6 Channel contamination monitoring is now the standard with CM20

CORE TECHNOLOGY AT THE HEART OF EVERY CM20

The CM20 portable particle counter feature microprocessor controlled optical scanning for accurate contamination measurement and a calibration range from ISO 7 to ISO 24 with no counter saturation.

So how does the CM20 work ?

As an oil sample is drawn through the CM20, particles are measured by a photo diode as they pass across a window. A resultant capacitance value is then counted and stored in the CM20’s onboard computer in one of six channels, 2ľ, 5ľ, 15ľ, 25ľ, 50ľ or 100ľ (micron) according to particle size and the results displayed on the hand-held LCD display in the accepted ISO or NAS standards.

Because the CM20 connects directly to an hydraulic circuit, fast and accurate results and a quick response is assured with an ISO or NAS readout in 4 minutes that will give immediate notification of system problems to the operator.

Portable Particle Counters

Automatic Particle Counters (APC's), have been widely used for many years in the field of condition monitoring of hydraulic fluids. However it is only comparatively recently that APC 's have become flexible enough to enable the instruments to be taken out of the laboratory and used on-line in order to obtain the most credible form of results.

Unusually, the move from fixed laboratory use to portable field use has not been at the expense of accuracy of testing or flexibility of use, but has actually improved accuracy and has enabled the instruments to be used over a wide range of applications and situations, making them ideally suited to very varied military applications.

There is now a range of CM20 contamination monitors to select from. Each calibrated by accepted on-line methods and confirmed by ISO 4402 procedures and each offering unique features designed to meet the needs of specific applications. It has been proved time and time again that effective and regular use of CM20 will recover its initial investment in a matter of months.

One of the keys to effective contamination monitoring with CM20 is the comprehensive network of UCC distributors trained to provide rapid service support to users.

THE CM20 RANGE

CM20 '6 Channel'
Portable Particle Counter

The CM20 '6 Channel' monitor puts laboratory testing into the shade with its on board battery pack and 12V dc input socket it can test when and wherever required.

Microprocessor controlled optical scanning and LCD readouts identify particle quantities per 100 millilitres and with 6 channel analysis as standard a user can be sure of accurate results every time.

CM20 '6 Channel'
Data Entry Model

The CM20 '6 Channel' Data Entry monitor has the 32 character two line dot matrix LCD and full alpha numenc facility and, at the touch of a button, a data retrieval facility to select any or all of the tests from the 300 scrolling test memory With '6 Channel' measurement ->2ľ, >5ľ, >15ľ, >25ľ, >50ľ and >100ľ, analysis in a range from ISO 7 to ISO 24 (NAS 0 to 12 inclusive),on board printer and RS 232 download port this C M20 monitor represents the very latest specification.

CM20 '6 Channel'
Aggressive Fluids Model

The CM20 '6 Channel' Aggressive Fluids monitor with its red valve and handset buttons has been developed to be suitable for aggressive fluids such as phosphate ester based lubricants which are corrosive This required re-specification of CM20 internals such as EPDM oil seals In all other respects this CM20 is designed and specified to the same comprehensive standards as the data entry model.
