InnoCal provides quality calibration service for all styles of
thermometers with our accredited (ANSI/ISO/IEC 17025:2005)
temperature calibrations. From liquid-in-glass thermometers
to infrared meters, our laboratory will provide you with
superior service and thorough documentation to support
your quality requirements.
All certifi cates are NIST-traceable unless otherwise
stated. Accredited certifi cates with calculated uncertainty
measurements are also available for many instrument
parameters. Also, for additional points or custom selection
of points, please call our technicians at 866-INNOCAL
(866-466-6225) for more information. Because when
quality matters, choose InnoCal, the Choice of Quality!
Liquid-in-Glass Thermometers
Ensure the accuracy of your ASTM, SAMA thermometers
Designed by the Grand Duke of Tuscany, Ferdinand II in 1654 by using alcohol in a sealed
tube. Liquid-in-glass thermometers continue to use mercury, alcohol, or spirits and are
a preferred method for many ASTM and SAMA tests today. The unique characteristics
of wide range, precision, repeatability, and quick response create a unique challenge for
the metrologist when performing these calibrations. InnoCal’s highly-trained technicians
perform calibrations within a controlled environment using high-precision Standard
Platinum Resistance Thermometers (SPRTs) in calibration baths.
Testing range from –80 to 300°C (–112 to 572°F)
Calibrated at specified number of points equidistant across the range of the instrument,
and include a zero-degree measurement (if thermometer includes zero on its scale)
Direct-comparison measurements to uncertainties as low as ±0.03°C + 1/4 of the
instruments’ resolution at a 95% confidence level
Calibration reports include measured data, emergent stem corrections, and ice-point
references as required to meet the most stringent quality and scientific requirements
Thermo-Electric Thermometry
The 1800’s saw a revolution in temperature measurement. Industrial needs for accurate, repeatable, and flexible designs not suitable
for other types of instrumentation had physicists working hard developing new methods of measuring temperature. The introduction of thermocouples, resistance temperature detectors (RTDs), and thermistors offered the solution to meet a wide array of applications.
InnoCal’s highly trained technicians use direct comparison, electronic simulation, or resistance measurement methods, and perform
calibrations using NIST-traceable primary or secondary standards. We are able to perform electrical simulation calibrations on Type T, J, E, K, S, R, B, C, N, and PL thermocouple meters, as well as RTD and thermistor meters from -270 to 2316°C at uncertainties as
low as (K=2) ±0.21°C +0.0001/°C. Our direct comparison methods—utilizing precision SPRT’s, baths, chambers, or dry blocks, allow us
to perform measurements from -80 to 1000°C at uncertainties as low as (K=2) ±0.018°C. Our calibration reports include measured data,
coeffi cients, and ice-point references (if required) to meet the most stringent quality and scientific requirements.
Thermocouples
InnoCal services all styles such as bare wire, sheathed, grounded, ungrounded, or exposed
junction, as well as the many different types of thermocouples such as Type J, K, T, and E.
Testing range from -80 to 1000°C (-112 to 1832°F) for probes and systems, -270 to 2,316°C (-454 to 4200°F) for meters
Tested against a NIST-traceable standard and the certificate indicates
“As Found/As Left” test data
Tested at four points equidistant across the range of the instrument, and calibration
automatically includes a zero-degree measurement as a no-charge fifth test point.
Resistance Temperature Detectors (RTDs)
RTDs are more accurate and stable than thermocouples, but cannot be used to measure
extremely high temperatures.
Testing range from -80 to 1000°C (-112 to 1832°F) for probes and systems,
and -200 to 1000°C (-328 to 1832°F) for meters
Tested against a NIST-traceable standard and the certificate indicates
“As Found/As Left” test data at multiple temperature test points
Tested at four points equidistant across the range of the instrument, and calibration
automatically includes a zero-degree measurement as a no-charge fifth test point.
Thermistors
Based on the principle that metal oxides change resistance with a change in temperature,
thermistors have excellent accuracy over the biological or ambient temperature ranges when compared to thermocouples or RTDs. Response times are generally faster than RTD probes.
Testing range from -80 to 150°C (-112 to 302°F) for meters, probes, and systems
Tested against a NIST-traceable standard and the certificate indicates
“As Found/As Left” test data at multiple temperature test points
Tested at four points equidistant across the range of the instrument, and calibration
automatically includes a zero-degree measurement as a no-charge fifth test point
Infrared (IR)
The actual inventor of the infrared thermometer is lost to history. But we do know
that in 1884, Austrian physicist Ludwig Boltzmann showed how Josef Stefan’s
empirical Black Body Radiation Law, formulated in 1879, could be derived from
the physical principles of thermodynamics. In the years that followed, many other
physicists continued to refine the technology leading to today’s advanced infrared
thermometers.
Given the convenience and versatility of IR thermometry (surface noncontact
temperature readings), it’s easy to understand why this technology is very popular
and used in many industries. Our calibration reports include measured data, field
of view and emissivity corrections (if required) to meet the most stringent quality
and scientific requirements.
Testing range from –12 to 500°C (10 to 932°F)
NIST-traceable infrared calibrations performed by using
black-body calibration sources with defined emissivities
Some hand-held IR instruments today not only provide the non-contact ability, but
also have a port to allow connection of a contact probe such as a thermocouple.
InnoCal provides calibration service to both of these methods, the IR meter itself,
the probe, or the system (meter and probe together). For complete assurance, we
recommend system calibration. Note: IR calibration is not accredited.
Bimetal or Dial Thermometers
Found in many applications, these thermometers offer a quick and convenient
method for measuring temperature either at the surface of a solid material
or under the surface with a penetration tip. Despite the relatively simple
technology or application, InnoCal understands that calibration for these
instruments can be just as important as any of the most sophisticated
temperature meters.
Testing range is from –80 to 1000°C (–112 to 1832°F)
Tested at three points equidistant across the range of the instrument—
calibration automatically includes a zero-degree measurement as a
no-charge fourth test point
ISO 17025 Accredited certificates are available for many measurement parameters. Call our experts or view our Scope of Accreditation for more information.
