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.

be returned in the original packaging together with

GENERAL DESCRIPTION

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.
