Any tool (flowmeter, thermometer, etc...) that is traceably calibrated to required specifications can be used with v-kit. For convenience NLG offer a fill range of v-kit approved "v-tools".
Yearly calibration is recommended or following repair if some damage has occurred to the tool. Tools can be calibrated locally (if traceable calibration is available) and NLG offer traceable calibration of all v-tools.
