An accurate, single-port Pulsation and Vacuum Tester using the same measurement system as the DairyTest range. A simple 3-digit display with function indicators is great for quick checks of Pulsator operation and vacuum levels. All Pulsation parameters are available in both % and ms where appropriate. Long battery life a fast operation make MiniTest and ideal unit to keep in the truck. Uses InnovAg’s digital calibration system with no manual adjustments for excellent long-term accuracy.

The MiniTest is a handheld single-port digital instrument for testing vacuum supplies and pulsators in dairies.

With a large, easy-to-read 3-digit display, MiniTest uses the same high-accuracy analysis as our other testers, but in a smaller, lighter, lower-cost format.

The MiniTest is intended for use by personnel with technical knowledge of dairy operation as an accessory to a professional test kit; for example, for bench-testing of pulsators or to do a quick check on the dairy’s performance. It is ideal for veterinarians and field professionals who need to check dairy operation without the cost or complexity of a fully featured tester.

It has only a single vacuum port and cannot be connected to a PC or printer.

Why is the VAC/PUL light flashing?
The batteries are getting low.

How do I reset the MiniTest's zero?
Turn the unit on. Select VAC mode.
Press and hold the VAC/PUL key. After about 5 seconds both the VAC or PUL lights will turn on. Do not release the key yet. Press both the I/O and the play key. The PUL light should go off indicating the manual zero has been accepted. Release all keys and check the display shows 0.0.
