Our services assist organizations to maintain high-quality performance, meet regulatory requirements, and achieve precise calibration standards.


Pyrometer Calibration
Tempsens offers calibration of Non contact temperature sensors i.e. Infrared pyrometers traeceble to both national and international standards. Infrared thermometers can be calibrated at our NABL accredited laboratory, from 0ºC to 2900ºC utilizing state-of-the-art blackbody sources.

Furnace Calibration / Thermal Survey / Temperature Uniformity Survey
Tempsens Calibration Centre offers calibration of wide ranges of Furnaces at site and at our lab.

Consultancy Services

Training and Workshops
Tempsens yearly conducts Technical workshops both in house (for its employees) and for customers in the field of temperature measurement and related sub fields. We believe that regular training not only increases the skill level but it also ensures that the gained skill helps in improving the output which in turn advances the business to newer horizons.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Services.
Pyrometer calibration is performed against pyrometer calibration standard traceable to ITS-90 (International Temperature Scale of 1990), using NABL-accredited blackbody sources. Tempsens follows calibration procedures aligned with ISO/IEC 17025 laboratory accreditation requirements.
Most industrial applications require pyrometer calibration at least once per year. High-criticality processes such as steel casting, glass melting, or pharmaceutical manufacturing may require calibration every 3–6 months or after any significant process change, instrument repair, or impact event.
Pyrometer calibration standard refer to the reference traceable sources and measurement protocols used to verify instrument accuracy. These include blackbody radiation sources calibrated against national measurement institutes (NMIs), transfer standard pyrometers, and documented uncertainty budgets all aligned with ITS-90 and ISO/IEC 17025 requirements.
Furnace calibration involves two processes: a system accuracy test (SAT), which measures total error in the temperature control loop, and a temperature uniformity survey (TUS), where calibrated thermocouples are placed at defined positions throughout the chamber to verify heat distribution.
Heating element ageing, sensor drift and calibration error occur throughout time and if you do not have a regular thermal survey and SAT verification performed at some point in time, these errors compound becoming a serious safety issue for the operation of the furnace. Regular furnace calibration prevents out-of-spec processing, product rejections, and non-conformances during audits.
Under AMS 2750H/CQI-9, a temperature uniformity survey is typically required quarterly or semi-annually depending on furnace class, while a system accuracy test is required monthly. Frequency also depends on furnace usage intensity and the applicable customer or process standard.
The primary standard is AMS 2750H. Furnaces are classified into Class 1 through Class 6 under AMS 2750H, each with defined temperature uniformity tolerances. Tempsens furnace calibration service supports compliance across all these frameworks.
