Pressure
Portable pressure gauges, transmitters, indicators, and related devices may be accepted when the requested range, medium, connection, accuracy, and reference capability fit the controlled shop matrix.
Ocala Shop Calibration
Bring the instrument to a controlled, familiar workspace.
MJM is developing an in-shop pressure and temperature calibration capability for suitable portable instruments. We define the requested points, tolerance basis, reference standards, readings, result, and turnover record before accepting the work.
Temperature
Portable temperature indicators, probes, switches, and related devices may be accepted when the range, sensor type, immersion needs, accuracy, and comparison method fit the controlled shop matrix.
Field and specialty work
Installed loops, field commissioning, mass, electrical, flow, analytical, high-accuracy, or accredited-scope needs require separate review and may be referred to an appropriate provider.
MJM QAAI oversight
A calibration record should explain what was measured and how the result is supported.
01 Identify
Instrument, serial or asset ID, range, condition, connection, requested points, tolerance, and intended use.
02 Control
Method, environmental conditions, reference standard, calibration status, points, repetitions, and tolerance basis.
03 Review
As-found readings, measurement result, uncertainty basis when applicable, pass/fail rule, adjustment authorization, and as-left readings.
04 Package
Certificate or service report, supporting data, deviations, limitations, reviewer, and customer turnover.
TECHNICAL LEARNING
Watch a controlled calibration workflow.
Select a measurement type to see a manufacturer demonstration. The equipment shown is representative; MJM confirms the applicable method, range, accuracy, reference, and record before accepting work.

Traceability belongs to the result
NIST explains traceability as a property of a measurement result supported by a documented, unbroken calibration chain, with each step contributing to uncertainty. A calibrated instrument alone does not establish every later result as traceable.
NIST traceability policyConditions and uncertainty matter
The method, operator, environment, reference equipment, and instrument under test can all contribute to a result. The record must state what MJM actually measured and the limitations that apply.
NIST calibration policiesISO/IEC 17025
ISO/IEC 17025 is used to assess testing and calibration laboratory competence, impartiality, and consistent operation. MJM does not claim accredited status or an accredited result unless the accepted scope explicitly establishes it.
ISO/IEC 17025 overviewAvailable ranges, accuracy or uncertainty needs, reference standards, environmental limits, methods, adjustment authority, accreditation requirements, and reporting expectations are confirmed before an instrument is accepted. No NIST endorsement is implied.
