Humidity Chamber Manufacturer in India: Precision in Moisture Testing

When it comes to testing products under controlled moisture and temperature conditions, whether for pharmaceuticals, electronics, materials, or packaged goods, a humidity chamber is indispensable.These chambers simulate varied relative humidity (RH) and temperature profiles to verify how products handle real-world environmental stress.In India, as regulatory requirements become more stringent and quality assurance demands rise, the role of a reliable humidity chamber manufacturer is critical.

What Is a Humidity Chamber & Why It’s Important

A humidity chamber (also called a temperature-humidity chamber) is an environmental test enclosure where both the temperature and the relative humidity levels are precisely controlled.This kind of chamber is used to simulate conditions such as damp climates, moisture stress, and condensation cycles, helping manufacturers test product durability, shelf life, and performance under humidity stress.

Such chambers find applications in:

Pharmaceutical and biotech industries (e.g., stability testing under moist conditions, a core requirement fulfilled by any reputable Stability chamber manufacturer in India)

Electronics and semiconductor sectors (moisture stress, corrosion, insulation testing)

Packaging and materials (how packaging or components hold up in high humidity)

Consumer goods, automotive, aerospace (verifying performance / reliability under humid environments)

Without a well-designed humidity chamber, your products or formulations might fail when exposed to humidity in the field, and your test results may lack reproducibility.

Key Design & Technical Features to Look For

A good humidity chamber must balance temperature control and humidity control, often in tight tolerances.First, the chamber should maintain temperature with high precision—while adjusting humidity, heat can shift the thermal balance, so strong control over both variables is essential.Relative humidity accuracy typically ought to stay within $pm$2 % RH (or similar), and the uniformity across the chamber should be tight so that all sample locations see essentially the same conditions.

The internal construction should use high-grade stainless steel (mirror or dull finish) for corrosion resistance and ease of cleaning, while the external body might be powder-coated or stainless depending on model. Heavy-duty door hinges and latches ensure the door seals uniformly over years of use, preventing leaks or fluctuations. A multi-pane viewing window (or double-door insulation) helps minimize condensation and lets users observe without disturbing the interior.

Control systems (PLC, PID, HMI) are essential: you want intuitive interfaces for setting temperature and humidity cycles, along with sensors (for example 4–20 mA humidity sensors, Pt100 for temperature) that provide accurate feedback. Auto-tuning features help the system stabilize quickly after disturbances.Data logging is important—not just recording temperature and RH, but door open/close events, alarms, power cycles, and more.Connectivity via USB, Ethernet, or remote monitoring makes audits and validation easier.

Safety features are equally critical: alarms should alert in case of deviations in temperature or RH, power failure, low water level, door-open status, or cutoffs for extreme conditions. For advanced setups, optional standby systems (humidifier backups, refrigeration backups), GSM alert modules, or security systems can add robustness.

Why India Is Becoming a Good Base for Humidity Chambers

India is emerging as a competitive manufacturing base for test chambers, including humidity chambers, because of the following:

Growing industrial and regulatory demand — With more pharmaceutical, electronics, and materials firms needing compliance-grade test facilities, demand for such chambers is rising.

Cost-efficiency — Domestic manufacturing reduces import duties, shipping costs, and lead-times, offering good value.

Local support & service — Having a local Humidity chamber manufacturer in India means faster after-sales support, calibration, spare parts, and service calls.

Flexibility & customization — Indian manufacturers, from bench-top specialists to a large-scale Walk in stability chamber manufacturer in India, are often more open to tweak designs (size, RH/temperature ranges, door layout) to customer needs.

Standards alignment — Companies are aligning their chambers to international standards (e.g. for humidity testing) and offering features for audit trails, validation, and regulatory compliance.

These advantages make sourcing a humidity chamber from a competent Indian manufacturer a smart choice for labs, firms, and test houses.

What Kesar Control Systems Offers in Humidity Chambers

Kesar Control Systems is positioned as a trusted humidity chamber manufacturer in India. Based on product details available on their website, here’s what their chambers typically include:

Their chambers are fabricated with CNC precision, with interiors made of high-grade stainless steel (mirror or dull finish) and exteriors either in stainless steel or GI powder-coated, depending on model. The design incorporates multi-pane viewing doors (to prevent condensation and allow observation) and heavy-duty hinges and latches to maintain a uniform seal. Adjustable stainless steel shelves allow flexibility in sample arrangement.

In terms of performance, the chambers aim for tight tolerances: temperature variation of 2–3 °C and RH variation of 2–3 % (i.e. high stability and uniformity). The control systems are usually PLC- or PID-based, with 7″ HMI touchscreen panels, auto-tuning, and password protection. Sensors are typically 4–20 mA humidity sensors and Pt100 temperature sensors. The system supports data storage and transfer via USB or Ethernet, logging parameters like setpoint (SV), process value (PV), door events, and power cycles.

Safety and alarm systems include high/low alerts for both temperature and humidity, cutoffs for extreme values, low water-level protection, door-open alarms, power-failure alerts, and auto-changeover for standby systems. Optional features include standby humidity or refrigeration systems, security/GSM alert systems, 21 CFR Part 11–compliant software, etc.

Kesar lists typical technical specifications as:

Temperature range: 20 °C to 60 °C

Humidity range: 40 % RH to 95 % RH

Accuracy: ±0.2 °C & ±2.0 % RH

Uniformity: ±2.0 °C & ±3.0 % RH

They offer various models (e.g. KGOS-90, KGOS-227, KGOS-325, KGOS-400, KGOS-500, KGOS-600, KGOS-800, KGOS-1000) with internal/external dimensions and tray capacities listed.

Tips for Selecting a Humidity Chamber

When choosing, keep in mind:

Check validation / performance data, especially RH uniformity and stability across the chamber interior.

Ensure the sensor types and quality (humidity sensors, temperature sensors) are reputable.

Ensure the control system supports data logging, audit trails, and connectivity for compliance.

Confirm service network and spare parts availability in your region.

Evaluate upgrade options (standby systems, GSM alerts, advanced software).

Match capacity to your throughput and sample sizes, leaving margin for future growth.
