GENERAL DESCRIPTION
These microprocessor-based thermometers
allow temperature measurements using K-type
thermocouple probes. The non-linearity of the
temperature probe is linearized by the built-in
microcomputer. It also permits accurate compensation for drifts in the measurement circuit
and the reference junction.
Standard features include:
• display and clearing of maximum/minimum
temperature measurement
• reading hold
• memory entry (HI 9053 and HI 9055 only)
• low battery detection
Additional functions for HI 9053 and HI 9055
include:
• sound alarm with preset operating range
• display of constantly updated temperature
differential between stored and measured
values.
• selectable measurement range/resolution.
These functions are easily accessible through
the splash-proof membrane keypad.
Self-explanatory symbols are used to remind
the user of the operating mode or condition.
