Core offering

ISOTECH designs, manufactures, and sells precision temperature calibration instruments and standards, including primary standards (SPRTs, fixed-point cells, thermometry bridges), industrial dry-block and fluid-bath calibrators, handheld and benchtop thermometers, and specialized probes. The company also operates an ISO 17025 UKAS-accredited calibration laboratory providing traceable calibration services, plus I-Cal Easy software for documenting calibration data.

Product overview

Isotech is a manufacturer of precision temperature calibration and measurement solutions with over 45 years of experience. Their product portfolio spans from primary laboratory standards (SPRTs, fixed point cells, thermometry bridges like the microK², standard resistors) to secondary laboratory equipment (stirred liquid baths, cryostats, calibration furnaces) and industrial calibration tools (dry block calibrators, handheld thermometers like the TTI-10, portable liquid baths). The offering is organized around three tiers: Primary Standards for national laboratories requiring the highest accuracy, Secondary Laboratory for calibration labs needing low uncertainty from -200°C to 1300°C, and Industrial Calibration for portable solutions from -100°C to 1200°C. The microK² thermometry bridge and milliK precision thermometer serve as flagship measurement instruments, while the 4000 series dry block calibrators are the primary industrial calibration products. Supporting software includes I-Cal Easy for automated calibration, Icarus for ITS-90 calculations, and Cal Notepad for data logging. The company also provides ISO 17025 accredited calibration services from their UKAS-accredited laboratories.
