series

The Edgetech Instruments Model ELH Series is a series of precision humidity chambers, with NIST traceable accuracies in humidity (±0.5% typical), temperature (±0.1°C) and dewpoint (±0.2°C). The ELH Series consists of a programmable controller for constant precision control and uniformity, and an integrated DewMaster chilled mirror hygrometer for accurate temperature and humidity measurements.

The ELH series offers three standard chamber sizes: 1.5cu.ft., 6cu.ft. and 10cu.ft. Larger volume chambers are also available. All chambers use an environmentally safe non-depleting refrigerant.
