HI 9040, HI 9041, HI 9050 and HI 9051 are microprocessor-based
thermometers which allow temperature measurement using a cali-
brated thermistor probe. The temperature probe is linearized by the
built-in microprocessor.
HI 9041 has been specifically designed by Hanna Instruments for use
in the food industry.
Standard features include:
• display and clearing of maximum/minimum temperature mea-
surements
• memory entry and hold
• low battery detection
Additional functions (HI 9050 and HI 9051) include:
• sound alarm with preset operating range
• display of constantly updated temperature differential between
stored and measured values.
These functions are easily accessible through the splash-proof mem-
brane keypad. Self-explanatory symbols are used to remind the user
of the operating mode or condition.
Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipment.
If noticeable damage is found, contact your Dealer immediately.
All models, except HI 9041, are supplied complete with an
HI 765BL temperature probe. A 9V battery is also included.
Note: Save all packing material until you are sure that the meter
functions correctly. Any damaged or defective item must be
returned in its original packing with the supplied accessories.
