The Hanna Instruments portable K-type thermocouple thermometers
with built-in printers are microprocessor-based and enable you to
accurately measure temperature and record data.
The instrument housing is made of rugged and lightweight material.
Equipped with a large, easy-to-read LCD, they feature an extended
battery life and a special design that enables results to be obtained
even in humid, wet or dusty conditions.
Measurements can be performed with lab-grade precision in the field
as well as in the laboratory without compromising accuracy. A 12VDC
car battery or a battery charger can also be used to power the unit
for extended use.
HI 92801 and HI 92804 have a memory capacity of 16,000
individual temperature readings with recording intervals selected by
the user.
Using the HI 9200 infrared transmitter, all the recorded data can be
transferred to a PC for easy reproduction, storage or elaboration
without the interference of cables and cords between the meter and
the receiver.
Other features include: on-board clock and date (HI 92801 and HI
92804 only), user-selectable printing/logging intervals, automatic
memorization of measured values (HI 92801 and HI 92804 only),
use of pre-calibrated completely interchangeable K-type thermocouple
probes, printing on plain paper, automatic shut-off capability, low
