In temperature calibration, the reference is only as good as the chain behind it: the probe, the readout, and the way the two are matched. A precise PRT read by the wrong instrument, or a readout paired with a probe outside its range, adds uncertainty exactly where the calibration is supposed to remove it.
Additel builds both halves of that chain: reference thermometer readouts and AccuMac reference probes. AV-TEK Consulting supplies the range with selection support and NIST-traceable calibration.
The Additel 286 combines a high-end reference thermometer, a data acquisition system, and an 8.5 digit multimeter in one instrument. It scans and records up to 82 channels at 10 channels per second, so a single unit can handle field calibrations and uniformity studies, and serve in the lab as a precision thermometer and 8.5 digit multimeter.
Where it fits: temperature uniformity surveys of chambers, furnaces, and baths, and multi-sensor calibrations where channel count and logging speed matter.
The Additel 282 brings reference-grade temperature measurement to a handheld format. Its two analog channels are designed for comparison measurements, such as calibrating a sensor under test against a reference probe, and Additel positions its accuracy on par with laboratory-grade thermometers.
The readout is only half of the measurement. AccuMac probes cover reference thermocouples, PRTs, and SPRTs across different temperature ranges:
Matching readout, probe type, and temperature range to your procedure is where most of the uncertainty is decided. AV-TEK Consulting helps select the right combination, quotes the complete setup, and provides NIST-traceable calibration so your reference standards stay traceable.
The ADT286 is a multifunction readout with data acquisition: it scans and records up to 82 channels at 10 channels per second and includes an 8.5 digit multimeter. The ADT282 is a handheld dual-channel readout designed for comparison measurements.
The AM1210 Type S thermocouple covers 0 °C to 1300 °C. Among the PRTs and SPRTs, the AM1640/1660, AM1751, and AM1760/1762 cover -200 °C to 670 °C.
Yes. With up to 82 channels scanned at 10 channels per second, the ADT286 is designed for field calibrations and uniformity studies.
Yes. AV-TEK Consulting provides NIST-traceable calibration for reference readouts and probes.
