GENERAL DESCRIPTION
These instruments are powerful and flexible thermometers, which can
take measurements using different types of thermocouple probes (K, J
and T), and have been designed using the latest microprocessor
technology to provide reliable and accurate high resolution measurements in a wide temperature reange.
Standard features include dual-level LCD (which allows continuous
displaying of High and Low temperature values), °C/°F selection,
HOLD function, auto-off capability, remaining battery life indication,
low battery detection, long battery life and two-year warranty.
HI 93542, HI 93552 and HI 93552R are two-channel thermometers,
ideal for monitoring two samples at once.
HI 93551N, HI 93551R, HI 93552 and HI 93552R offer additional
features, such as calibration of meter and probe at 0°C, backlit
display, and capability to store and recall a reading.
Moreover, the HI 93551R and HI 93552R models are equipped with
a serial port interface.
