Temperature Measurement Instruments and Support

Isotech is a world leader in temperature metrology. With over 30 years of experience in the design, manufacture and practical use of precision temperature calibration standards, Isotech is an experienced supplier for national labs and field calibration technicians world wide.

Customers include primary laboratories such as NIST & NRC as well as accredited laboratories, defense organizations, pharmaceuticals, and Oil & Gas companies.

In addition to our own products, Isotech is the exclusive service and distribution center for all ASL products in North America. ASL is the world leader in AC thermometry bridges and digital thermometers

You would think that supplying the most respected temperature measurement instruments to the most highly respected institutions, organizations and laboratories would keep us too busy to give advice on how best to implement a pressure calibrator or hand held precision thermometer. But helping our customers get the most out of something like a hydraulic hand pump or dry block calibrator is our meat and potatoes. It's our bread and butter. After all, the Isotech staff of experts has years and years of combined technical know-how to share with you, and so nothing pleases one of us more than a question from any client, big or small, about deadweight testers, thermocouple referencing, automating temperature calibration baths, stem conduction and light piping, and on and on. Read our articles for more information and don't hesitate to contact us, no matter what you need to know. We look forward to hearing from you.

MicroK Precision Thermometer

The New MicroK Precision Thermometer Offers Unrivalled Accuracy and Stability & Versatility
Isotech has introduced a new type of precision thermometer, which will set new world standards for accuracy and stability. Designed for a wide range of highly accurate industrial and scientific calibration applications, the MicroK uses a completely new measurement technique to achieve accuracies better than 0.4 parts per million(ppm)-equivalent to 0.0004 °C (0.4mK)-when used with a standard platinum resistance thermometer (SPRT). The MicroK is the only thermometer in the world which will work to this precision with all three commonly used sensors; plantinum resistance thermometers (PRTs), thermocouples and thermisters.

F100 Precision Thermometer

The New high performance handheld 2-channel thermometer for Pt100 and Thermistor probes
If you're looking for a step up in measurement accuracy with a battery powered, handheld thermometer, the F100 is for you. Our F100 can handle all your needs, with accuracies and resolutions normally associated with a bench top thermometer. Two inputs give you direct temperatures from Pt100 or Thermistor probes, or you can display the temperature difference between them. You can log measurements directly to memory or, if you prefer, use the USB port to control and data log with your PC. The F100 will display for you a statistical analysis of your measurements, with average value, min and max values and standard deviation. Most instruments require you to enter calibrated probe data into memory to optimise measurement accuracy, which can mean a lot of data entering if you change probes regularly. With ASL's SMART connector on your probes, you only need to store the data once — in the connector! The calibration data stays with the probe — permanently.
