HI 9056 performs temperature measurements using interchangeable K-type thermocouple probes.
HI 9057 performs temperature measurements with different types of thermocouples
(K - J - T). This meter is equipped with a key
that switches range from K-type to J-type or
T-type thermocouples.
The non-linearity of the temperature probe
is linearized by the built-in microprocessor,
in order to achieve a high degree of accuracy and resolution. Also the HI9056 accurately compensates for temperature drifts in
the measurement circuit and the reference
junction.
HI 9056 has two built-in K-type probe connectors. By simply pressing a button, the
meter switches between the two readings on
the display. A "∆T" button will display the
difference between the two probe readings.

Standard features include:
• Interchangeable probes
• Clear Liquid Crystal Display
• Two year Warranty
• Possibility of switching between the Centigrade and the Fahrenheit scale (for
HI 9057 only)
• HOLD function that freezes the reading
on the display (for HI 9057 only)
• HI-LO memory recall function (for HI 9057
only)
• Low battery detection.
All these functions are easily accessible
through the keypad.
Self-explanatory symbols are used to remind the user of the operating mode or
condition.
Hanna manufactures several K-type thermocouple probes for different applications.
See pages 14-17 for more details.
