Ace instruments supplies data loggers and recorders for process temperature, pressure, vacuum, ph and flow. These are 8- and 16-channel instruments that can be configured to take inputs of rtd pt 100 sensors, any thermocouples, voltage or current [ma] signals. The instruments have a rs232/485 computer communication port and come with data logging/recording software for real time analysis and transferring data to excel sheet format.The data loggers and recorders have a direct printer port which can be connected to an 80-column dot-matrix printer without using a computer. The instruments can be programmed from the front keys to print the data of all 8-channels at any time interval. This means that the print time between successive printouts is user programmable from 5 secs to 9999 secs. The printout includes the date, time, channel number and its value. Additional features include universal input selectable from front key, i.E. Each channel can be independently configured for any kind of input. Thus, a single instrument can be used to record temperatures, pressure, vacuum, flow, ph, conductivity at different channels of the same instrument.
