Key features • Calibrate up to four tri-clamp sanitary sensors per batch with ± 0.1 °C temperature display accuracy. • Covers a wide temperature range: 6109A: 35 °C to 250 °C • 7109A: -25 °C to 140 °C. • Stainless steel casing that withstands harsh cleaning solutions; it's easy to transport and maintain.
Widest temperature range available in a single dry-well • Combined range from –30 °C to 670 °C, one unit – two blocks • Two independent temperature controllers (hot and cold side) • Stability to ±0.02 °C • Multi-hole wells for calibrating up to eight probes simultaneously
To give you the widest temperature range available in a dry-well calibrator, we’ve combined two of our most popular units. The 9011 allows temperature probes to be calibrated from –30 °C to 670 °C in a single unit.
Ice-point reference without the ice • Bath-quality stability in a portable ice-point reference • Easy re-calibration for long-term reliability • Ready-light frees user’s time and attention • Solid-state cooling technology
Have you been thinking about buying a zero-point dry-well? Forget those ugly-looking units the competition makes. You can get a great looking and great performing zero-point dry-well from Fluke Calibration.
The 9101 has three test wells for inserting more than one probe at a time. All three wells are stable to ±0.005 °C. One well accommodates changeable inserts for varying probe diameters.
The P3200 models are available in single or dual piston formats for increased operating ranges. Units can be supplied in psi, bar, kgf/cm², and MPa. This robust instrument is highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control. Options PressCal software for pressure calculations and certificate generation Operating principle Deadweight testers are the high performance pressure standard for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly. Instrument base There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.
Piston/cylinder assemblies
The piston/cylinder assembly is the heart of each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure the precision and performance required for today’s demanding calibration requirements.
Weight masses
Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the high or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum. Gravity correction
Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.

If you’ve been using a dry well calibrator or dry block calibrator for field work, you know there’s a lot more to them than temperature range and stability. Size, weight, speed, convenience, and software are also significant.
A field dry well needs to be portable, flexible, and suitable for high-volume calibrations or certifications. If it's not, you’ll soon forget about the great stuff the sales rep told you and realize what you’ve really bought.
At Fluke Calibration, we use dry well calibrators every day in our manufacturing and calibration work, and we know what makes a dry well easy and productive to use—which is exactly how users describe our series of field dry wells. These dry wells work for you instead of the other way around.
