- Multiple-hole inserts for compatibility with a wide range of probe sizes
Fast Calibration with Minimal Downtime
- Units are easy to calibrate without opening the case, reducing maintenance costs and downtime
- All units include a NIST-traceable calibration certificate at no additional charge
- Factory-tested for accuracy and reliability before shipment
Software Integration
Fluke’s Interface-it software supports:
- Set-point and ramp rate control
- Real-time temperature logging
- Electronic strip chart creation
- Thermal switch test automation with data collection
- Windows-based interface with intuitive graphical controls
Whether you need basic control or full automation, Fluke has a software solution ready.
Fluke 9103 – Low-Temperature Field Dry-Well
- Temperature Range: Down to –25 °C (actual, not below ambient)
- Stability: ±0.02 °C
- Display Accuracy: ±0.25 °C across full range
- Speed:
- Reaches 0 °C in 8 minutes
- Reaches 100 °C in 6 minutes
Key Advantage:
Many competitors advertise –45 °C below ambient, which only reaches around –20 °C. The 9103 delivers a true –25 °C in standard room conditions—no walk-in freezer required.
Insert Options:
Choose from four removable inserts to suit your calibration needs:
- Insert A: One well each from 1/16” to 1/2”
- Insert B: Two wells each of 3/8”, 1/4”, and 3/16” (ideal for comparison calibrations)
- Insert C: Six 1/4” wells for multiple probe calibrations
- Insert D: Three pairs of metric-sized wells
Fluke 9140 – Mid-Temperature Field Dry-Well
- Temperature Range: 35 °C to 350 °C
- Stability: ±0.05 °C or better
- Uniformity:
- 0.1 °C in small-diameter wells
- 0.4 °C in largest-diameter wells
- Speed: Reaches max temperature in 12 minutes
- Size: Weighs only 6 lbs, easily portable with one hand
- Display Accuracy: ±0.5 °C
For improved calibration accuracy, use an external thermometer alongside the built-in display.
Insert Options:
Three removable inserts available to accommodate various probe sizes.
