Dwyer Instruments, LLC d/b/a DwyerOmega products

This BB-4A is a blackbody temperature reference source which is adjustable over the range from 100 to 982°C (212 to 1800°F) and accurate to ±1°C, ±0.25% rdg. It has a built-in digital temperature controller to provide accurate, stable temperatures as well as to provide the temperature readings of the cavity. The heated cavity provides a target of known temperature and emissivity, and virtually any infrared pyrometer with a spot size diameter less than 22 mm (0.88") can be calibrated. The compact, portable design allows for quick and easy calibration setups. Both models come standard with an RS232 computer interface which allows computer control of the setpoints for automatic test applications. A NIST traceable calibration certificate is also provided.

The BB702 Blackbody Calibrator is a high performance, rugged, portable calibrator for infrared pyrometers. The BB702 has a range from Ambient +10 to 215°C (Ambient +20 to 420°F) with an accuracy of ±0.5°C, ±0.25% rdg. The unit provides a heated target plate of known temperature and emissivity. Virtually any infrared pyrometer with a spot size diameter of 63.5 mm (2.5") or smaller can be calibrated. Both models come with an RS-232 computer interface which allows computer control of the setpoints for automatic test applications. An NIST traceable calibration certificate is also provided.

The BB703 is a high performance, rugged, miniature blackbody calibrator. It is used for infrared pyrometer calibrations with a temperature range of Ambient +10 to 400°C (Ambient +20 to 752°F). With its unique miniature design and built-in 29 mm (1.125") target aperture, the BB703 is an ideal and economical infrared calibrator for any laboratory or field service application. An NIST traceable calibration certificate is also provided.

The BB701 Blackbody Calibrator is a high performance, rugged, portable calibrator for infrared pyrometers. The BB701 Hot/Cold model has a range of -18 to 149°C (0 to 300°F). The BB701’s ability to provide a stable, repeatable cold calibration point allows the user to calibrate or test most infrared pyrometers quickly and accurately without having to prepare an ice bath. The target plate has a known emissivity, enabling the user to calibrate virtually any infrared pyrometer with a spot size diameter of 63.5 mm (2.5") or smaller. Both models come with an RS-232 computer interface which allows computer control of the setpoints for automatic test applications. An NIST traceable calibration certificate is also provided.

This economical blackbody is a benchtop reference source for long term repeatability measurement of laboratory sensors.

The BB704 is a blackbody temperature reference source which is adjustable over a range of 100 to 398°C (212 to 750°F) and accurate to ±0.8°C (±1.4°F) of the indicated temperature. It has a built-in digital temperature controller to provide accurate, stable temperatures as well as to provide the temperature readings of the target plate. The heated cavity provides a target of known temperature and emissivity, and virtually any infrared pyrometer with a spot size diameter of 102mm (4") or smaller can be calibrated. The compact, portable design allows for quick and easy calibration setups. Both models come standard with an RS232 computer interface which allows computer control of the setpoints for automatic test applications. A NIST traceable calibration certificate is also provided.

This BB705 is a blackbody temperature reference source which is adjustable over the range from 100 to 1046°C (212 to 1915°F) and accurate to ±1°C, ±0.25% rdg. It has a built-in digital temperature controller to provide accurate, stable temperatures as well as to provide the temperature readings of the cavity. The heated cavity provides a target of known temperature and emissivity, and virtually any infrared pyrometer with a spot size diameter less than 44.5 mm (0.88") can be calibrated. Calibration setups are easy with the BB705. An independent NIST traceable probe and high accuracy panel meter provide temperature reference information. Both models come standard with an RS-232 computer interface which allows computer control of the setpoints for automatic test applications. A NIST traceable calibration certificate is also provided.

Formulated to provide precise pH determinations, these buffer solutions which are standardized against N.I.S.T.-certified reference samples, are ideal for calibrating electrodes and pH meters. The buffers are color-coded to avoid error and accurate to within ±0.01 pH at 25°C (77°F). Each buffer contains a preservative/mold inhibitor and a shrink-sealed cap to prevent contamination and leakage. Temperature compensation charts are included with each buffer solution. The shelf life of the buffer solutions are 1 Year.
