Choosing a pressure flow process measurement calibrator usually means balancing price against condition. The four units here range from $200 to $450, and their conditions vary from for-parts to used. One offers a complete dead-weight tester, another is a handheld calibrator, a third is a hand pump for pressure and vacuum, and the last is a clean used gauge calibrator. The right choice depends on whether you need a bench reference, a field handheld, a pressure/vacuum source, or a ready-to-use gauge calibrator.

Decision matrix
- If you need a complete calibration assembly for a bench, the AMETEK Mansfield & Green RK-300 includes a weight set, hoses, and fittings, but it is listed as untested and for parts.
- If you want the lowest listed price in this group, the T203629 Ametek Jofra HPC600 is a handheld calibrator with test leads and a case, but it only showed a scrambled screen when powered on.
- If you need a pneumatic pressure and vacuum source for hand operation, the Druck SI Pressure TP1-40 is a used unit with a 29 inHg vacuum to 600 psi range and strong seals.
- If you want the cleanest used gauge calibrator in this spread, the Fluke 700G07 has the screen plastic still on and a like-new look.
Product notes
AMETEK Mansfield & Green RK-300 Pneumatic Pressure Tester Dead Weight Calibrator
The RK-300 is a full dead-weight calibrator rather than a simple gauge tester. The package includes a weight set, braided stainless hoses and fittings, inlet/outlet controls, a high/low range selector, a bubble level, and a carrying case marked with AMETEK and Nova Chemicals. That makes it a tempting centerpiece for a bench setup if you are prepared to inspect and repair vintage equipment. The obvious limitation is that it is listed as for parts or not working and untested, with no functional guarantee. Before relying on it for process measurements, you would need to check the weights, seals, and hoses carefully. At $349.99, it sits between the handheld unit and the Fluke in price, but its role as a dead-weight reference is completely different.
T203629 Ametek Jofra HPC600 Handheld Pressure Calibrator HPC600010CG
The HPC600 is the least expensive option here at $200.00, and it comes with test leads, connectors, and a carrying case. That makes it a candidate for someone who wants a handheld calibrator project or needs spare parts from a known Ametek Jofra model. The problem is that when powered on with fresh AA batteries, the screen remained scrambled, and there is visible evidence of previous battery leakage in the compartment. It is listed as for parts or not working, so treat it as a repair candidate rather than a calibrated instrument. The approximate 17x9x4-inch unpacked size and 5-pound weight give you a sense of the physical footprint, but the inability to boot means you would need diagnostic skills to bring it back to service.
Druck SI Pressure TP1-40 Pneumatic Hand Calibration Pump Base
If your setup already has a reference gauge, the Druck TP1-40 could be the missing pressure/vacuum source. This used hand pump holds vacuum without bleeding down and has strong internal seals. Its pressure range is 29 inHg vacuum up to 600 psi pneumatic pressure, and the dual-action selector switches smoothly between pressure and vacuum modes. The fine-adjustment vernier also turns well. The base format means it is the pump part of a calibration system, not a full calibrator, so you would pair it with a separate reference instrument. At $241.99, it costs more than the HPC600 but offers a functional, metallic, professional-grade pump with no internal plastic parts. Minor scuffs and industrial wear are the tradeoff for its used condition.
Fluke 700G07 Pressure Gauge Calibrator Super Clean
The Fluke 700G07 is the top of this price spread at $450.00, and its name points to its main selling point: a super clean used example. With the plastic still on the screen and a like-new look, it is the cleanest option in the group. It is a used single unit, which is consistent with a calibrator purchase rather than a kit. The limitation is the price: it is $250 above the HPC600 and $108 above the RK-300, so you are paying for a cleaner used unit rather than a lower entry cost. If you need a pressure gauge calibrator and have room in the budget, this one avoids the for-parts risk found in the two lower-condition units.
Final recommendation by use case
- Bench project or full dead-weight setup: AMETEK Mansfield & Green RK-300.
- Low-cost handheld repair candidate: T203629 Ametek Jofra HPC600.
- Functional pressure/vacuum hand pump: Druck SI Pressure TP1-40.
- Ready-to-use used gauge calibrator: Fluke 700G07.
Before you buy, match the unit's condition to the work you need it to do. A for-parts calibrator can be a money trap if it cannot be repaired, while a clean used unit may be worth the higher listed price when you need a working reference.
