Precision Test Measures & Calibration Cans
A test measure is a handheld certified volumetric can used to verify the accuracy of fuel dispensers and small flow meters in the field. Lonetti manufactures test measures from 1 L to 50 L in 304 SS, built to OIML R120 and NIST Handbook 105-4, INTI-certified, used by inspectors in 47 countries.
What is a test measure?
A measured volume is dispensed from the meter under test and collected in the test measure can. If the meter reading matches the can's certified volume, the meter is accurate. Test measures are the standard tool for weights & measures inspectors verifying retail fuel dispensers.

What standards apply to test measures?
Lonetti test measures are built to OIML R120 accuracy classes 0.05 and 0.025, and NIST Handbook 105-4. Every unit ships with an INTI calibration certificate traceable to international metrology standards.
When do I need a test measure?
- Retail dispenser verification: Verifying fuel pumps at gas stations under weights & measures audit.
- Field meter inspection: Spot-checking turbine and PD meters during routine compliance visits.
- Refueling operations: Aviation, marine, and bulk-fuel delivery accuracy verification.
- Laboratory reference: Bench-scale calibration of smaller flow instruments in calibration labs.
Frequently asked questions about test measures
What is the difference between a prover tank and a test measure?
A prover tank is a large, usually stationary or trailer-mounted vessel (50 L–5,000 L+) used to calibrate industrial flow meters and bulk delivery systems. A test measure is a smaller, portable handheld can (1 L–50 L) used in field or retail settings to verify the accuracy of fuel dispensers and smaller meters.
What accuracy class do Lonetti test measures meet?
Lonetti test measures meet OIML R120 accuracy classes 0.05 and 0.025, depending on capacity. Each unit ships with an INTI calibration certificate traceable to international metrology standards.
Are custom volumes available?
Yes. Standard sizes are 1, 2, 5, 10, 20, 25, and 50 liters, but custom capacities and imperial-gallon sizes can be built to specification. Lead time is 4–8 weeks.
