Thermal Calibration is a comparison between standard and the measure thermal parameters of instruments. It not only includes comparison of parameters but also set span or offset adjustments & take into permissible range if facilities are available. Typically, the accuracy of the standard should be minimum three times the accuracy of the measuring device being tested (As per NABL norms) & we maintain more than this ratio by our accurate calibrator which calibrated by NABL Lab. In this calibration either externally thermal sources or electrical signals like mV, mA, V, Ω are given.
Temperature mapping is the process of mapping the differences and changes in temperature that occur within a single temperature controlled system due to influences like opening doors, proximity to cooling fans, personnel movement, and the quantity of products being stored at any given time. Temperature mapping locates the points of greatest temperature fluctuation and difference then analyses the causes of these. Temperature mappers create ‘worst case’ conditions to verify that a system maintains the correct temperature levels in all situations when influenced by external factors such as weather, and internal factors such as airflow restrictions and the operation of the Heating, Ventilation, and Air Conditioning (HVAC) systems. The effects of temperature difference are then calculated to make sure the system consistently meets the applicable industry standards.
Pressure Calibration is a comparison between standard and the measure pressure parameters of instruments. It not only includes comparison of parameters but also set span or offset adjustments & take into permissible range if facilities are available. Typically, the accuracy of the standard should be minimum three times the accuracy of the measuring device being tested(As per NABL norms) & we maintain more than this ratio by our accurate calibrator which calibrated by NABL Lab. In this calibration either externally pressured by hydraulic/pneumatic comparators or electrical signals like mA, mV, 24VDC, etc are given.
Temperature and humidity testing is conducted to determine the products ability to function either in it’s intended use, or in extreme environments. These tests are performed to determine the products ability to survive cold and hot temperature extremes coupled with extreme humidity. Testing can either be performed using temperature alone, or a combination of temperature and humidity.
Every product designer needs to understand their products’ end-use environment. Whether your product operates in an air-conditioned office or is used outdoors in extreme conditions depends on how far you need to test. Many industries and applications have temperature & humidity testing mandated by either regulations or industry standards.
Exposing your product to environmental stresses reduces the risk of field failures brought about by changes in climate. In particular, electronic products suffer degradation through exposure to higher temperatures, whilst metals and plastic suffer from humidity.
Basically, in insulation testing is applying a voltage (specifically a highly regulated, stabilized DC voltage) across a dielectric, measuring the amount of current flowing through that dielectric, and then calculating (using Ohm's Law) a resistance measurement. The resistance measurement is in megohms. This resistance measurement to evaluate insulation integrity.
Current flow through a dielectric may seem somewhat contradictory, but remember, no electrical insulation is perfect. So, some current will flow.
In on-site calibration services, services are provided on the customers’ location. It is most convenient calibration method for mass number of Instruments’ calibration. In this case, transportation cost as well as time is saved by using this method.
We are providing Thermal Calibration, Pressure Calibration, Elecro-technical Calibration, Humidity Testing, Insulation Testing & Temperature Mapping services on customers’ request.
