ESPEC Bench-Top Type Temperature (& Humidity) Chambers SH / SU Series

Compact but realizing efficient environmental for testing with high-performance networking

The bench-top-sized thermo-hygrostat and small-sized environmental testing equipment are compact but have full-scale environmental testing performance.
Temperature change rate of 5.0°C per minute is added to the temperature (humidity) range combined with internal capacity of 22.5L and 64L. A total of 12 models are available.
The newly developed N instrumentation incorporates a color touch panel, offering operability and visibility similar to those of the well-reputed Platinus J series.
