All Hanna Instruments meters are warranted for two years against de-
fects in workmanship and materials when used for their intended purpose
and maintained according to instructions.
Sensors and probes are warranted for a period of six months.
This warranty is limited to repair or replacement free of charge. Damages
due to accidents, misuse, tampering or lack of prescribed maintenance are
not covered.
If service is required, contact the dealer from whom you purchased the instru-
ment. If under warranty, report the model number, date of purchase, serial
number and the nature of the failure.
First obtain a Returned Goods Authorization number from the Customer Ser-

4) Measurement mode
HI 8757
HI 8758
HI 8757 and HI 8758 are Hanna microprocessor-based, K-
type thermocouple thermometers specially dedicated to education.
These meters perform measurements either in °C (HI 8757) or
°F (HI 8758) in a wide range of temperature; readings are
linearized for increased accuracy, and resolution is automati-
cally switched from 0.1° to 1° for temperatures above 200°C
(400°F).
These thermometers are also provided with battery level
indication at start-up, and with the BEPS feature (Battery
Error Prevention System), which automatically switches the
instrument off when the battery is discharged to avoid
erroneous readings due to low battery level.
Each meter comes complete with a 9V battery and instruction
manual.
(*) Range may be limited by probe.
