Laboratory Humidifiers From Smart Fog
Three things set Smart Fog’s lab systems apart:
- Non-wetting dry fog: droplets of about 4.2 microns evaporate before they reach surfaces.
- Automated, precise control: S Series sensors and a CPLC controller hold setpoint within 1 to 2%.
- Four ways to install: wall-mounted, in-duct, custom grid and portable.
How Humidity Affects Lab Work
Many materials and instruments respond to humidity, so uncontrolled moisture adds a variable to every result. Standard test atmospheres, such as 23°C and 50% RH for paper (TAPPI T 402) and plastics (ASTM D618), exist for exactly this reason.
When humidity is too low
Problems that appear when lab humidity drops too low:
- Static discharges increase, disturbing analytical balances and damaging electronics
- Samples and biological materials dry out, shrink or crack
- Charged surfaces attract more dust
When humidity is too high
Problems that appear when lab humidity is too high:
- Condensation forms on cold surfaces and sensitive electronics
- Mold and microbial growth become a risk
- Hygroscopic samples and reagents absorb moisture, changing weights and reaction rates
Non-Wetting Humidification for Laboratories
Smart Fog’s laboratory humidity control systems add moisture as dry fog, so humidity rises without wet surfaces, and they run with minimal maintenance.
Non-Wetting Hydration:
Droplets of about 4.2 microns evaporate within seconds, before they reach benches, samples or instruments.
Even coverage:
Fine droplets spread evenly so readings match across the room, and the controls adjust output as occupancy and equipment loads change through the day.
Documented, steady conditions:
Humidity held within 1 to 2% of setpoint, with optional data logging over Modbus or BACnet, supports the records your quality system, GLP or GMP program requires. The range itself is set by your methods and validation.
Why Humidity Control Matters in Laboratories.
Stable humidity protects data integrity, repeatability and instrument life. Pharmaceutical, biotech and materials labs in particular rely on consistent conditions in testing rooms, storage areas and sample preparation, because a result that cannot be repeated is a result that cannot be used.
Benefits of Humidifiers for Laboratories
Precise humidity control protects your people, processes and instruments, without wet spots or waste.
Stable research conditions:
One less environmental variable in long-running experiments.
Sample integrity:
Consistent humidity limits evaporation, degradation and moisture uptake in reagents and samples.
Easier documentation:
Steady, logged conditions make audits and method validation simpler.
Lower maintenance:
No boiler to descale and no moving parts in the nozzles.
Instrument protection:
Less static and no condensation around sensitive equipment.

FAQs
What humidity should a laboratory maintain?
It depends on the work. Many test methods condition samples at 23°C (73.4°F) and 50% RH, and general labs often run between 30 and 60%. Your methods and validation set the range; the humidifier’s job is to hold it.
Why does a lab need a dedicated humidifier?
Building humidity drifts with the weather and occupancy. A dedicated system holds each lab at its own setpoint, so results do not change with the season.
Will it work in a cleanroom?
Yes. Running on purified water, dry fog adds no particles or condensation. See the cleanroom humidification page for details.
Is the system high maintenance?
No. Upkeep is mainly water filter changes and periodic inspection; there is no boiler to descale and no moving parts in the nozzles.
Can I scale Smart Fog humidifiers across multiple rooms?
Yes. Systems are modular: add units room by room, or humidify several labs through the air handling system with an in-duct unit.
