These calibrators cover temperatures from –40°C to 650°C, deliver the performance you’ll only find in true lab standards, and come in a totally portable case. If your work involves ocean vessels, aircraft, or service trucks, these dry-wells were designed for you. The U.S. Navy purchases the Model 9007 on contract N00244-00-D-0100.

The Model 9007 Dry-Well covers –40°C to 140°C. No external cooling is needed, so you get –40°C in normal ambient. Set-point accuracy is ±0.15°C and stability is better than ±0.02°C.

For hotter temperatures, the Model 9023 Dry-Well extends from 35°C to 650°C. Heating time is only 45 minutes to 650°C. Set-point accuracy is ±0.3°C to 450°C and ±0.5°C to 650°C. Stability is better than ±0.08°C even at 600°C.

These dry-wells come with a unique NIST-traceable calibration at the full, six-inch depth of the well and at a three-inch depth for short probes. Coefficients for each calibration are stored in the dry-well and can be easily selected from the front-panel control buttons to match the length of the probe being tested.

Both models are encased in all-aluminum enclosures that are durable, waterproof, and meet the standards of MIL-T-28800. Each unit comes with both RS-232 and IEEE-488 interface connections. A wide variety of inserts are available covering probe widths from 1/16" (1.6 mm) to 7/8" (22 mm).
