Frequently Asked Questions
Why is humidity control as important as temperature in calibration?
Many environmental sensors (thermohygrometers, dew-point probes) measure both parameters. Temperature and humidity are interdependent—at a given temperature, 80% RH feels very different from 40% RH. Validating both simultaneously ensures accuracy for applications like pharmaceutical storage, food ripening, and data center monitoring.
How does the dew-point control function work?
Dew-point control automatically adjusts humidity based on temperature setpoint to maintain a precise dew-point value. For example, at 20°C, 50% RH equals a dew point of ~9°C. The system maintains that relationship, ensuring sensors experience realistic humidity-temperature coupling.
Can I use this for pharmaceutical stability testing?
Yes. Pharmaceutical stability studies per ICH Q1F require 25°C/60% RH, 30°C/75% RH, and 40°C/75% RH conditions. The 27L chamber's ±0.5°C and ±3% RH accuracy meets these specifications for accelerated stability testing.
How long does a typical multi-point humidity calibration cycle take?
A 5-point cycle (3 temperature setpoints × 2 humidity levels each) with 20-minute stabilization at each point takes 2.5–3 hours. Internal shelf design allows simultaneous validation of 6–12 sensors, making this efficient for production QA workflows.
What maintenance does the humidity system require?
Drain accumulated condensate every 1–2 weeks depending on cycle frequency. Saturated salt solutions (if manual humidity calibration is used) should be refreshed monthly. Automatic humidity generation systems (newer models) require distilled water top-up weekly and filter replacement every 6 months.
