Why Monitor Humidity as Well as Temperature?

Temperature alone doesn't tell you whether a storage area is safe. Relative humidity (%RH) measures how much moisture the air holds compared with the maximum it could hold at that temperature, and it affects many products directly:

• Medicines: tablets, capsules and powders can absorb moisture, changing dissolution, stability and shelf life.
• Packaging and labels: cartons soften, labels peel and blister packs can be compromised.
• Food: high humidity encourages mould and spoilage; low humidity dries produce.
• Electronics and documents: condensation causes corrosion; very dry air increases static discharge.

Because humidity changes with temperature (cooling air raises its relative humidity), recording both together gives the full picture, including the risk of condensation.

How a Temperature and Humidity Data Logger Works

1. 01

   Sense. A temperature sensor and a humidity sensor (usually a capacitive polymer sensor) measure the surrounding air.

2. 02

   Record. Readings for both are stored with a timestamp at your set interval, from every few seconds to every few hours.

3. 03

   Alert. Separate high and low limits for temperature and humidity trigger alarms on the device or, for wireless models, by SMS, email or app.

4. 04

   Report. Data is downloaded as a PDF or CSV report by USB, or viewed live on a cloud dashboard for wireless models.

Typical Temperature and Humidity Requirements

These are typical ranges. Always follow your product labels, stability protocols and quality procedures. India falls in ICH climatic zone IVb (hot and very humid), which is why 30°C/75% RH is the standard long-term stability condition for products intended for the Indian market.

What to Check in a Temperature and Humidity Data Logger

Where Temperature and Humidity Data Loggers Are Used

• Pharma warehouses and distributors: controlled room temperature and humidity storage for GDP compliance.

• Stability chambers: ICH stability studies at long-term and accelerated conditions.

• Cleanrooms and production areas: GMP environmental monitoring.

• Hospitals and pharmacies: medicine stores and dispensing areas.

• Laboratories: sample storage, reagent rooms and controlled environments.

• Food and grain storage: preventing mould, spoilage and moisture damage.

• Archives, museums and libraries: protecting documents and artefacts.

• Electronics and server rooms: avoiding condensation and static.

How to Check a Humidity Sensor

Between calibrations, you can check whether a humidity logger is drifting:

1. Compare with a reference. Place the logger next to a recently calibrated reference instrument in a stable environment and compare readings after they settle.
2. Use saturated salt solutions. Sealed containers with specific salts hold a known humidity (for example, sodium chloride at about 75% RH). Leaving the logger inside for several hours shows whether its reading matches.
3. Record and act. Log the check. If the difference exceeds your tolerance, send the logger for calibration or replace the sensor.

These checks don't replace formal calibration, but they catch drift early.
