The 9881 is a microprocessor based combined printing and data-logging thermometer. The unit is housed in a durable ABS plastic case with easy to use push buttons and a custom LCD display incorporating a backlight.
The printing thermometer measures temperature over the range of -200 to +1370°C with a resolution of 0.1°C/°F (-200 to +650°C) or 1°C/°F. The unit incorporates two thermocouple type K probe sockets, enabling the user to connect one or two probes with selectable readings of probe 1, probe 2 and a differential temperature reading.
The dot matrix printer prints directly onto thermo-paper, eliminating the need for an ink cartridge/ribbon. The thermometer can instantly print a reading or the user can store up to 99 temperature readings for printing out at a later date. The printing programme incorporates a real-time clock and calendar, allowing measurements to be date-stamped and personalised with up to a 14-character ID note.
The 9881 printing/data-logging thermometer can also be programmed to record temperatures at given time intervals, as often as once a second up to every two hours (7,200 seconds). The unit features a realtime clock and enough memory to store up to 4,000 samples/readings. The data-logger/thermometer incorporates a number of programmable parameters including the logging start time - immediate or time delayed.
Each 9881 printing/data-logging thermometer is supplied with two rolls of paper, two air wire thermocouple
probes and instructions for use.
