TestMate - TMU and TPM

The TestMate Monitoring Unit TMU series combines the advantages of the portable contamination measurement units with the measurement technology of the Testmate  Contamination Monitor (TCM) and TWS (Testmate  Water Sensor).

The TMU is a portable service unit and is designed for temporary measurement of solid particle contamination and water saturation in hydraulic systems.

The integrated pump and the hoses with test point connections, which are included with the TMU, allow operation on reservoirs, control circuits, and high pressure circuits.

The TPM is a portable particle counter with an integrated pump that can be used in-line to measure contamination levels of hydraulic fluid. Particles are measured at the 4, 6, and 14 micron sizes, with results available in ISO 4406 (1999) and SAE AS 4059, as well as several other options.

Various programming options are available, including the ability to activate or de-activate system functions when contamination reaches a user-specified level. It is equipped with a built-in printer to provide instant documentation and an RS-232 serial port for data transfer. A custom software package is also included for trend analysis on a PC. The unit’s robust packaging includes a folding handle which doubles as a stand to provide optimal viewing.
