Humidity Chambers

A humidity chamber is specified when the protocol sits above 80 %RH, where condensation, mould growth and sensor drift all appear at once. The cabinets here reach 95 %RH and hold it, with six-sided heating to stop condensation on the walls and a humidity sensor that survives sterilisation. The range runs from 56 to 241 litres, which covers packaging, components and biological samples.

APPLICATIONS

Humidity Chambers Applications & Use Cases

Application-led selection for real laboratory workflows.

Why high humidity is harder than low humidity

Above 85 %RH the chamber is close to saturation, and small temperature differences become condensation.

The sensor is the consumable

In a wet chamber the humidity sensor degrades faster than any other component.

Mould, spores and cleanroom practice

A chamber held at 90 %RH for months will grow things unless the design prevents it.

Sizing and water supply

Humidity chambers consume water continuously, and the supply is a site requirement.

PERFORMANCE & SELECTION

Why high humidity is harder than low humidity

Above 85 %RH the chamber is close to saturation, and small temperature differences become condensation.

A 0.5 °C cold spot on a wall at 90 %RH is enough to form droplets, which then drip onto samples.
Six-sided heating with a thermal jacket keeps every surface above the dew point.
Air exchange has to be smooth
a turbulent inlet creates local cold spots and condensation.
The drain has to handle continuous condensate, not just an occasional purge.

Why high humidity is harder than low humidity

CONFIGURATION & COMPATIBILITY

The sensor is the consumable

In a wet chamber the humidity sensor degrades faster than any other component.

Capacitive sensors drift in continuous high humidity
a sterilisation-rated sensor can be cleaned and dried.
A 160 °C sterilisation cycle on the chamber, sensors and air guide resets the biological load without chemicals.
That cycle is for the chamber, not for the samples
the manual is explicit about it.
Calibration at 20 %RH and 90 %RH, in situ, is the routine that keeps the reading honest.
