Ecklund-Harrison Technologies Inc.

The Ecklund-Harrison pasteurize Process Monitor 4 (PM-4) is the next generation PU tunnel pasteurizer beer and beverage pasteurization monitoring computer. In response to your needs, we have eliminated the need to calibrate and recharge the internal battery. It is the first computerized pasteurization monitor that was offered to the brewing industry over 30 years ago. The PM-4 offers the utmost in ease of use and reliability today. The PM-4 is housed in a waterproof NEMA rated enclosure. The window in the housing cover allows for the display of operational data. This gives the user immediate results of the product run without having to interface to a computer. A water tight electrical connector allows for the attachment of interchangeable Precision RTD temperature probes. The PM-4 communicates with a computer using an IR (Infra Red) reader attached to a serial or USB port. The PM-4 utilizes extremely low power components and operates with a very high amperage hour rated internal battery. The PM-4 will operate hundreds of hours before battery replacement is needed. The PM-4 travels with the product through the tunnel pasteurizer. A product container (can or bottle) is placed in a sample basket and the temperature of the cold spot is monitored with a precision RTD temperature probe attached to the PM-4. A second precision RTD temperature probe monitors the ambient spray temperature. Product temperature as a function of time is measured and used to calculate Pasteurization Units (PUs). Spray and product temperatures, maximum cold spot temperature, and elapsed time are all recorded and saved in memory. To store a permanent record of the product run, the PM-4 may be interfaced to a Windows® based computer using the optional IR reader. Our Windows® compatible software provides the capability to store data, produce screen displays, and print graphs. The PM-4 software is very user friendly and easy to install.

*A PU derived from the Lethal Rate Curve, is logarithmically a function of time and temperature.
One PU will be delivered if 140 degrees F (60 Degrees C) is maintained for one minute.
PU's change with temperature by an order of magnitude (x10) for each 12.5 Degree F (6.9 Degree C) change in temperature and increase with increasing temperature.
