Humidity is an important factor in many environments, ranging from storage warehouses to manufacturing facilities. The level of humidity in the products can affect the growth of mold and mildew, as well as the rate at which objects rust or degrade. Thus, it is important for manufacturers of different industries to test the humidity present in the products. Below we have listed the applications of humidity testing chambers for different industries: Pharmaceutical industry: A humidity testing chamber is a temperature and humidity-controlled environment used to test the durability of materials and products in order to ensure their quality and performance in real-world conditions. By subjecting materials and products to different levels of humidity and temperature, manufacturers can determine how well they will stand up to long-term exposure and use. In the pharmaceutical industry, the manufacturers can make use of humidity testing chambers to test the effect of humidity on the products like medicines and drugs. Rubber Industry: The use of humidity chambers in the rubber industry is a common practice in order to achieve the desired level of humidity and ensure that the correct level of the product will be delivered to the customers. This helps to ensure that the finished products will have the correct level of hardness and flexibility. In addition, using a humidity chamber can also help to reduce the risk of defects in the finished product. The rubber manufacturers can easily make use of this lab testing instrument to ensure the accuracy and reliability of test results. Plastic industry: A humidity chamber is a key lab testing instrument that is used to test plastic products. By controlling the level of humidity in the air, it helps to ensure that products are made with consistent quality. This type of chamber is often used in the plastic product manufacturing industry in order to prevent the warping or deforming of products during the production process. By controlling the humidity levels within the chamber, manufacturers can ensure that their products maintain their desired shape and size. Presto Stantest, one of the famous manufacturer in the world of testing instruments, offer high-quality of Humidity Chambers with a different temperature setting option and relative humidity to access the effect of different weather conditions on products. The instruments are designed as per the standards ASTM D1776 / D1776M – 15 and BS 950 Part 1 (D 65) which ensures the accuracy and reliability of test results.

WIST -Insect rearing chambers are equipped with microprocessor-based temperature controllers, each offering dual digital displays (actual value and set value), straightline PID control, audible high/low alarms, and remote alarm connections. Our reach-in chambers employ thermoelectric cooling, and a high capacity circulation system to ensure uniform air distribution and exceptional uniformity from top to bottom throughout the chamber. Thermoelectric cooling offers exceptional reliability, completely eliminating refrigeration leaks and compressor failures, with a mean life expectancy of more than 15 years per unit. Standard temperature range is 18c-32, but extended temperature ranges available upon request. We also offer a 80c high temp decon cycle to kill of mites or other parasites.

Very precise humidity control is also available with control  of +/-.5% RH by employing an Ultrasonic humidity system. Ultrasonic humidification provides increased energy efficiency and precision in humidity control compared to traditional steam boilers.

Stability Tests are an important step in the development of new drugs and pharmaceutical substances and an indispensable element in the licensing process defined by federal regulating authorities. However, these tests are just as important for safeguarding the quality of the product within the framework of quality assurance.

Together with committees from the pharmaceutical industry, experts from the licensing authorities (such as the FDA) have developed the ICH Guidelines for the harmonization of stability tests. These guidelines define standardized storage and batch evaluation as well as the time sequence of the required analytic tests.

According to the ICH Guideline Q1AR2, stability tests have to be performed under defined climatic conditions in order to provide evidence of the stability of active substances.

WIST offers a range of test chambers to meet these regulatory requirements as well as stability testing requirements for other industry segments of Cosmetic, Food & Beverages, etc.

We offer a centralized solution across all ICH conditions of real-time, intermediate, accelerated & semi-permeable study conditions along with a state-of-the-art 21 CFR Part 11 ready software that provide tools for viewing, trending, alarm management, audit trails, MKT & many other such features.
