Product Announcement from Micro Quality Calibration, Inc.

Temperature / Humidity / Chemical Calibration-Image

Micro Quality Calibration ("MQC") is at the forefront of the Metrology industry with a service offering and capabilities unmatched among its peers. Our A2LA ISO/IEC 17025-2005 accreditation mandates us to uphold the highest level of quality assurance, documentation, and accuracy so that you can rest assured your equipment will be serviced to the highest quality disciplines while our staff provides exceptional service and keeps you updated on your equipment.

Temperature is the world's most widely measured property. When measuring in a scientific, industrial or commercial use the temperature of a process must be measured and controlled definitively. As the industry continues to evolve, so does the search for new applications and more exacting temperature measurement and control solutions. MQC understands there is no substitute for repeatability, accuracy and temperature uniformity.

Furnaces and ovens require periodic inspection to assure the user of uniform temperature and heating throughout the apparatus to guarantee batch repeatability. MQC calibrates, inspects, tests and can certify your equipment to the highest accreditation in the industry with data. Testing is accomplished by measuring temperature in several locations throughout the furnace and monitoring temperature with thermocouples over time then recording findings according to AMS2750D specifications.

MQC has the ability to calibrate a broad range of thermocouple types and temperatures (-328ᵒF to 4,208ᵒF). Thermocouple type, insulation and probe construction will all have an effect on the measurable temperature range, accuracy and reliability of the thermocouple readings.

Always ensure that your measuring equipment does not limit the range of temperatures that can be measured. Resolution will directly relate to sensitivity. Low sensitivity (B, R and S) have a correspondingly lower resolution. Below are some general thermocouple types:

Type K (Chromel / Alumel) - 'general purpose' thermocouple. It is low cost and available in a wide variety of probes. Thermocouples are available in the -200°C to +1200°C range. Sensitivity is approx 41uV/°C.

Type E (Chromel / Constantan) - non-magnetic and well suited to low temperature (cryogenic) due to its high output (68uV/°C).

Type J (Iron / Constantan) - main application is with old equipment that cannot accept 'modern' thermocouples. J has limited range (-40 to +750°C) making it less popular than type K. The J types should not be used above 760°C as an abrupt magnetic transformation will cause permanent decalibration.

Type N (Nicrosil / Nisil) - high stability and resistance to high temperature oxidation. Less expensive than platinum (B,R,S) types.

Type B (Platinum / Rhodium) - suited for high temperature measurements up to 1800°C. Due to the shape of their temperature / voltage curve they give the same output at 0°C and 42°C. This makes them useless below 50°C.

Type R (Platinum / Rhodium) - suited for high temperature measurements up to 1600°C and have low sensitivity 10uV/°C. High cost makes them unsuitable for general purpose use.

Type S (Platinum / Rhodium) - suited for high temperature measurements up to 1600°C and have low sensitivity 10uV/vC. High cost makes them unsuitable for general purpose use. Due to its high stability type S is used as the standard of calibration for the melting point of gold (1064.43°C).

Thermocouple types B, R and S are all 'noble' metal thermocouples and exhibit similar characteristics. They are the most stable of all thermocouples, but due to their low sensitivity (approx 10uV/0C) they are usually only used for high temperature measurement (>300°C).

Most measurement problems and errors with thermocouples are due to a lack of understanding of how thermocouples work. Thermocouples can suffer from ageing and accuracy may vary consequently especially after prolonged exposure to temperatures at the extremities of their useful operating range. Common problems include: connection problems, lead resistance, decalibration, noise, common mode voltage, and thermal shunting.

Preparation

Our Electrical Laboratory not only uses the most advanced state-of-the-art equipment but is also environmentally controlled (both temperature and humidity are closely monitored 70°F with relative humidity not to exceed 40%) to give the highest degree of measurement uncertainty. Preparation of your precision measurement test equipment is just as important as the calibration. Preparation varies and is equipment specific.
